I recently conducted a complete reorganization of the jewel beetles (superfamily Buprestoidea) in my collection (TCMC). The primary purpose of this was to bring the nomenclature and arrangement of the collection into agreement with the recently published World Catalogue of Buprestoidea (Bellamy 2008) and accurately document the taxa represented in the collection and their numbers. In the short term this will be helpful not only in visualizing what is represented but also what is missing (particularly in North America), while longer term it lays the groundwork for the eventual donation of my collection to a public institution.

In an active, working collection, no inventory is ever fully up-to-date. In my case, the inventory includes only completely curated material that has been incorporated into the main cabinets. I still have several years worth of material in various states of curation—i.e., unmounted, mounted but unlabeled, or labeled but unidentified. That said, the main collection now contains more than 23,000 specimens of Buprestoidea representing 1,500+ species worldwide. Of the species represented, 37% are Nearctic (U.S./Canada), 22% Palearctic (Europe, North Africa, temperate Asia), 19% Neotropical (Latin America), 10% Afrotropical (Subsaharan Africa), 7% Indomalayan (tropical Asia) and 6% Australian (Australia/New Zealand). The collection also contains 492 paratype specimens representing 77 species. The inventory has been converted to  PDF and uploaded for access by the link below. It lists all of the species represented, with nomenclature updated and taxa arranged according to Bellamy (2008) and number of specimens  indicated for each. Also indicated are higher taxa not yet represented in the collection (shown in gray rather than black text) so that the collection holdings can be placed in context of a complete higher classification for the superfamily.

Of course, as a North American, the Nearctic fauna is the primary focus of my taxonomic and biological studies. As a result, I am keen to have the Nearctic fauna represented as completely as possible in my collection. Currently I have 75% (595) of the 790 species and non-nominate subspecies currently recognized in North America. Obviously, by now I’ve picked most of the low-hanging fruit, and the last 25% will be much more difficult to get. Many of these are truly rare species that I may never find (some are known only by the holotype), while others are more common but occur in areas that I have limited opportunity to visit. These species are also indicated in the above inventory (again, in gray text) but are also listed below for easy reference. If you have any of the species on this list, please let me know and also what you might like to receive in exchange for them. I have not only many species of Buprestidae from around the world to offer, but also beetles in other families such as longhorned beetles (Cerambycidae), tiger beetles (Cicindelinae), scarabs (Scarabaeoidea), and even non-beetles such as treehoppers (Membracidae) and cicadas (Cicadoidea). Let’s make a deal!

Beautiful box of Buprestidae

I’ve been working on identifying Buprestidae accumulated from a variety of sources over the past year—mostly exchanges and gifts, before beginning the processing specimens collected during this past season. Once identified, and combined with specimens gleaned from material submitted by other collectors for identification (I generally only retain examples of species that are poorly represented in my collection or specimens that represent and will serve as vouchers for significant new distributional records), they make for a very pretty box of Buprestidae! It’s kind of nice to keep them collected together like this for a little while, but I’ll soon incorporate them into the main collection where they will more securely protected and to free up the temporary box now containing them for new material as it moves through the process of labeling and identification. (Incidentally, I think I might like to do a series a posts over this winter covering my version of the specimen curation process).

There are some very cool Buprestidae in this box—88 species in all, that originated from a remarkable variety of locations across the U.S., Mexico/Central America, and South America. Do you see any species of particular interest?

The Ups and Downs of Bug Collecting

Recently The Geek In Question  posted an awesome graph to help visualize the stages of euphoria and despair she experiences while going through the manuscript process. Fellow grad students David Winter (The Atavism) and Morgan Jackson (Biodiversity in Focus) each took the bait and ran with their own version of the process. It has been far too many years since I was a grad student (moment of whimsy overtakes me), and I’ve gone through the manuscript process so many times now that I actually find the whole thing rather enjoyable. Presumably this results from my love of writing, combined with the sageness of having experienced most of the potential pitfalls and feeling confident in how to prevent or deal with them.

For my version of the Geek-Graph™, I thought I would take a broader look at the whole process of what it is to be a publishing Bug Collector. Here is my version:

I’ve been at this long enough to know what I like and what I don’t like, and it strikes me that I love the up front and the final product, but there are elements in between that I simply detest. I love time in the field—a bad day in the field is better than a good day of just about anything else. Some of my best field memories involved getting skunked on the collecting, just because the field experience itself was so weird, new, eventful, etc. I’ve spent days in the desert, it’s dry environs parched by drought, with nary a beetle to be had despite beating hundreds of tree branches. I hated it at the time, but I get euphoric recall of those days when I see something that reminds me of those trips. Even driving between localities, while not time “in the field,” is enjoyable for me as it’s a chance to see the landscapes. It’s only when I have to take time out to buy supplies mid-trip and, especially, hunt for hotels late in the day, that I stop enjoying my time completely.

After I’ve collected the specimens is where I hit the snag—pinning and labeling, ugh!!! It wasn’t always that way; in my younger days I rather enjoyed it. But in those days I was practicing my art and gaining skills. Now I’m as good at pinning/labeling as it gets, and my perfectionist tendencies don’t allow me to do anything less than perfect when I do do it. But it takes time—lots of time to do it perfectly, and especially when you collect the large numbers of specimens that I do. This is the point where I consistently question my decision not to pursue taxonomy as a career. I could have been enjoying the assistance of professional specimen preparators to take care of this for me, but nooo… I had to do it avocationally so I could “do my own thing”! Okay, a quick slap to the face and I’m back.

Once those specimens are pinned and labeled, it’s all fun from here on out.¹ Identifying specimens and adding my “Det. label” is enormously satisfying, even for routine, common species. Excitement mounts if the specimen turns out to be something rare, more so if it represents something I’ve not collected before. This is normal for all collectors, but for me there are additional chances for excitement if the specimens represent new information—e.g., a new state or host plant record, or (gulp!) a new species! Identified specimens also form the basis for manuscripts, and once I’m at that stage it’s pure happiness. I love writing the manuscripts. I even love revising them based on reviewers feedback (even when not very positive—hey, it makes for an improved paper). About the only negative is a little bit of post-publication depression when you realize that your paper is actually read by only a small number of specialists, and you haven’t really offered anything ground-breaking, but rather just an incremental increase in the vast, collective knowledge. But I usually don’t have time to let that get me down—by then I’m already out in the field collecting more bugs!

¹ I probably should make a confession here—sometimes I go ahead and include data in manuscripts from specimens that I haven’t even pinned and labeled yet. The siren call of the unwritten manuscript is far more irresistible than the grating nagging of the unprepared specimen!

MacRae Entomology Museum Expansion

Badly needed drawer space is provided by these gorgeous, antique, hand-made, wooden insect cabinets.

Every five years or so I find myself facing the same dilemma—too many bugs and not enough space to keep them. Each time this occurs, I go through the same thought process trying to decide the best way to solve the problem. Do I create new space by buying new cabinets, or clear existing space by donating “excess” material? If money was no object it would be the former. However, money is an object—a new, premium 25-drawer cabinet costs more than $1,000, not to mention another $400 for the drawers to fill it (if I build them myself—3 times that amount if I buy them already made). In my younger, more care-free days I got away with plunking down this kind of money several times, eventually assembling my current battery of three half-size and three full-size cabinets holding a total of 111 Cornell drawers fully stocked with unit trays. These days, however, there are kids to feed and college costs looming on the horizon. I just can’t swing that kind of dough.

Each cabinet came complete with 10 hand-made, wooden, glass-topped drawers.

The alternative, however—donating away part of my collection, is equally unattractive. I’ve been collecting insects for most of my life, so it’s more than just a hobby—it’s a part of me. Nevertheless, I am able to draw a distinction between a working collection and a hobby collection, and for the most part mine is the former. I have a few “hobby” taxa like treehoppers and leaf beetles and such, and I’ve already made a number of donations from these groups over the years. However, the bulk of my collection—and hence drawer space—is taken up by just three taxa; jewel beetles, longhorned beetles, and tiger beetles. Not only are my research activities in these three groups ongoing, but a considerable amount of the material in these groups consists of voucher specimens for my publications. I just can’t think about divesting myself of material in these groups, at least not at this point in my life. Besides, pulling material for donation is, in itself, a long and very time-consuming process that I would not look forward to.

I’ve actually been debating my options for the past couple of years now, watching nervously as my inventory of specimens housed in temporary cardboard boxes started to balloon from the successes of the past several years of collecting. Temporary boxes are bad—not only is it impossible to integrate the specimens into the organization of the main collection, but they remain vulnerable to that dreaded pest of insect collectors around the world; DERMESTID BEETLES! (The one beetle I don’t like!) The likelihood of having specimens damaged by dermestids is directly proportional to the number of temporary boxes that must be checked periodically looking for any evidence of their presence. I’ve been hit by dermestids more than once, and with the number of temporary boxes that I currently have (more than 50) it has become almost impossible to monitor them frequently enough.

Unit trays designed for Cornell drawers fortuitously fit nicely inside the custom-sized drawers.

Of course, patience is a virtue, and my reward this time for not acting too rashly came in the form of an email sent to the members of our local entomology group by Mark Deering, Director of the Sophia M. Sachs Butterfly House just a few blocks from my office. Mark was an avid butterfly collector in the past but has divested much of his collection in recent years and, as a result, no longer needed the cabinets and drawers he was using to store his collection. The list of items he had for sale included a few Cornell cabinets with drawers, ostensibly perfect for my needs, but it was the last item in the list that caught my eye—several antique, hand-made, wooden, 10-drawer cabinets with drawers. Now, I love my Cornell cabinets—they provide state-of-the-art (albeit industrial-looking) protection for my collection. However, there is something appealing about hand-made, wooden insect cabinets. I can almost see John L. LeConte and George W. Horn themselves standing next to one and pulling a drawer to have a look at its contents. I quickly contacted Mark and made arrangements to look at the cabinets. Mark explained that they were part of a 40-cabinet set housing a collection of pierid butterflies that eventually found its way to the Smithsonian Institution… yes, the Smithsonian (such history!). He had gotten ahold of seven cabinets and was now selling them for a very reasonable price. The cabinets were gorgeous, and it didn’t take long for me to do the math; I could afford to buy three cabinets with drawers for a fraction of what a 25-drawer Cornell cabinet with drawers would cost. That’s 30 drawers total, each with almost as much space as a Cornell drawer.

Drawer 1 of my tiger beetle collection.

I picked up the cabinets a few days later and spent the next two days rearranging furniture in my ‘museum’ to create the perfect showcase spot, cleaning the glass on each drawer (both sides), and transferring my tiger beetle collection into the first cabinet (drawer 1 of which is shown at right). Despite their age several transfers of ownership, the finish is still in very good shape with only minor nicks and scratches that add a sense of history yet don’t detract from their attractiveness. Especially pleasing was the discovery that the Cornell unit trays I use for my collection fit almost perfectly in the drawers (just an annoying empty spot in the upper right corner—this can probably be fitted with a California Academy-sized unit tray, perhaps for holding insect repellent blocks since the drawers and cabinets are not as air-tight as my modern Cornell cabinets). I’ll probably move the rest of my “hobby” taxa into the remaining drawers to free up the Cornell cabinets completely for exclusive use in housing my Buprestidae and Cerambycidae. That will take some time, but it’s a good problem to have. My only fear is that after I move things around and incorporate all of my backlogged material, I will have once again used up all of the newly available drawer space and find myself facing that same dilemma that I face every five years or so!

Perhaps a little teaser is in order—one of the species in the drawer shown at right will be the subject of an upcoming post—can you guess which one? Also, 2 BitB Challenge points to anyone who can correctly identify the country shown in the map behind the drawer.

Something for Adrian

Miscellaneous North American Cerambycidae - click for larger version (1680 x 1120).

In a comment on my Buprestidae exchange post, Adrian Thysse asked to see hi-res images of specimen drawers from my own collection. Like any good North American entomologist, Adrian was a little bothered by the card-mounting technique used by the sender of the specimen box featured in that post and wanted to see what a nice collection of properly pinned specimens might look like. It’s actually not the first time he’s made this request—back when I first moved this blog to WordPress (more than three years ago) he did so when I put up my Collection page featuring a photo of my “Oh wow!” insect drawer. I’ve thought about doing this ever since he first made this request, but the problem, or at least my problem, with photographing specimen drawers from my main collection is a combination of large drawer size (reducing the size of the specimens in an image of the drawer) and long series of a relatively small number of species in the same genus or closely related genera (making the drawer contents look rather uniform in appearance). I suppose some might still be interested in seeing drawers from a “working collection” such as mine, but I just never had enough motivation to start pulling out drawers and taking photos.

Adrian is in luck, however, as I just happened to be putting together a shipment of miscellaneous North American Cerambycidae for a collector in Europe (to whom I’ve owed insects for longer than I like to admit). The box I’m using for the shipment is smaller than a normal collection drawer and is packed with close to 100 species of this diverse beetle family. There might be a specimen here and there that was collected by someone else, but the vast majority were collected, mounted, labeled, and identified by me. I show this as an example of my curatorial technique, and as a bonus the above image is linked to a fairly large version (1680 x 1120) for those who might be interested in getting a really close look at the specimens and their labels. Here also are closer looks at the specimens in the bottom left and bottom right corners, respectively:

Hmm, is that a wasp at the bottom?

What species is that without the ''normal'' ID label?

Buprestidae exchange

With my queue of specimen identifications now clear, I can turn my attention to another major backlog that I haven’t been able to give proper attention recently—exchanges. For those of you not into insect collecting, exchanging is something that most collectors eventually end up doing, especially if the goal is to build a taxonomic reference collection within one’s chosen group that has broad representation of species and higher taxa from multiple geographical regions. Truthfully, I don’t do nearly as much exchanging as some collectors I know. It’s not that I don’t want to, but simply a matter of time—receiving and incorporating shipments while preparing and sending out returns is not as quick and easy as it might seem, not to mention the time involved in mining and corresponding with prospective exchange partners. I wish I could do more, but since I can’t I deal with it by limiting myself almost exclusively to exchanging Buprestidae (although I’ve been known to do a tiger beetle exchange or two). I focus on Buprestidae because that is my primary group of taxonomic interest.

Buprestidae received in exchange from Stanislav Prepsl, Czech Republic

These photos show some of the Buprestidae I received this past year, this particular box coming from Stanislav Prepsl in the Czech Republic. This is the first time that I’ve exchanged with Stan, and I must say I am impressed with the quality and taxonomic diversity of his buprestid holdings. In this exchange, I received 73 species, most of which are represented by a male/female pair and four represented by paratype specimens. These are all Old World species, and while a few are from the well-known fauna of Europe most were collected in countries seldom visited by (or even off limits to) American collectors such as the former USSR, Iran, Pakistan, Kurdistan, Turkey, etc. There are a nice few species also from Namibia, Kenya and Ethiopia. In return, I sent to Stan more than 100 species of Buprestidae from mostly the southwestern U.S. and Mexico where I have done a large part of my collecting. Stan was less demanding about receiving both one male and one female for each species, thus the larger number of species I was able to send him for approximately equal numbers of specimens.

Some collectors avoid Buprestidae because of their taxonomic difficulty and the overwhelming numbers of small, difficult-to-identify species. I think this is exactly why I like the group, and though many of the species are small they are certainly no less beautiful than their larger, flashier, more ostentatious brethren. I include this close-up view (you might recognize the specimen in the lower right corner as the previously featured Agelia lordi) to show the meticulous preparation of the specimens included in the shipment—an example of a well-curated collection by someone who knows what they are doing. Incidentally, the cards on which the specimens are mounted are standard fare among European collectors, and although as an American I prefer direct pinning of larger specimens and mounting smaller specimens on points versus cards, I’ve come to appreciate the exacting care with which some Europeans practice this card-mounting technique.

It’ll take me a few hours of dedicated attention to move all of these specimens into the main collection—not only must their proper placement be determined, but there is usually a lot of reshuffling of specimens within and amongst unit trays whenever such a large number of specimens is incorporated into it. With 15,000 described species and counting, this sending of Buprestidae represents only a modest increase (0.5%) in my representation of species; however, it adds representation from geographical areas that previously had virtually no representation in my collection at all. I hope Stan is as pleased with the material that I sent to him as I am with this material, and I look forward to the opportunity to exchange again with him in the near future.

A First Class Box of Beetles

Warning: post contains lots of hardcore, beetle-collector geekery!

A nice selection of tiger beetles and buprestid beetles.

A few weeks ago I got an email from fellow buprestophile Henry Hespenheide (Professor Emeritus, UCLA) asking if I needed any specimens of Agrilus coxalis auroguttatus - recently dubbed the “goldspotted oak borer” after it was discovered damaging oaks in southern California (Coleman & Seybold 2008).  I replied that I did not have this species in my collection and that I would be grateful for any examples he could provide.  Shortly afterwards, I received another message from him saying that he had just placed in the mail a small box with a male/female pair of that species – along with about two dozen tiger beetles for my enjoyment!  Later that week I received the shipment at my office – I couldn’t wait to open it up and see what goodies were inside!

Ctenostoma maculicorne (Chevrolat, 1856)

Opening a box of just received specimens is a little like opening presents on Christmas – you don’t know for sure what’s inside, but you know you’re gonna like it!  This time was no exception, and I delighted as I realized the sending contained a dozen or so tiger beetles from Costa Rica and Nicaragua (a region in which Henry has spent many of his years studying the leaf-mining and twig boring buprestid beetles).  My eyes were immediately drawn to two tiger beetles in particular – specimen #1 in the first row, and specimen #4 in the second row.  Why these particular tiger beetles?  Obviously they are among the more showy specimens in the sending, but more significantly both of them belong to genera not represented in my collection.  The first of these is Ctenostoma maculicorne, representing also a new tribe for my collection (Collyridini, subtribe Ctenostomina).  I’m glad Ron Huber had already identified this specimen, as I probably would’ve only been able to determine the genus.  Beetles in this group are ant mimics, but in a much different manner than our U.S. ant-mimics (Cylindera cursitans and Cylindera celeripes).  Those latter species are found strictly on the ground (as are all U.S. tiger beetle species), while species of Ctenostoma are largely arboreal.  Troy Bartlett at Nature Closeups has some great photographs of another species in this genus seen last January in Brazil (Caraça Natural Park, Minas Gerais) that show just how ant-like these beetles can appear as they crawl about on twigs and branches.

Pseudoxycheila tarsalis Bates, 1869

Despite lacking an identification label, I recognized the second specimen instantly as Pseudoxycheila tarsalis, dubbed by Erwin & Pearson (2008) as the “Central American montane tiger beetle.”  Pseudoxycheila is a rather large Neotropical genus (21 known species), but only P. tarsalis occurs north of South America.  Morgan Jackson at Biodiversity in Focus photographed an individual of this species during his visit to Costa Rica this past summer.  Its brilliant coloration is not only delightful to look at but also apparently aposematic in nature – Schultz and Puchalski (2001) found that benzene-like compounds isolated from the beetle’s pygidial glands are distasteful to humans, adding support to the potential of a Müllerian mimicry association with stinging mutillid wasps in the genus Hoplomutilla, which they resemble.  Note also the curious spine on the frons extending out over the mandibles – maybe it not only grabs its prey with its toothy jaws but also “stabs” it for extra measure (just kidding – though I do wonder about the function of that spine.  I’m not aware of its presence in any other genus of tiger beetles).

I also noted an interesting pair of tiger beetles that looked very different from each other, yet were both identified by Ron Huber as Tetracha ignea.  This species was recently synonymized under the nominotypical form of T. sobrina (Naviaux 2007) – the “ascendent metallic tiger beetle” (Erwin & Pearson 2008), a highly variable species with numerous described subspecies occurring in southern Mexico, Central America, northern South America, and the West Indies.  The specimen on the left has the normal appearance of T. sobrina sobrina, but the specimen on the right looks like it might have suffered some chemical discoloration (a common occurrence among collected tiger beetle specimens).

Update 16 Dec 2010, 12:00pm – I just learned from Henry that the Tetracha specimen on the right (from Nicaragua) was not seen by Ron Huber and, thus, is likely not conspecific with the specimen on the left (T. sobrina from Costa Rica).  That’ll teach me to blindly accept what I see but does not seem right.  Now, time to pull out my copy of Naviaux (2007) and test my abilities to work through a key written in French!

Tetracha sobrina sobrina Dejean, 1831 (L); Tetrach sp. undet. from Guatemala (R).

There are several other interesting species in the sending – some determined (two species each of Oxycheila and Brasiella) and others that I need to look at more closely.  You may note on the bottom row a few specimens of a species of Elaphrus - a genus of true ground beetles that often fool collectors by their strong resemblance to tiger beetles (looks like they fooled Henry, too).  As for the beetles that were the reason for this shipment in the first place, these are shown in the image below.  Agrilus coxalis auroguttatus was recently discovered as the cause of significant mortality in several species of oak trees in San Diego County (Coleman & Seybold 2008), thus joining the introduced Agrilus planipennis (emerald ash borer) and several native Agrilus spp. on the ever-growing list of buprestid beetles achieving economic pest status in North America.  This subspecies, known for many years from southern Arizona (where it is not a pest), is curiously widely disjunct from nominotypical populations in southern Mexico.  Its sudden appearance in southern California has all the hallmarks of being a human-aided introduction, although natural range expansion remains a possibility.

Agrilus coxalis auroguttatus Schaeffer, 1905

My deep appreciation to Henry Hespenheide for gifting me these specimens and for his always enlightening and often entertaining correspondence over the years.
