2013 ESA World of Insects Calendar Selection

Today I received word from Richard Levine at the Entomological Society of America that one of my photos had been selected for the 2013 version of their famed World of Insects Calendar!

Excuse me for a moment please… (pumps fist, stirs the pot, does a very bad moon walk…)

Okay, I’m back. Honestly, this is an honor that I did not expect—at least not yet. Historically dominated by such giants in the world of insect macrophotography as Piotr Naskrecki,  Thomas Myers, and others, competition for ESA’s World of Insects Calendar is fierce. Last year more than 500 photographs were submitted for 13 slots (12 months and an introductory page) by 98 photographers from around the world. I was one of those photographers, though not selected (no surprise as I was a first-time submitter). However, I took great pleasure in seeing fellow bug blogger Adrian Thysse nab two of the 2012 slots, and I increased my resolve to try again for next year with a selection of eight mostly newer photographs.

At the suggestion of Dave Stone, I present each of those photos below along with a short description of why I submitted it. However, I’m not going to tell you which photo ultimately was selected—I thought it might be fun to see which photo you think was selected and why. As added incentive for guessing, I’m going to award 10 BitB Challenge points to each person who correctly picks the selected photograph. BitB Challenge Session #6 is coming down to the wire, so this could have a big impact on the overall standings.

The 2013 Calendar will become available for sale later this year (probably October) at the ESA website—last year’s version cost only $12 (discounted to $8 for ESA members, and free for those attending the annual meeting [which I will be attending this year]).

Megaphasma denticrus (Phasmida: Diapheromeridae) – giant walkingstick

From North America’s longest insect (21 Aug 2009).  This is one of my earlier super-closeup attempts. I liked the combination of blue and brown colors on the black background.

---

Buprestis rufipes (Coleoptera: Buprestidae) – redbellied Buprestis

From Special Delivery (13 July 2010).  The use of a white box shows off the brilliant (and difficult-to-photograph) metallic colors well, and I like the animated look of the slightly cocked head.

---

Edessa meditabunda (Hemiptera: Pentatomidae) – alquiche chico

From Stink Bugs on Soybean in Argentina (18 May 2011). I found these Edessa meditabunda stink bug eggs on the underside of a soybean leaf in Argentina almost ready to hatch. The developing eye spots in each egg gives the photo a “cute” factor rarely seen in such super close-ups.

---

Cicindela formosa generosa (Coleoptera: Carabidae: Cicindelinae) – eastern big sand tiger beetle

From Big, Bold, and Beautiful (10 May 2011). I like this slightly panned out view because of the sense of scale and landscape created by the inclusion of the plantlets and the view over the small rise.

---

Trimerotropis saxatilis (Orthoptera: Acrididae) – lichen grasshopper

From Oedipodine Rex (15 July 2011). Some of my favorite insect photos are not only those that show the bug in all its glory, but also tell a story about its natural history. This nymph is almost invisible when sitting on the lichens that cover the sandstone exposures in its preferred glade habitat. 

---

Tetracha floridana (Coleoptera: Carabidae: Cicindelinae) – Florida metallic tiger beetle

From Why I Roamed the Marsh at Night (23 August 2011). I used extension tubes to improve the quality of flash lighting (decreased lens to subject distance results in greater apparent light size), and I like the symmetry of the composition.

---

Spissistilus festinus (Hemiptera: Membracidae) – threecornered alfalfa hopper

From Crazy Eyes (17 September 2011). Even though both the insect and the background are green, there is sufficient value contrast to create a pleasing composition, punctuated by the bizarre zig-zag pattern of the eyes.

---

Crossidius coralinus fulgidus (Coleoptera: Cerambycidae) – a rabbitbrush longhorned beetle

From Crossidius coralinus fulgidus (4 October 2011). The blue sky background provides a pleasing contrast with the colors of this particular beetle and flowers.

BitB Best of 2009

In my first post of 2009, I looked back at the photographs I had posted during 2008 and picked some of my personal favorites. I hesitated then to call myself a photographer (and still do), but I at least now have suitable equipment to aid in my progress toward that eventual goal. I have learned much over the past six months in my first attempt at serious insect macrophotography (prioritizing in situ field photographs of unmanipulated subjects as a matter of personal choice).  Through this, I’ve come to realize the following skills to be the most important for success:  

1. Composition
2. Understanding lighting
3. Knowing how to use a flash
4. Knowledge of the subject

I’ll give myself a “A” in the last of these, but in the other areas I still have much to learn. With this caveat, and for the last post of 2009, I offer the following twelve photographs as my final choices for the 2nd Annual “Best of BitB”:  

Best beetle

Cylindera celeripes (swift tiger beetle), Woodward Co., Oklahoma

From Revisiting the Swift Tiger Beetle – Part 1 (June 30).  A decent enough photograph, especially considering that I’d had my camera for about a month when I took it.  However, the discovery of robust populations of this formerly rare and enigmatic species throughout northwestern Oklahoma (and later also in northwestern Missouri) was the most significant find of the 2009 field season, and this photograph is the best capture of that moment.

Best fly

Stylogaster neglecta, a species of thickheaded fly

From Overlooked, needle-bellied, thick-headed fly (Aug 14).  One of my first good “black background” shots.  The white tip of the abdomen compliments the white flower stamens against the background.

Best “true” bug

Beameria venosa, a prairie obligate cicada

From North America’s smallest cicada (Aug 4).  So many different shades of green with white frosting on the bug’s body.  I tried taking this shot in portrait and it just didn’t work—I liked this landscape shot much better.

Best predator

Promachus hinei (Hines giant robber fly) & Ceratina sp. (small carpenter bee) prey

From Prey bee mine (Sept 14).  Robber flies are immensely photogenic, especially those in the genus Promachus due to their prominent “beards.”

Best camoflauge

Dicerca obscura on bark of dead persimmon

From The “obscure” Dicerca (June 19).  Sparkling and gaudy as specimens in a cabinet, the coloration of many jewel beetles actually helps them blend almost perfectly with the bark of their preferred tree hosts.

Best immature insect

Tetracha floridana (Florida metallic tiger beetle) 3rd-instar larva

From Anatomy of a Tiger Beetle Larva (Oct 22).  “Otherwordly” is invariably the first word that comes to mind when someone sees a tiger beetle larva for the first time.  I was lucky enough to get this one in profile with a nice view of its abdominal hump and its curious hooks.

Best arachnid

Centruroides vittatus (striped bark scorpion)

From A face only a mother could love (Oct 6).  Despite some minor depth-of-field problems with this photograph, I’m fascinated by its “smile.”

Best reptile

Eastern collared lizard (Crotaphytus collaris collaris) adult male

From North America’s most beautiful lizard (July 10).  A simply spectacular lizard—all I had to do was frame it well and get the flash right.

Best wildflower

Spiranthes magnicamporum (Great Plains ladies

From Great Plains Ladies’-tresses (Dec 7).  Few flowers are as photogenic as orchids, even native terrestrials with minute flowers such as this one.  I like the frosty texture of the lip and the starkness of the white flower on the black background.

Best natural history moment

Thermoregulatory behavior by Ellipsoptera hirtilabris (moustached tiger beetle)

From Tiger Beetles Agree—It’s Hot in Florida! (Dec 18). I chose this photo for the classic “stilting” and “sun-facing” thermoregulatory behaviors exhibited by this tiger beetle on a blistering hot day in Florida.

Best closeup

Megaphasma denticrus (giant walkingstick)

From North America’s longest insect (Aug 21).  I haven’t tried a whole lot of super close-up photographs yet.  I liked the combination of blue and brown colors on the black background.

Best Landscape

Sand Harbor Overlook, Lake Tahoe, Nevada

From Sand Harbor Overlook, Nevada (March 23).   My choice for “best landscape” again comes from Lake Tahoe.  This is not a great photo technically—I was still using a point-and-shoot and had to deal with foreground sun.  However, none of the other photos I took during my March visit to the area captivate me like this one.  I like the mix of colors with the silhouetted appearance of the trees on the point.

North America’s longest insect

This past June might be the most successful month entomologically that I’ve ever had.  The excitement of discovering a robust population of Cylindera celeripes (swift tiger beetle) (previously considered one of North America’s rarest tiger beetles) in northwestern Oklahoma lasted only two weeks before being eclipsed by our long-awaited success at finding this same species also in Missouri.  Icing on the cake was provided by finding Ellipsoptera macra (sandy stream tiger beetle) – the last tiger beetle species we had yet to encounter in Missouri, and significant new records for the tiny prairie cicada, Beameria venosa, and the impressive robber fly, Ospriocerus abdominalis, in Missouri’s critically imperiled loess hilltop prairies.  With that rapid-succession-success, my thoughts immediately turned to another of Missouri’s unique natural communities – the dolomite glades of the White River Hills in the extreme southwestern part of the state.  In fact, I had already been yearning to return to the White River Hills, having last visited some years ago and recalling – from the perspective now as an insect photographer – the many photogenic insect species that I’ve encountered there.  Chief among them is Plinthocoelium suaveolens (bumelia borer), a spectacularly beautiful longhorned beetle of neotropical affinity that must be seen to be believed and which I had observed here several years ago in fair numbers as they perched on the lower trunks of their presumed larval host, Sideroxylon (= Bumelia) lanuginosa of the family Sapotaceae.  I had even mentioned to my colleague Chris Brown, as we began the first day of our planned multi-weekend search for C. celeripes and C. macra in northwestern Missouri, that my dream scenario was that we would find both celeripes and macra on that first weekend, negating the need for additional survey the following weekends, in which case we could shoot down to the White River Hills to look for Plinthocoelium.  Who knew how prescient that comment would be!

Megaphasma denticrus - giant walkingstick

I won’t keep you in suspense – I succeeded in finding and photographing Plinthocoelium, although (happily) there is more to the story than just that.  I’ll share that experience here soon, but first I want to discuss another insect I saw on the first of my two July visits to the White River Hills - Megaphasma denticrus¹ (giant walkingstick).  As implied by its common name, this walkingstick is enormous – females (typically larger than males) can reach lengths of 150+ mm (that’s 6 inches, folks!), making it officially the longest insect species in all of North America.  The female I feature here was solidly in that range, and with her front legs held outstretched in front of her (as pictured above), total length exceeded 8 inches.  Of course, this pales in comparison to a related species from Borneo, individuals of which have been documented measuring more than 18 inches in length!  The giant walkingstick is distributed primarily in the south-central U.S. – especially Texas, although records do exist from as far north and east as Iowa, Wisconsin, and Indiana (Arment 2005). I have encountered this species a few times before – always in the White River Hills, but Arment (2005) also records the species from several other counties in the Ozark Highlands across southern Missouri and Arkansas.  In addition to its great size, both sexes of this species can be distinguished from other walkingsticks by the rows of numerous teeth on the underside of the middle (meso-) femur (easily seen in the enlarged view of Photo 2 above) and by the very long antennae (longer than the front femur).  Color is variable – other individuals I have seen are tan with bright red dorsal stripes on the thoracic segments.

¹ Formerly classified with grasshoppers and their kin in the order Orthoptera, walkingsticks are now placed their own order, Phasmatodea, the name being derived from the Greek phasma (apparition, ghost) in reference to their cryptic appearance and behavior (the alternative spellings Phasmodea and Phasmida are improper formations from the Greek root – see Grimaldi and Engel 2005).  The genus name, Megaphasma, thus means “giant walkingstick.”  The specific epithet, denticrus, is derived from the Latin den (tooth) and crus (leg), presumably a reference to the toothed underside of the mesofemur. Many authors, including even some taxonomists (e.g., Beamer 1932), have mispelled the name as ”dentricus” – nonsensical in Latin – with some even using both spellings in the same paper (e.g., Maginnis et al. 2008)!

Of course, an outstanding feature of this species, and all walkingsticks in general, is its uncanny resemblance to sticks and twigs.  This cryptic appearance is further augmented behaviorally by the habit of “swaying” back and forth to simulate movement in a gentle breeze.  I must confess that I did not even notice this large female individual – less than two feet away on a low branch – until she started moving about.  Once spotted, a walkingstick of this size would seem to be a tasty – and defenseless – morsel for some avian predator; however, they have another defensive tactic up their sleeve – autotomy (i.e., the ability to shed appendages in response to predatory attack). While it may seem that their long, delicate-looking legs are simply “pulled off” by the predator, fortuitously allowing the walkingstick to clamber to safety, leg shed is actually controlled by the central nervous system in response to external stimuli (e.g., grabbing of the leg).  Breakage occurs at predetermined abcission points, which are rapidly sealed after shedding to prevent excessive loss of body fluids.  I experienced this first hand – lacking any container large enough to hold the enormous female, I gently placed her into my net and gingerly carried her back to the truck, only to find a hind leg already shed by the time I got back.  I decided the effort to glue one (or more) legs in place to acheive a well-curated specimen exceeded my interest in starting a collection of this particular group of insects, so I let her go.  Presumably she crawled away to safety, though sadly no longer the ‘perfect’ specimen that I first encountered.
