Friend and colleague Mathew Brust takes credit for two of the three tiger beetle papers. In the first (Brust et al. 2010), he compares the efficiency of the three main methods for collecting tiger beetle larvae: fishing, stab-and-grab, and excavation. They found fishing to be the most efficient and least damaging of the three methods, an important finding for tiger beetle conservation where the availability of efficient, non-lethal survey methods is critical. (What are “fishing” and “stab-and-grab” you ask? Read the paper.) In the second paper (Brust and Hoback 2010), Matt teams up with University of Nebraska entomologist Wyatt Hoback to provide new distributional records and larval descriptions of Nebraska’s tiger beetle, Cicindela nebraskana. Ironically, this species is quite rare in it’s namesake state, and their findings give clues about the habitats in which it is most likely to occur (I had the good fortune to contribute a small amount of data). In the third tiger beetle paper, Robert Richardson (2010) notes an overwhelming preponderance of left-superior mandibles in two species of Omus and speculates on the selective pressures that might operate on different tiger beetle clades to produce such a finding – a truly interesting read.
As for longhorned beetles, Sánchez-Martínez et al. (2010) report the utilization of living oaks by an apparently disjunct population of the marvelously beautiful Crioprosopus magnificus in central Mexico, complete with photographs of the larval workings and detailed emergence data. (I am also reminded that I have a post on this very species that I need to put up). Closer to home, Terence Schiefer and Patricia Newell (2010) independently recognized the existence of an undescribed subspecies of the red-edged saperda, Saperda lateralis, in the lower Mississippi Delta Region of the southeastern U.S., which together they describe as S. lateralis rileyi (named for Edward Riley, indefatigable collector of beetles, and collector of much of the type material). Okay, I know what you’re thinking – “A new subspecies of S. lateralis? No way!” Well, I was skeptical also when I first saw the title – several untenable and no longer recognized subspecies have already been described for this broadly distributed and variable species. However, after noting the nature of the diagnostic characters, seeing the photographs, and studying their partially allopatric distributions, I was convinced.
In addition to the above papers, there were also a number of interesting book reviews in the issue, including The Chiasognathinae of the Andes, reviewed by M. J. Paulsen, A Field Guide of the Dynastidae Family of the South of South America, reviewed by Ronald M. Young, and three book reviews by our beloved Art Evans: Illustrated Identification Guide to Adults and Larvae of Northeastern North American Ground Beetles (Coleoptera: Carabidae) [including tiger beetles]; The African Dung Beetle Genera; and Weevils of South Carolina (Coleoptera: Nemonychidae, Attelabidae, Brentidae, Ithyceridae, Curculionidae).
