We’ve recently updated the BFS invertebrate list, and I’m afraid that our blog posts have not kept pace with our new invert finds. Altogether since our last invert blog update, we’ve added an additional 57 taxa, including 3 spiders, 1 silverfish, 1 dragonfly, 2 grasshoppers, 6 bugs, 10 beetles, 10 flies, 5 moths, 3 butterflies, 5 bees, and 11 wasps.

Many thanks to everyone who’s helped observe, photograph, collect, and identify these inverts, including Hartmut Wisch; Doug Yanega, UC Riverside Entomology Museum; Jim Hogue, Cal State Northridge Biology Department; Molly Rightmyer Gee, San Diego Natural History Museum; Andy Hamilton, Canadian National Collection of Insects, Arachnids and Nematodes; John Ascher, American Museum of Natural History; Andy Calderwood, Ventura County Agricultural Commissioner’s Office; David Furguson, Rio Grande Botanic Garden; Adriean Mayor, Great Smoky Mountains National Park; David Smith, Smithsonian Institution; and the many folks at BugGuide.

Here’s the complete list of new taxa with a sampling photos. Photos of most of the taxa are linked to the list.
