Beetles (Coleoptera) of Brush Mountain

six-spotted tiger beetle

Compilation date: Begun January 1994 (ongoing)
Number of species: 211
Main contributor: Steve Bonta
Main source: Bonta-Wells Field Collection; field observation by S. Bonta.

The Coleoptera of Brush Mountain probably represent the single largest class of living thing on the property, as they do worldwide. Steve estimates that with copious collecting, during the course of a year, between three and four times the number of species listed could be found.

The list is arranged alphabetically by order, not phylogenetically, then alphabetically by genus and species. Due to the difficulty in separating many species of beetles and the paucity of comprehensive field guides, many of the insects have not been identified to species. In particular, some species of staphylinids, curculionids, and even elaterids are still not identifiable, since certain very large genera containing many small beetles with very similar characteristics have not been comprehensively worked by taxonomists. the staphylinidae in particular, at once the world’s largest family of beetles (and hence of all living things) as well as one regarded as among the least charismatic by entomologists, has never gotten sufficient scientific attention; it is estimated that up to half of all tropical staphylinids remain unnamed, and certainly dozens of North American species, surprisingly, are still unclassified, including in all likelihood some found on the property. This is also the case for a couple of the elaterids given to genus. For hard-to-indentify taxa in particular (such as the many Mordellistena spp.), I have included a few “naked-eye” fieldmarks, to aid in identification and observation of living individuals with nothing more than a hand lens.

As of this writing (May 2007), this is very much a work in progress, with many minor families (such as the Ptiliidae and Colydiidae) that doubtless occur on the mountain uncollected, and many major families (such as the aforementioned Staphylinidae, the Carabidae, the Curculionidae, the Chrysomelidae, and the Scarbaeidae) insufficiently worked. In view of this, I anticipate a more comprehensive list will eventually contain hundreds of species, and at least a dozen families, that the current list does not account for.
