Moved from Bledius. ID'd from specimen, now a photo-voucher. Thanks Lisa.

These are tough, but I've convinced myself this belongs in the semiferrugineus group after digesting Herman's keys. The species seems to be B. philadelphicus or at least near that, but I'm not certain enough to assign to species and the closest that species has been recorded to you is Maryland. The specimen is intriguing to me because after checking the several dozen Bledius in my collection, none have the distinct microsculpture on the pronotum like this one.

Try to find more of these if you can. Bledius are fairly diverse and you can probably find several species in the same area. They are typically found along the margins of water in burrows in mud, sand or gravel bars. They also can be quite common at lights.

Moved from Rove Beetles.
