Margined Leatherwing

Chauliognathus marginatus

Description:

Very similar to C. pennsylvanicus, but pronotum has wide dark band, instead of an irregular dark spot. Elytra of C. marginatus often more extensively dark than pennsylvanicus. C. marginatus is also somewhat smaller and is active earlier in summer than C. pennsylvanicus.

Habitat:

Old field habitats with flowers.

Notes:

Not the best shot since it's just of the back but does anyone know what kind of bug this is? It's it a firefly? - UPDATE I found more pics of it, these were taken in a different location at a different time but I think it's the same beetle.

This is the only member of the genus that is active in Oklahoma in May - other species appear later in the summer or into the fall. The smallish spots and what is visible of the pronotum (the area between the wings and the head) also match the Margined Leatherwing.
