Aphodius rusicola

Aphodius rusicola
Tippecanoe County, Indiana, USA
July 9, 2007
Size: ~ 4 mm
An Aphodius sp. I've been thinking A. granarius but I'm not sure. A series of 4 specimens ranges from 4 to 5 mm. Found at UV light.

Some characters: elytra not pubescent dorsally or apically; front tibiae not punctate on outer surface; clypeus not toothed; front tibial spur normal, not modified; head weakly trituberculate; pronotum with basal marginal line; clypeus and head to some degree dull, less shiny than rest of dorsum.

Moved from Aphodius.

rusicola seems more likely
very common sp.

Thanks. I now see how this keys out. Gordon (1983) spells this as "ruricola", which I assume is a misspelling. I don't know which subgenus this should be in so I'll let you move to a guide page.

I'll check and move
other mispellings from Gordon include A. badiceps Fall -> should be A. badipes Melsh. (=oblongus auct.) and A. phaleroides -> phalerioides

colour . . .
atypical for granarius (at least judged from Europe, ours are all black, if mature). May fit otherwise, but Aphodius ID by photo is really problematic.

It was hard to get good images of this one, so I had to increase the lighting. It is black under normal lighting, but under a scope you see that it has a dark reddish color.

I'll add some characters above.
