Water Scavenger Beetle - Hydrochara soror
Copyright © 2005 Cotinis

Water Scavenger Beetle - Hydrochara soror
Hwy 55 and Sedwick, Durham County, North Carolina, USA
June 30, 2005
Size: 16 mm
Underside, showing the spine that does not extend past metasternal coxae. This differentiates, I think, from the similar genus Hydrobiomorpha.

looks to be H. sorror
from Downie and Arnett, this one looks to be H. sorror Smetana. From the key, the metasternal part of the keel appears no more than slightly dilated, and the apex of the maxillary palpomere appears darkened. The description states H. sorror is reddish to pale reddish brown on legs and venter. 14-19mm. Distro includes NC. Your other Hydrochara post appears to be the same.

Thanks again, another
I just posted another one--looks somewhat different:

The keel and palpi look correct for Hydrochara soror, but the coloration is much less rusty underneath on this one.

Comments?
