Root Weevil - Otiorhynchus sulcatus

Root Weevil - Otiorhynchus sulcatus
Salt Lake City, (40°46.727'W111°52.629'ele4609'), Salt Lake County, Utah, USA
July 18, 2005
Size: 9mm
Close-up of cf. Otiorhynchus. I've heard that these are parthenogenic (no males), any confirmation?

Moved from Broad-nosed Weevils.
ID is safe.

Curculionidae: Otiorhynchus sulcatus
While it is possible there is an O. sulcatus look-alike out west, this would be a typical O. sulcatus in New England.

This is most likely
sulcatus. The three introduced species (sulcatus, rugosostriatus, and ovatus) seem to occur where plants are cultivated commercially. Other than large with a patchy pattern, medium with a sorta uniform pattern, and small and shinier, I have yet to find characteristics that are more exact. Should explore the literature a bit more.

Otiorhynchus sulcatus?
This looks like my broad-nosed weevil that Eric Eaton identified as O. sulcatus.
