Lixus weevil

Lixus sp.

Description:

A weevil with mottled brown coloration, about 1 cm in length.

Habitat:

Found on my car, parked near a fragment of oak-hickory forest.

Notes:

According to Bugguide.net, there are two ways to distinguish L. concavus from L. mucidus. 1. L. concavus has a conspicuously large indentation (hence concavus) at the back of the pronotum/front of the elytra, while L. mucidus has a much less pronounced concavity; 2. L. concavus has a yellowish "bloom" that rubs off when handling the weevil, while L. mucidus has a whitish bloom. I didn't handle this guy and don't know about the bloom (online images of the color of the weevils with bloom look much the same to me in that aspect). I can't see any conspicuous indentation in my spotting, so I'm leaning toward L. mucidus. As always, any help in identifying the species is greatly appreciated.

ID update: I posted pics to BugGuide.net. So far, Lixus is confirmed, and concavus has been excluded as the species. A more specific ID may come later. http://bugguide.net/node/view/778786

Keith, Thanks for the support of Lixus. I had tried to figure out how to distinguish L. concavus vs. L. mucidus, and the apparent lack of a deep impression in the pronotum-elytra junction is what made me think it's more likely L. mucidus. I'll keep at it!

It certainly looks like Lixus. I'd vote for L. concavus, but I'm no expert.
