Fearsome Fanged Weevil - Cyrtepistomus castaneus

Fearsome Fanged Weevil - Cyrtepistomus castaneus
Alexandria, Fairfax County, Virginia, USA
October 19, 2011
Size: 5.5mm
The size is "nose" to "butt". I've never seen a weevil with fangs like this! It was a very tolerant subject when I brought it inside.

Near my door, presumably attracted to the patio lights.

many [most?] members of the subfamily have those fangs...
...during early hours of their life, then shed them off

Moved from Snout and Bark Beetles.

Dang
You are fast!! Thank you!

Sorry to see it's yet another Asian import - seems half the insects I find in my yard are. My patio is directly beneath a large oak, so I guess that's what it's after.

Fangs - I didn't know that! What's the purpose?

anytime.
function -- not sure at all; maybe helping to eclose?
btw, the presence of those deciduous mandibular processes is a major diagnostic feature of the subfamily
