This weevil emerged today 1-22-12 from this gall I brought into the house.

larval form?
perhaps this, found in white oak bullet gall in late February:

Moved from Myrmex.

Very cool
Nice find Tom.

 
I was surprised
to see a weevil instead of a wasp.

 
Myrmex laevicollis
Eyes very narrowly separated, small tooth on femurs, and relatively impunctate pronotum. Will keep weevil and gall as a photo-voucher, thanks Tom!

(The closely related wingless genus Oopterinus contains at least one species (O. perforatus) that are known from cynipid galls on oak roots.)

 
Second individual!!
There was a small round seed like object (a pupal cell) in the bag with the gall. I peeked inside and another Myrmex laevicollis was inside, though dead. This must be the round object in the interior of the gall seen in the third photo.

 
Two for the price of one:-)
Brad, thanks for the quick identification of the specimen! I had no idea that these weevils formed galls.
