Curculionidae, dorsal - Bagous americanus

Curculionidae, dorsal - Bagous americanus
Anderson Lake, Hamilton County, Iowa, USA
May 28, 2008
Size: 4+ mm
Found on a water lily. It had lots of debris on it. Tried to clean off the dorsal side.
If I had to guess, I think it looks like something in Bagoinae.

Moved from Bagoinae.

Bagous americanus LeConte A widespread US and Canadian species that mines the leaves of water lilies and pupates in the crown of the petiole. Often adults sit on the underwater edge of the leaves in the daytime. They can be collected by finding mined leaves and turnimg then gently to see the weevils. At night the adults come onto the top of the leaves to find mates and to replenish their air supply.
Good job cleaning the specimen without removing the scales too. If not cleaned these are almost impossible to ID.

Thank you.
As much as I appreciate knowing the name of an insect, I am most interested (and delighted) in learning some of the the ecological information that is known about it. Very good indeed. Thanks again.

I probably shouldn't say what I cleaned it with; a fine brush and (spit).

thank you both so much for the addition
as a side note, spit has any number of uses in bug-handling business

Actually v
I've been going to ask you about that. How sanitary should one be? These insects have been frozen or dead for a long time.
I have tried alcohol but it just didn't seem to work quite as well.

don't ask me about 'sanitary' :]
not a major consideration to me, frankly...
