Leaf Beetle - Griburius larvatus

Leaf Beetle - Griburius larvatus
Frenchman's Forest Natural Area, Palm Beach County, Florida, USA
June 18, 2004
It looks to be a species Cylindrical Leaf Beetle.

Moved from Griburius.

Griburius larvatus.
Griburius larvatus.

I agree..
it does look like Cryptocephalinae. I googled for a while and couldn't find one of matching pattern.

I'll check references..., plant?
I'll check Dillon and Leaf beetles of Alabama.
Beetles of Florida lists a bunch in that subfamily. Any idea on the plant? (Photo from further back.) That could be helpful.

I can get you another shot with more of the plant, no prob. However, it may not help much as these little dudes where buzzing around everywhere, I shot them on a variety of flora...

reference check--no further leads
I looked at that subfamily in Dillon (1) and in Leaf Beetles of Alabama. (2) I don't see any illustrations that are close in pattern, which is no big surprise, given the large number of species and the variability in pattern. The keys in Leaf Beetles (2) are very technical, and would require close examination of the clawas and ventral surface.

Part of Dillon's key (p. 671) says "pronotum no margined at base, sides crenulate" ---> Cryptocephalus. That fits this photo, but I'm not looking at the whole key, and there are likely to be many southern species not listed in that reference.

Griburius sp.
Hey Pat,

Check the first color plate of "American Beetles Volume 1"(1), it looks a lot like this fella. A quick surf also found this image...I think I am finally getting somewhere:)

Okay, the "Distributional Checklist of the Beetles of Florida" lists only 2 Griburius species with G. larvatus as endemic to Florida. I bet that's our critter...

Totally off subject here...
just read Ted and Jimmy....Moon Pie the first three of the Spiderwick Chronicles last Sat. while I ate an entire bag of chocolates :) (it was a great day) them all!

Aww shucks!
Thanks Lynette:)
