leaf beetle life cycle - Lema daturaphila

leaf beetle life cycle - Lema daturaphila
Hudson, Hillsborough County, New Hampshire, USA
July 30, 2005
Size: 7.5 - 8 mm
Found a few on several of the host plants, along with larvae and eggs I suspect are theirs. Beetles did not attempt to fly or drop from plant when examined or collected. I suspect they are protected by chemicals from the host plant, which would account for their bright atire. Also, since plants tend to grow on bare sandy soil, dropping off the leaf would do little to protect the beetle. This beetle squawks noisily when molested. Notice bright orange-red abdomen showing under partly spread wing covers.

ID confirmed by S.M. Clark: probably Lema daturaphila

Lema trilineata
Three-lined potato beetle, Lema trilineata. Assuming you're correct as to the ID of the eggs and larvae--and http://www.dirtdoctor.com/view_question.php?id=713 has a description that matches these photos--then very nice images of the full life cycle!

 
Hmmm
You'd think I would recognize it at once since four prior images for the species were contibuted by me! Thanks!

 
:- )
I've spent hours trying to ID a specimen before realizing it I'd just compared it with those in my collection....
