Leaf Beetle on Tamarisk - Altica bimarginata

Leaf Beetle on Tamarisk - Altica bimarginata
Green River, Garfield County, Utah, USA
April 27, 2010
Size: 5mm long
I found these in groups, of about 20-40 adults, on young tamarisk on sandy islands in the middle of the river.

S.M. Clark says, "probably Altica bimarginata Say,...
"...although I would need to examine genitalia to be sure. The host is willow (Salix spp.), but the beetles are sometimes so common that they cover many other plants as well."

Moved from Altica.

 
Thank you
