Western Spotted Cucumber Beetle - Diabrotica undecimpunctata
Enumclaw, Forested Unincorporated King County, Washington, USA October 1, 2009 Size: 10mm
I found it near another beetle of the same kind and both where on dandelions in the middle of the field. It has the characteristic eleven spots...or twelve if you're counting them while the elytra are open for flight. I know they are destructive little guys, but they are nice to look at.
