Every spring when I put my tomatillos in the ground these guys show mating and laying eggs on the leaf undersides. I thought it was a Pigweed Flea Beetle -- via Edupic.com it appears the most similar -- but the stripe weights are reversed. My pest has much larger white stripes than black. Is this Pigweed or some other? thanks.
Hmm. I doubt the Pigweed. Check out: http://bugguide.net Great site. Click on the beetle image on the left side of the screen. Hours of fascinating perusal to be had! Good luck in your quest.
