When I went out to water this morning, I found these bugs EVERYWHERE! They seemed to avoid my plants (not much there to eat yet), but were covering the weeds. Thousands of them!! Can anyone help me ID them? Are they a threat? I tried to look them up online, but can't seem to find them. -About an inch long -Long and rather thin, but the back ("butt") is thicker than the head -greyish/white with black/grey spots (leopard printed, almost) -Appears to be wingless Thanks! Dana Oh...forgot to add, I'm in the prarie of New Mexico (not the desert).
