Strange Red & White Cricket (?)
Sun, Jun 21, 2009 at 9:07 AM
I am visiting my mom in Rio Rico, AZ (about an hour south of Tucson, AZ) and we found these strange looking red, white and black crickets (?) on a bean plant this morning (06/21/09). I’ve never seen anything like them, especially their antennae. Towards the end of it there is a flattened almost circular area, and then the straight line antennae continues. They seem to be feeding on the beans in the plant, and there must be 30-40 on one plant.

These are not crickets. Rather they are True Bugs, more specifically, Giant Mesquite Bugs, Thasus neocalifornicus, in the family Coreidae, the Leaf Footed Bugs. They are not feeding on beans, but rather the pods of Mesquite. These are colorful immature nymphs. Once they become winged adults, much of the bright coloration with distinctive markings is covered by the wings. You may read more about them on BugGuide.
