• Your letter to the bugman    As of today, we went outside and found about 200 of these bugs in one small area in our yard. The have a beetle type body that is yellow with a black cross on them and a bright red head. They move very fast and dont die easily. I live in Phoenix and we have never seen them before. They are about 1 inch long, but some a little bigger or smaller. We have a baby almost here and I want to make sure they are not poisonous. I appreciate your help!
Thank for your help! Nicole

Iron Cross Blister Beetle

Hi Nicole,
Your letter is at least the third we have gotten in the past week requesting an identification for an Iron Cross Blister Beetle, though you letter is the only one that has indicated a high population density.
