I came across these insects on a hiking trail near our house April 12, 2015 , at the base of Superstition Mtn., Arizona. Lots of people hiking were wondering what they were. Their heads and mandibles remind me of an ant and they have 3 pr. of legs. All the insects were feeding on the same flower heads, which had finished flowering and were about to produce seed. I assume they were getting a high energy feed this way.
It seems we get at least one submission each spring asking for an identification of Iron Cross Blister Beetles in the genus Tegrodera. According to BugGuide: “Eriastrum [woollystar] is an important food source for all adults.”
