Mating Pile of Beetles?
Just found these guys shamelessly flaunting their group activities on our holly hedges. And in a family neighborhood, too. I don’t know what they are, but they are certainly colorful!
This is a aggregation of Florida Predatory Stink Bugs, Euthyrhynchus floridanus. Since there are both mature and immature individuals in you photo, we are relatively certain this has nothing to do with mating activity since insects have no interest in mating unless sexual reproduction is achieved. It is more likely this aggregation is based on either feeding or protection.
