Tricrania sanguinipennis, a flightless blister beetle that parasitizes ground-nesting cellophane bees (Colletes). Eggs are deposited near nest entrances and larvae latch onto female bees for transport down into brood chambers. Larvae can also attach to male bee, then transfer to female during copulation. #bee #beetle #insect #nature #entomology #Coleoptera #Hymentopera
