Chlorion aerarium

Introduction:

The Steel Blue Cricket Hunter is so named because the solitary females hunt crickets of the family Gryllidae as prey. Once she locates one, she stings it into weak paralysis and flies it or carries it to a simple burrow she excavated previously. She sometimes chooses to dig her own burrow from inside the entrance of a cicada killer burrow, oddly enough. The burrow may terminate in more than one cell (multicellular burrows may even be the norm). The female places several crickets in each cell, closing the cell with a plug of soil between forays. A single egg is laid on one of the victims. The larva that hatches then consumes the cache of crickets.
Life Cycle:

Size 0.75-1 inch (20-25 mm)
Sexual Dimorphism: yes but subtle, males tend to be brighter in color and larger
Metamorphosis: complete (egg, larva, pupa, adult)
