Scolia nobilitata tricincta
Scolia nobilitata tricincta is a subspecies of digger wasp in the family Scoliidae. As a parasitoid of scarab beetle grubs, it locates white grubs beneath the soil surface, tunnels through dirt to reach them, delivers a paralyzing sting, and deposits an egg on the grub's skin. The larva consumes the living grub before spinning a silken cocoon to overwinter, emerging as an adult the following August. Adults are distinguished from the related Scolia dubia by having four yellow or off-white spots on the abdomen rather than two.
