Scoliid Wasps are a parasitic wasp that uses beetle grubs to feed it own young, even going so far as to use the grub's own lair for a nursery.
Making use of work done by beetle grubs, female Scoliid wasps are not ashamed to cut corners and maximize reproductive success. Beetle grubs dig underground to feed and pupate. Females find a tunnel and sting the beetle larva inside, paralyzing it. She then lays a fertilized egg vertically near the grub's rear. The wasp larva, once hatched, will feed on the immobile beetle larva until it grows and pupates, emerging as an adult wasp in the spring. The beetle does not survive.
Male and female adults do not look identical to each other though their markings are similar. Males are more slender while females have a plumper abdomen. Both can be found visiting flowers presumably to drink nectar.

Note: An insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed above as they are driven by environmental factors (such as climate change), available food supplies and mating patterns. Grayed-out selections indicate that the subject in question has not been reported in that particular territory. U.S. states and Canadian provinces / territories are clickable to their respective bug listings.
Ant, Bee, and Wasp Anatomy
Antennae: Ants and Bees both have a pair of antennae on the head that senses their surroundings.
Head: The head contains the insect's compound eyes, antennae, and mandibles.
Thorax: Contains various vital parts such as the aorta and nervous system.
Abdomen: Contains various organs including the heart, gut, venom glands, and anus.
Legs: Ants and Bees have three pairs of legs attached to the thorax (center-body section).
NOTE: Ants, Bees and Wasps are part of the Hymenoptera order because they share many similarities.
