Fusion between human and parasitoid wasp. Vespicable vary in proportion with their component wasp species, with smaller varieties capable of sustained flight and larger Vespicable able to at least leap and "parachute" an impressive distance. Their venom attacks the brain of prey, disabling defensive instincts and leaving the victim totally compliant to the monster's wishes. Females take this opportunity to encase the victim in a beautiful but sturdy casing of mud, wood pulp or other detritus held together with dried mucus, storing the meat for later or entombing it as nourishment for the monster's offspring. Human children are especially favored as hosts due to their convenient size, giving the Vespicable a mythical bogeyman-like status in primitive communities.

   Some Vespicable are derived from social wasps, in which case a reproductive "queen" will control numerous non-reproductive drones. Queens tend to take on a slightly more human appearance than normal Vespicable, especially in the face and upper torso.
