Anoplius splendens

(Dreisbach, 1949)

Anoplius splendens is a spider wasp in the Pompilidae. Laboratory studies have demonstrated that females exhibit olfactory learning , specifically learning to associate the odor of spider with the presence of suitable hosts. This cognitive ability enhances their in locating host microhabitats. The was described by Dreisbach in 1949.

Host Associations

spiders (Drassodes auriculoides) - prey/paralyzed for larval developmentSpecific identified in laboratory study; learn to associate host odor with host presence

Behavior

Females demonstrate olfactory learning capacity, associating chemical stimuli ( odor) with host presence. In laboratory conditions using a two-choice static-air , previously exposed to hosts in association with feces-conditioned filter paper showed greater tendency to visit and spend more time in chambers containing that stimulus compared to control wasps. This learned association improves host location .
