Figures 1–8 in Host selection and nesting behavior of Nearctic trapdoor spider-hunting spider wasps (Hymenoptera: Pompilidae: Pepsinae, Pompilinae)

Figures 1–8. Trapdoor spider-hunting spider wasps and their hosts. 1) Calopompilus pyrrhomelas female, with wings raised dorsally, stinging an Antrodiaetus sp., probably pacificus (Antrodiaetidae), adult or subadult female, dorsal side upward, under its mouthparts, Pacific Crest Trail, Klamath Mountains, Trinity County, CA.

Photograph © Julia Pearson. 3) Aporus (Aporus) luxus female dragging an immobilized Antrodiaetus sp., probably pacificus, adult or subadult female, backwards across a gravelly path, dorsal side upward, grasping the tibia of its third left leg with her mandibles. The end of the wasp's metasoma is bent downward against the ground and used for added leverage, Oregon Caves National Monument, Cave Junction, OR.

Photograph © Richard Seaman. 5) Aporus (Plectraporus) hirsutus female dragging an immobilized Aptostichus simus (Euctenizidae), juvenile, dorsal side upward, backwards across sand, grasping the end of its right pedipalp with her mandibles, coastal relict dunes, Vandenberg Air Force Base, Santa Barbara County, CA. Photograph © Alice Abela. 6) Psorthaspis planata female attempting to pry open the silk, soil and debris trapdoor of Bothriocyrtum californicum (Halonoproctidae), using her mandibles and forelegs in unison, Santee, San Diego County, CA. Photograph © Gilbert Quintana. 7) Psorthaspis mariae female dragging Ummidia audouini (Halonoproctidae), juvenile, backwards across rough soil, grasping its abdomen with her mandibles, Ellijay, Gilmer County, GA. The wasp holds the bent end of her abdomen on the ground for added leverage. The partly open trapdoor flap is seen below the wasp and spider's abdomen.
