Figures 1–2 in First host record, nesting behavior, and taxonomic position of the spider wasp genus Hesperopompilus Evans and some other Evans genera (Hymenoptera: Pompilidae)

Figures 1–2. Hesperopompilus sp. (undescribed). 1) Female dragging a Eustala anastera (Araneidae), adult or subadult female, backwards across an exposed tree rootlet, grasping the immobilized orb-weaver spider by its left second coxa with her mandibles. The spider was held slightly above the substrate in a cephalothorax upright position. 2) Female in front of her nest entrance excavating a burrow in sandy soil using her forelegs alternately. She held her apical antenna segments against the floor of the opening and wings flat on her dorsum. Photographs © Yukioz.
