Ageniella (Ageniella) euphorbiae (Viereck)

CA: Amador County, Eldorado National Forest, Kirkwood Lake, hillside covered with boulders, elevation 2336 m; 30 July 2017; A. J. Abela. Host: Alopecosa kochi (Keyserling) (Lycosidae), juvenile, with all but forelegs cut off at coxa-trochanter joints. The wasp grasped the paralyzed wolf spider’s left foreleg midway from the end or the base of its right chelicera with her mandibles and walked forward on the ground, maintaining the spider dorsal side upward and keeping her wings flat on the dorsum. The pair disappeared into a crevice among boulders (Abela 2017).
