Dame. Host: Aphonopelma chalcodes , juvenile, approximately 20 mm in body length, with a single larva attached to the anterior dorsum of the paralyzed tarantula’s abdomen. The larva was allowed to continuously feed on the tarantula. Pupation occurred on January 30, 2020 . The wasp (sex unknown) emerged 90 days post-pupation. A series of photographs showed the larva on the tarantula, the pupal cocoon and the emerged wasp (Dame 2020; M. Dame, Tucson AZ, 2020 pers. comm.). AZ: Pima County, Tucson, Sonora Desert Museum; 10 November 2015 ; H. G. Byrne. Host: Aphonopelma chalcodes , juvenile, 22 mm (reared wasp, 21 mm ). A conscious juvenile A. chalcodes was found with the wasp’s egg attached to the anterior dorsum of its abdomen. Wasp larval growth and development on the host spider was followed through a series of photographs for 3 weeks as the larva fed continuously. Pupation occurred after 4 weeks. The exoskeletal remains of the spider, including urticating hairs, were incorporated into the pupal cocoon. An adult female wasp emerged 71 days post-pupation ( Byrne 2015 ; H. G. Byrne, Sonora Desert Museum, Tucson, AZ, 2017 pers. comm.).
