Lifecycle of StylogasterA. Adult female of S. malgachensis Camras; notice the bent abdomen which the females flicks when hovering in flight (Rettenmeyer 1961a, Kotrba 1997); B. Close-up of terminalia from S. frauci Smith. Egg lodged in terminal chamber with anti-micropylar end protruding; C. Host location and ovipostition method unknown (Kotrba 1997). Confirmed hosts: Crickets (Gryllidae) and cockroaches (Blattodea); D. Egg attached to host. Anti-micropylar end is inside the host, extrusible sac and spines keeping the egg from falling off (2). How the larva exits the egg is unknown, the two proposed ways are illustrated (1 and 2); E. Larvae developing inside hosts; F. Illustration of Stylogaster larva, S. varifrons Malloch (Smith and Cunningham-Van Someren 1985). Whole larva in left lateral view. 2 Ventral view of anterior end showing antennae and mouthparts. 3 Cephalopharyngeal skeleton in lateral view and 4 dorsal view. 5 Posterior end of larva showing network of tracheoles in ventral view and 6 dorsal view; G. Larva exiting host from the end of the abdomen and pupating (Etzler et al. 2020); H. SEM of Stylogaster puparium, S. biannulata (Say) and close-up of I. posterior end, lateral view (Woodley and Judd 1998). The method of oviposition (C) and how the larva exits from the egg and enters the host (D) are still unknown, shown by blue arrows and question marks (?). Compiled from literature and based on (A, CS. malgachensis Camras, (B, DS. frauci Smith, (E, F, GS. varifrons Malloch and (G, H, IS. biannulata (Say), as all life stages from a single species were not availableModified from Smith (1967), Smith and Cunningham-Van Someren (1985), Kotrba (1997), Woodley and Judd (1998).
