Strongygaster didyma

Distinguished from other tachinid genera by the strongly convex scutellum. Separation from congeneric species requires examination of male terminalia and detailed chaetotaxy; S. didyma specifically distinguished by genitalic characters described in Loew's original 1863 description. Limited published resources exist for field identification of this species specifically.

As a member of genus Strongygaster, possesses a strongly convex, dome-shaped scutellum that projects prominently above the thorax. Body typically robust with the general habitus of Phasiinae tachinids. Specific coloration and body size for S. didyma not separately documented from congeners in available sources.

North America. Specific range details beyond continental presence not documented in available sources.

As a tachinid fly, functions as a parasitoid in terrestrial ecosystems. The subfamily Phasiinae is known to parasitize Heteroptera (true bugs), though this host association has not been explicitly confirmed for S. didyma specifically.

• Other Strongygaster speciesShare the diagnostic strongly convex scutellum; require genitalic examination for definitive separation.
• Other Phasiinae generaSimilar general body plan and parasitoid ecology; distinguished by the uniquely convex scutellum of Strongygaster.
