Thyreodon atricolor

Thyreodon atricolor - A very distinct and large species with a black body, black wings, and orange-yellow antennae. Distinguishable as an Ophioninae by the laterally compressed abdomen with a distinct, circular "knob" between the first and second segments. Further distinguishable as a Thyreodon by the very large, bulging propodeum. Unlike most Ophioninae, however, the ocelli are very small and inconspicuous.(2) The basal tarsomere is just slightly shorter than the total length of subsequent tarsomeres, not slightly longer as in Therion or nearly twice as long as in Heteropelma (both Anomaloninae: Gravenhorstiini).
Food: Larval hosts: caterpillars of Sphingidae including Lapara bombycoides (northern pine sphinx moth), Lapara coniferarum (southern pine sphinx moth), and Paonias excaecatus (blinded sphinx moth)(2)
Life Cycle: Diurnal unlike most other Ophioninae, which are nocturnal.(3)
Remarks: "Although most members of the huge family Ichneumonidae are difficult to identify, this large species is an easily recognized, day active, slow flying parasitoid of sphinx moth caterpillars."
