Taxonomic note
Scelio opacus was originally described by Provancher in 1887. The Scelio is part of the Scelioninae, which was formerly treated as the Scelionidae but is now classified within Platygastroidea. The genus is characterized by its association with orthopteran .
Color pattern context
The Scelio is specifically noted in research on Hymenoptera color patterns as having common occurrence of the black-orange-black (BOB) pattern: black or dark , orange mesosoma, and black metasoma. This pattern has been observed across multiple biogeographic regions and is particularly prevalent in smaller of this group.
