The Enicospilus ramidulus complex comprises a cosmopolitan group of nocturnal Darwin wasps known for parasitizing the larvae of moths. Because of their striking, long-legged, pale orange appearance, many similar, closely related species were historically lumped together under the name E. ramidulus.
Key Identification & Biology Facts
Forewing Sclerites: Their wings feature two discrete, pigmented sclerites (the proximal and central sclerites) within the discosubmarginal cell.
Distinctive Coloring: The mesosoma (midbody) is uniformly orange-testaceous with no dark patches, but the metasoma (tail/abdomen) transitions abruptly to black from the 5th or 6th tergite onwards.
Nocturnal Behavior: Like many members of the subfamily Ophioninae, E. ramidulus wasps have large eyes and long antennae. They fly at night and are frequently attracted to artificial lights and porch lights.
Harmless to Humans: Despite their large, intimidating appearance and wasp-like classification, they do not possess stingers and are entirely harmless to humans.
