Melacoryphus nigrinervis
Black-veined Seed Bug
Melacoryphus nigrinervis is a seed bug in the family Lygaeidae, commonly known as the Black-veined Seed Bug. The species has been documented in Colorado during unseasonably warm conditions in mid-November, suggesting adult activity extends later into fall than typical for many temperate insects. It belongs to a genus closely related to soapberry bugs, though specific ecological details remain limited in published sources.
