It belongs to the subfamily Nemognathinae, a group characterized by elongated maxillary mouthparts adapted for nectar feeding on flowers. The species is found in North America and is part of a genus known for its distinctive floral associations and capillary-based nectar uptake rather than true sucking mouthparts.
Nemognatha piazata bicolor
Nemognatha piazata bicolor is a subspecies of blister beetle in the family Meloidae, native to North America. It belongs to the subfamily Nemognathinae, characterized by adults with greatly elongated maxillary mouthparts adapted for feeding on nectar from deep-corolla flowers. The species is part of a genus notable for its specialized nectar-feeding morphology that functions through capillary action rather than true sucking.
