Acmaeodera rubronotata
Acmaeodera rubronotata is a metallic wood-boring beetle in the family Buprestidae, distributed across Central America and North America. The species is one of numerous Acmaeodera species frequently encountered on flowers of yellow composites and other Asteraceae in arid and semi-arid regions. Field observations document adults visiting flowers of Heterotheca subaxillaris, Xanthisma gracile, Gutierrezia microcephala, and Heliomeris longifolia. The specific epithet 'rubronotata' refers to red markings on the pronotum.
