Odontota scapularis
orange-shouldered leaf miner, orange-shouldered leafminer
Odontota scapularis, commonly known as the orange-shouldered leaf miner, is a leaf beetle in the family Chrysomelidae. The species is found across eastern and central North America, with records from Canada (Ontario) and numerous U.S. states. Larvae mine within leaves while adults feed externally on foliage. The species has been documented feeding on Apios americana (groundnut), a leguminous vine.
Pachyschelus nicolayi
Pachyschelus nicolayi is a small metallic wood-boring beetle in the family Buprestidae, tribe Trachyini. The species is characterized by its blue coloration without pubescent spotting, distinguishing it from the similar P. purpureus. It is known to breed in Apios americana (groundnut) and Wisteria frutescens (American wisteria), with adults active later in the season than the related P. purpureus. The species has been recorded from North America, though its distribution appears to be less well documented than some congeners.
