Cotinis
Green June Beetles
Cotinis is a genus of flower chafer scarab beetles in the subfamily Cetoniinae, distributed throughout North and South America. The genus was erected by Hermann Burmeister in 1842 and contains approximately 25 species. At least two species, C. nitida (Green June Beetle) and C. mutabilis (Fig Beetle), are recognized as common agricultural and garden pests. Members are characterized by their distinctive flight mechanism where hardened elytra remain closed while membranous hindwings extend for flight, producing a bee-like appearance and sound.
Glischrochilus
picnic beetles, beer bugs
Glischrochilus is a genus of small beetles in the family Nitidulidae, commonly known as picnic beetles or beer bugs. The genus contains two subgenera with divergent feeding strategies: Librodor species feed on sap and fermenting plant matter, while Glischrochilus species are predators of soft invertebrates. Most species are characterized by black bodies with contrasting yellow, red, or orange elytral markings. The genus is distributed across North America and Eurasia and includes several agricultural pests.
