Crepidodera aereola
Crepidodera aereola is a species of flea beetle in the family Chrysomelidae, native to North America. As a member of the tribe Alticini, it possesses the enlarged hind femora characteristic of flea beetles, enabling jumping behavior. The species is among the smallest flea beetles in its region, with adults measuring approximately 1–1.6 mm in length. It has been documented feeding on plants in the genus Hibiscus.
Hypera quadricollis
hibiscus flea beetle
Hypera quadricollis is a minute weevil species in the family Curculionidae, historically classified under flea beetle genera Chaetocnema and Crepidodera due to morphological similarities. The species is strongly associated with rosemallow (Hibiscus spp.), particularly Hibiscus lasiocarpus, where adults feed gregariously on foliage. First described from Florida in 1878, it has since been recorded across eastern and central North America including Missouri and Alberta. The species was synonymized under Chaetocnema quadricollis by White (1996) in his revision of North American Chaetocnema, though current taxonomic databases list it under Hypera.
