  • 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.
