Subfamilies

The family Oedemeridae is a cosmopolitan group of beetles commonly known as false blister beetles, though some recent authors have coined the name pollen-feeding beetles. There are some 100 genera and 1,500 species in the family,[1] mostly associated with rotting wood as larvae, though adults are quite common on flowers. The family was erected by Pierre André Latreille in 1810.

Characteristics

Oedemeridae may be defined as slender, soft-bodied beetles of medium size found mostly on flowers and foliage. The head lacks a narrow neck, the

elytra, the tarsi are heteromerous with bilobed penultimate segment, the procoxal
cavities are open behind and the procoxae are conical and contiguous.

Natural history

Oedemera nobilis

The

develop in dead stems of herbaceous plants.

Adults contain the

polyphagous pollen and nectar
-feeding, and diurnal in activity. In tropical areas, most are nocturnal and are attracted to light.

Evolutionary history

The oldest known member of the family is Darwinylus from the Albian aged Alava amber from the Escucha Formation, Spain, a basal member of the subfamily Oedemerinae.[2] Unlike living species of the family, the specimen was found with gymnosperm (suspected to be cycad) pollen on its body, suggesting that the family had a gymnosperm associated prior to switching to flowering plants.[3] Species of the extinct genus Ditysparedrus and extant genus Sparedrus belonging to the subfamily Calopodinae, are known from the Cenomanian aged Burmese amber of Myanmar.[4][5]
