Cerioidini is a widespread tribe of around 222 species of hoverfly. Cerioidini are mistaken for wasps for which they are effective mimic. Cerioidini have antennae with a terminal style and have somewhat elongate and basally constricted abdomens, only slightly in Ceriana, but pronounced in most Sphiximorpha; and Polybiomyia, and extremely in Monoceromyia. Larvae live mostly within tree sap associated with tree wounds or putrefying pockets of water in tree cavities.
