Flabellate is a term used to describe certain insect antennae. The term comes from the Latin flabellum, meaning fan. In flabellate antennae, the terminal segments extend laterally, with long, parallel lobes that lie flat against one another. This feature looks like a folding paper fan.
Flabellate (or flabelliform) is a morphological form of antennae found in some insect groups with the Coleoptera, the Hymenoptera, and the Lepidoptera.
Flabellate is just one of many morphological forms of insect antennae. See also:
