Calypter
Lobes on the forewing of flies
From Wikipedia, the free encyclopedia
A calypter is either of two posterior lobes of the posterior margin of the forewing of flies between the extreme posterior wing base and the alula, which covers the halteres.[1]
The lower calypter is the proximal calypter (synonyms: squama (of some authors), tegula) and the upper calypter is the distal calypter (synonym: squamula).[2]
Species of the subsection Acalyptratae are noted for lacking calypters.[3]
