2. Concerning a subset of flies noted for a scale-like cover at the base of their wings ; referring to Diptera with a distinctive lobe or flap shielding the halteres ; characterizing insects within a specific fly grouping defined by these unique wing structures
3. Associated with a fly family identified by membranous lobes that partially obscure wing bases ; indicating insects in which the balancing organs are shielded by calyptral lobes ; identifying a morphological trait common among certain calyptratae flies involving wing-root coverings

Etymology: Calyptrate comes from "calyptra," a Greek-derived term for a veil or covering, which botanists borrowed to name the hood-like structure that covers a moss's capsule or a plant's developing parts. The adjective is built by adding the English suffix "-ate," which forms adjectives meaning "having" or "provided with" a given feature. So a calyptrate plant part is one that bears such a covering. The word's usage in the sense given here, with membranous wing-lobes, reflects how the same idea of a veil or hood was applied across different groups of organisms. The source records a second route to the word through "calypter," a noun used for a similar membranous flap, which also takes the "-ate" ending. Both paths lead to the same adjective, describing structures that cover or flap like a veil.
