Definition of 'Hymenoptera'

noun

An order of insects including: bees; wasps; ants; ichneumons; sawflies; gall wasps; etc. [syn: Hymenoptera, order Hymenoptera]

From: GCIDE

Hymenoptera \Hy`me*nop"te*ra\, n. pl. [NL., fr. Gr. ? membrane-winged; ? skin, membrane + ? wing.] (Zool.) An extensive order of insects, including the bees, ants, ichneumons, sawflies, etc. [1913 Webster]
Note: They have four membranous wings, with few reticulations, and usually with a thickened, dark spot on the front edge of the anterior wings. In most of the species, the tongue, or lingua, is converted into an organ for sucking honey, or other liquid food, and the mandibles are adapted for biting or cutting. In one large division (Aculeata), including the bees, wasps, and ants, the females and workers usually have a sting, which is only a modified ovipositor. Hymenopteral
