Without antennae or antenna-like appendages; lacking needle-like structures or feelers.
From Latin 'a-' (without) + Latin 'cerasus' or from 'a-' + Greek 'keras' (horn, antenna). The negative prefix 'a-' combined with a root meaning antennae or horns.
Biologists describe insects with this term—but it's so old-fashioned that modern scientists would more likely say 'without antennae' instead!
