A lip-like structure or edge, especially one found in insects or other small creatures.
From Latin flabrum, meaning 'lip' or 'brim,' related to flare (to blow); used in zoological terminology for mouth structures.
Flabrum is the technical term biologists use for the upper lip in insects, and it's just obscure enough that most people never learn it, even though insects with labrums are everywhere around us.
