A small distinct area, space, or compartment, especially in biological structures like cell patterns, seed coats, or insect wing membranes.
From Latin 'areola' meaning 'small space,' which itself derives from 'area' meaning 'space,' with the diminutive suffix '-ola' indicating something small.
Arioles help scientists identify and classify insects—the exact pattern of tiny spaces on a butterfly wing is like a fingerprint for identification!
