ocellar

Ocellar structure is common; the ocelli consist mainly of orthoclase and quartz, and may be a quarter of an inch in diameter.

Ocellar structure is occasionally present, though less marked than in the camptonites.

Ocellar bristles: in Diptera, are situated close to the ocelli, usually directed forward: often absent.

Ocellar ribband: a crescent-shaped, smooth thin belt across the eye region in butterfly chrysalids.

Ocellar triangle: a triangle, indicated by grooves or depressions, on which the ocelli are situated; Diptera.
