Orgyia Antiqua - Description

Description

See glossary for terms used

There is a striking dimorphism between the male and the female moths of this species. The male moth typically has orange- to red-brown (ochreous red and dark brown) wings; each forewing has a white comma-shaped (tornal) spot. He has marked plumose (short, bipectinate) antennae. The wingspan measures between 35 and 38 millimetres. The female moth has vestigial wings and is flightless; she is light grey-brown (ochreous grey), has "shortly bipectinate" antennae, and a swollen abdomen (de Worms, 1979; Waring et al., 2003). The caterpillar is distinctive (see images and below).

    To give an accurate description of what has never occurred is not merely the proper occupation of the historian, but the inalienable privilege of any man of parts and culture.
