Abrostola triplasia

This is the description from South (1907) "The fore wings of this moth are blackish grey inclining to purplish and rather shining; the basal area is pale reddish brown, edged by a curved dark chocolate brown cross line; a reddish grey band on the outer area clouded with ground colour and edged above the inner margin by a dark chocolate brown curved line; raised scales on the central area and on the cross lines. Two oval reddish brown marks on the front of the collar have some resemblance to a pair of spectacles, hence the English name". The oddly shaped humped caterpillar is green, sprinkled with white dots; on segments 4, 5, and 11 are whitish-edged darker marks, and there is a dark line, also whitish-edged, along the middle of the back between segments 5 and 11. There is a white line on the back from segment 4 to the brownish head, and white-edged dark oblique lines on the sides of segments 6 to 11; the line low down along the sides is whitish with an ochreous tinge. A purplish brown form also occurs, in which the pale markings are ochreous tinged. ==Similar species==
