Lesser Treble-bar
Aplocera efformata
(Guenée, 1857) 1868 / 70.193
Norfolk status
Much rarer than Treble-bar (A.plagiata).

Lesser Treble-bar is usually slightly smaller, with less intense dark cross-bands.
The most reliable way to separate the two species is by looking at the tip of the abdomen from below.

Treble-bar Male has a straighter, more pointed abdomen tip.
Female showing a distinctive tubular shape to the terminal segment of the abdomen.

Lesser Treble-bar Male abdomen is shorter and blunter, with slightly curved claspers.
Female abdomen blunt. This is less obvious and care should be taken.
