Black Triangle Moths - Genus Grammodes and others

Family Noctuidae, Subfamily CATOCALINAE

This page contains pictures and information about Black Triangle Moths in subfamily Catocalinae that we found in the Brisbane area, Queensland, Australia.
In the subfamily Catocalinae there is a group of moths which are dark brown to black in colours with white strips on wings. Some species have the eye-spot patterns on wings. When rest, they all hold their forewings in equilateral triangle shape. Those colours and shape make them do not look like a moth. We believed those Black Triangle Moths mimicking each others and form a Mullerian mimicry complex.
Not much is known about the caterpillars in this group.
