The fan is a nice touch. Many moths and butterflies (including your red underwing moth) rely on surprise to evade attackers, with wings drab on one side and brightly colored on the other. When attacked, they take flight and the bright colors show, the change confusing predators until the lepidopteran makes its escape. I suppose the fan would have different colors on both sides.

Aposematic colors are also common and so effective that the tropics are full of mimicry complexes featuring several different butterflies all mimicking each other. Moths (especially tiger moths, if I recall), being nocturnal and hunted by bats who rely on sound, similarly give off "warning clicks" which are also imitated by non-poisonous species.

Here's a comma butterfly with wings closed.
