This moth flew into my apartment from outside, so I have no personal experience of its life history, but it is apparently well known in horticultural circles as the “Garden Rose Tortrix” because the caterpillar feeds on (among other plants) garden roses. Several tortricids resemble bird droppings, and this may be one of them, but it is also using the defence of “disruptive coloration” – two well-demarcated contrasting colours that have the effect of breaking up the shape of the moth.
