My younger sister and brother-in-law also notice that, seen from the angle in my picture, it resembles those finger puppets of mice - the two 'eyes' and the triangular shape like a mouse's head.
This moth spends three-quarters of its life cycle in a state of extreme reserve, first as a lonely little egg on a twig overwinter, then eating in purdah as a caterpillar, first in a flower bud, then in a leaftip sealed by its own silk and finally in a larger leaf treated in the same way; as a pupae it has the double shield of a cocoon made underground. But after all this extreme caution, it then comes regularly to light as an adult moth.
I made sure that mine was tucked away beneath a bush before coming in to broadcast its image to the world. The Lord preserve it from spiders, mice and other predators.
