Moth

This is a very small (1 cm) Moth with an orange face and dark antennae. They normally have a series of black dots running across the upper wings in a line. The last specimen was spotted on 13 June 2013 in the same place (playing dead), but only has 1 black dot. The underside is all white and very furry. When disturbed, they drop to the ground and feign death.
