Defensive display

Some of the species, such as Speiredonia spectans, S. cthulhui, S. hogenesi, S. martabanica, S. sandokana, S. alix. S. itynx, S. levis and S. celebensis have a pattern on the wings that while the moth is at rest looks like the 3-dimensional face of a lurking animal with eyes and nostrils. This pattern is more clearly discernible in females[3] and may cause an attacking predator to hesitate or perhaps withdraw.[4]
