Zeltus amasa

Fluffy tit

Its hindwings carry false eyes, antennae and legs that mimic a head, so an attacking predator strikes the wrong end while the butterfly flies off unharmed.

WhenJanuary to December

The fluffy tit is a small lycaenid. Males are black above with pale azure blue at the forewing base and across most of the hindwing, while females are plain pale brown. Long white tails, about twice as long at vein 1b as at vein 2, extend from the hindwing alongside false eye spots and antenna like markings that create a decoy head.

Caterpillars feed on all parts of the flowers of Clerodendrum laevifolium. Adults are most often seen at forest edges and along trail sides in brightly lit conditions, where males puddle on the forest floor.
