Hypolycaena erylus

Common tit

Newly hatched caterpillars of this butterfly are carried off by weaver ants soon after eating their own eggshell, beginning an association that lasts through their growth.

WhereMangroves, coastal parks and gardens
Size27 to 32 mm wingspan
WhenJanuary to December

Males are deep purple to shining blue above with a black patch of scent scales on each forewing, while females are dull brown with two large black spots crowned in white near the hindwing margin. Both sexes have two short, white tipped tails on each hindwing.

Caterpillars feed on a wide range of plants and are tended by weaver ants, which protect them in exchange for sweet secretions from a gland on the larva's back.
