The Blue-fronted dancer is a slender damselfly with a bright blue face, thorax and abdomen tip in most males, though some males are grey black instead and can switch between the two colours over the course of days. Females appear in blue, brown or greenish forms and lack the male's blue abdomen tip.
Adults perch low along muddy rivers and larger streams, where males defend short stretches of bank and mating pairs can remain joined for up to half an hour. After mating, pairs fly together for up to an hour before females lay eggs on floating or submerged vegetation.
