Hawaiian Picture-wing Fly (Heteroneura)

A remarkable Hawaiian picture-wing fly famous for its hammer-shaped head, found only on Hawaii Island. Males use their broad, flattened heads in head-butting contests for mating rights. It breeds in decaying Clermontia bark.

💡

Did You Know?

Males have uniquely hammer-shaped heads that they use as battering rams, headbutting rival males in combat over territory and mates.

Lesser Bullet Ant

A large black ponerine ant found from Texas through South America with a powerful sting. It nests in tree hollows and dead wood, foraging arboreally at night.

💡

Did You Know?

It is sometimes called the 'false bullet ant' because its sting, while very painful, is less severe than that of Paraponera.
