Hula nini?

It usually eats small insects and household pests that get caught in its web. If prey is too quick, it shoots web at it from a distance and then pulls the thread back in. Larger females can even attract baby skinks by hanging fly remains in their web.1

Ukweli

The assassin bug Stenolemus lanipes apparently feeds only on its young, though it can also eat adults.1

When food dries out, it usually drops it to the floor to free up space in its web, rather than rebuilding the web.1

It has poor eyesight and cannot detect movement more than three to four inches away.1

Males and females often share the same web for long periods, though females sometimes fight when they meet.1
