Xysticus cristatus is an ambush hunter which spends much time sitting still, with its fore-legs spread wide, waiting for insects to blunder into them. [3] In grass it adopts a flexible hunting position either at the tips of vegetation, such as flowerheads, or on the ground surface and as a result, the prey taken is varied and is made up of flying insects, including bees and butterflies.

Sidymella angularis (also known as the common square-ended crab spider), is a species of crab spider endemic to New Zealand. Like all thomisid spiders, this species does not make a web, but lies in wait for prey to appear nearby. It eats insects, or occasionally other small spiders. It lives in leaf litter on the forest floor or in low vegetation.
