The adult mud dauber wasp captures prey such as an armyworm caterpillar. If the caterpillar is too large to carry back to her mud nest, she may tear off a bite size piece and return several times, until the caterpillar is consumed. She feeds the caterpillar bits to her larvae in much the same way a female bird feeds worms to her babies. These aquatic insects are great aerial acrobats. They catch small winged insects such as mosquitoes, flies or moths on the wing.
All spiders are predators.
They feed on a wide variety of insects and other invertebrates. All spiders spin silk, but not all spiders make a web to trap their prey. Some spiders are active hunters, such as wolf spiders, jumping spiders or crab spiders. Crab spiders have their legs directed forwards, so they resemble crabs. They are often brightly colored, and sit and wait on flowers for unsuspecting insects to visit.
