Order: Araneae


All spiders feed on insects or other small arthropods. Most people are familiar with the common web-making species. However, there are many other spiders – wolf spiders, crab spiders, jumping spiders – that do not build webs but instead move about and hunt their prey on soil or plants. These less conspicuous spiders can be important in controlling insect pests such as beetles, caterpillars, leafhoppers and aphids.
