Insect of the Week – Crab spiders

Crab spiders

Last year, the focus of the Insect of the Week was crop pests. This year, we’re changing things up and highlighting the many natural enemies that help you out, silently and efficiently killing off crop pests. [note: featured Insects of the Week in 2015 are available on the Insect of the Week page] 

This week’s Insects of the Week are crab spiders. These are generalist predators, capturing any insects (small flies, ants, bees, wasps, beetles, small moths, thrips) visiting flowers, including canola which is in full flower right now. They are called crab spiders because they walk sideways like a crab.

For more information about these spiders, the other pests they control and other important crop and forage insects, see the new Field Crop and Forage Pests and their Natural Enemies in Western Canada – Identification and Management Field Guide for identification, life cycle and conservation options (download links for field guide available on the Insect of the Week page).
