Your insect is the larvae of the green lacewing. These are very beneficial insects for the garden. The larva eat lots of aphids and other pests like caterpillars on cabbage, potatoes and other plants in the garden.
The adults are lacy looking green flying insects. They also feed on pest insects but do not eat as much as the growing larvae. They can give off an unpleasant odor when handled.
Here are photos of lacewings and larvae - http://bugguide.net/node/view/140/bgimage?from=96
