Flea Beetle

Description:

With the exception of the larger spinach flea beetles, these pests are tiny, measuring just a few millimeters long. Most species are dark colored, and many have a metallic shine. Flea beetles are so named for their ability to jump when disturbed; they have large hind legs that give them a surprising vertical leap. (About.com Insects)

Habitat:

Adult flea beetles overwinter in leaf litter, garden debris, or other sheltered places. As temperatures begin rising in spring, the adults emerge and locate suitable host plants on which they feed. Some flea beetles will feed on weeds until garden crops are available. (About.com insects)

Notes:

I have never seen these beetles in my location...these were found on a primrose-willow at the edge of our pond.
