Description: One of our most common native ladybeetles, both the adults and larvae are predatory on aphids as well as a variety of other small insects. The adults and larvae can be found in a variety of habitats, wherever aphids occur in larger numbers.

Identification:  Rollover or tap pictures for tips on how to identify these predators. Adults: Oval, concave on top, flat underneath. Small, clubbed antennae. White 'bumblebee' shape on head, 2 white stripes that converge towards the back of the black thorax. Highly variable color and spotting pattern on abdomen. Larvae: Spiny alligatorlike bodies with an oval of orange spines on a blue-black abdomen. Legs that appear sharp and footless at the ends.

Value in Pest Management: Important contributors to pest management. Although these native beetles focus their attention on aphids, they are generalist predators and will consume other small insects and their eggs. The natural control they provide helps to suppress some pest populations. They are also the most widely sold ladybeetle for biological control of insect pests in North America (see BIRC online Directory).

Origin and Distribution:  Native, throughout North America (http://www.discoverlife.org/mp/20q?search=Hippodamia+convergens).
