Harmonia Adult with Rollover ID CharactersHarmonia Larva with Rollover Characters

Description: Both the adults and larvae are predatory on aphids as well as a variety of other small insects. The adults are extremely variable in their coloration so can be challenging to identify quickly.

Identification:  Rollover pictures with mouse for tips on how to identify these predators. Adults: Round, concave on top, flat underneath. Small, clubbed antennae. White 'bell' shape on head, 4 black spots and 2 white patches on 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: These non-native beetles are generalist predators, feeding on a variety of small arthropods in a variety of cropping systems. They clearly contribute to pest management. However, they are also pests of homes where they can aggregate in large numbers through the winter. They have also been implicated in the decline of native ladybeetles. They are sold commercially (see BIRC online Directory).

Origin and Distribution:  Non-native, throughout North America (
