Asian Ladybird Beetle

DESCRIPTION:

These ladybird beetles are about inch long, and orange with black spots. The spots may be faded in some, but they are similar in appearance to other ladybird beetles.

BIOLOGY:

(Harmonia axyridis) Adults and immature stages are beneficial because they feed on aphids. The eggs are laid in the spring and the larvae and adults attack aphids. There are 2-3 generation per year. Adults gather in large numbers to over-winter. The adults may live 2-3 years and return to the same wintering site.

SOLUTION:

Spray water on aggregations of the adults on the outside of the house in the fall. This may help to disperse them to other overwinter sites. Use a vacuum cleaner indoors to collect the adults.
