Variations of Harmonia axyridis
Observed in the Pacific Northwest

The Asiatic ladybug comes in many different variations of pattern and color. Most commonly, the beetle is orange with black spots (up to as many as nineteen!) or it may be black with four red spots at the corners. Scientists believe that this "morphological plasticity" is one reason this lady beetle has been so successful.

These black and white drawings show the pattern variation observed in Oregon by Amy Dreves during July 1997 through July 1998.
