Identification
Adult: typical form has orange or red elytra with two black spots, and a black pronotum with white edges; other rarer forms range from all black to mostly black with red spots to mostly red with black spots, and the number of spots ranges from zero to ten (see links to photos in Internet References section below)
Range
Native to Europe and North America
"Its range in North America seems to be narrowing. Our greatest fear is that it's declining along with Coccinella novemnotata (C-9, the nine-spotted lady beetle) because of the same factors, and that it, too will soon disappear from large areas of its former range." [Danielle Martinez, Cornell U.]
Remarks
The markings on the pronotum are similar to those of Harmonia axyridis. However, the center of Harmonia's face (below left) is white, and the center of Adalia's face (below right) is black.
