Chilocorus similis is a species of red-spotted lady beetles belonging to the family Coccinellidae, subfamily Chilocorinae.

It preys on scale insects living on Euonymus species.

The elytra are brown-black, with two reddish round spots.

It measures about 3–5 millimetres (1⁄8–3⁄16 in) long.

This lady beetle was deliberately introduced to the United States by Marlatt in 1902 to control the San Jose Scale, an early example of biocontrol.
