Length 2-2.5mm. A small, mostly black ladybird with reddish-brown legs. Males have an orangey-red face and front edge to the pronotum, females lack the red colour at the front. The distinctive feature is the red tip to the rear abdomen. This can sometimes be seen protruding beyond the end of the wing cases, otherwise visible when the underside is examined. This feature can be hard to see on some of the darkest specimens. The larvae have pale bodies covered in thick, waxy white filaments, which make them look similar to mealybugs. 

Unless identified by a recognised expert, a photo is required and the specimen should be examined with a microscope. In the comments box, state the key or ID method used and describe the size and identifying characters.
