Species Biology

Identification

Adult: 3.5mm to 4.5mm in length. Body is typically red with 10 black spots, but both the colour and pattern of the body can be very variable.  The pronotum is white with distinctive, but variable, black wedge-shaped markings. Legs are pale brown. 

Larvae: it is a similar pattern to the 2-spot but the overall colour is paler and it is more slender.  However, this is difficult to see without experience.  

Adult habitat & habits

It is associated with deciduous woodland edge and hedgerows

Diet

Feeds on aphids

Similar species

Adults can be confused with 2-spot, Harlequin and kidney-spot ladybirds. Can best be separated from the two latter species by checking that it doesn't have a 'rim' around the edge of the elytra.
