Species Biology
Identification
Adult: 4mm to 4.5mm in length. In the typical form the base colour of the elytra is red, with two black spots at the centre. The pronotum is black with broad white edges leading from front to back. The white spot at the back of the pronotum varies in shape. It should be noted both the colour and pattern of the markings can vary greatly in this species, and there is even a dark form. However the legs are always black, a feature that helps with identification.
Larvae: The colour pattern is similar to the 10-spot, but the 2-spot is generally darker. However, it is difficult to separate the larvae of both species without considerable experience.
Adult habitat & habits
This species commonly overwinters in buildings, consequently it is regularly recorded indoors. It appears to be associated with riverside vegetation and gardens, but its precise habitat requirements in Ireland are poorly understood.
