Caterpillar

This species has grey forewings speckled with black markings which vary in intensity (with the female generally more heavily marked than the male). There is usually a bold cross-shaped black mark in the centre of the wing which has been likened to the Greek letter chi (Χ) and gives the species its common name. The hindwings are white in the male, dirty grey in the female.
