Description

''Coscinia cribraria'' has a forewing which has a background colour of dirty white marked with black streaks along the wings and crossbands made up of dark dots, both of which vary in extent. The subspecies ''arenaria'' has an almost pure white forewing. The speckled footman has a wingspan of between .


Distribution and habitat

''Coscinia cribraria'' has a wide Palearctic distribution being found from Northwestern Africa Iberia and southern Great Britain east to China and Mongolia. In Europe, north of the Alps, the speckled footman is typically found on sandy heaths and open sandy pine forests. To the south of the Alps, it inhabits on dry mountain meadows with stony or rocky areas and around the Mediterranean this species can be found in habitats like maquis and in open forests.

'' are an important component of the habitat and larval diet of the speckled footman. In southern England the eggs are laid in June, mainly on ling and bristle bent with a few females being observed to oviposit during daylight hours. The eggs are laid high up on the stems of the plants. The caterpillars overwinter as larvae and pupate in the June following their hatching, creating rather flimsy cocoons among grass and heather. At altitudes of less than in this species' range south of the Alps the speckled footman is bivoltine with

Conservation

''Coscinia cribaria'' is common in the southern part ofits range but in northern Europe it is vulnerable to the destrucion of the open sandy heaths it prefers. In the United Kingdom it is classified as nationally rare meaning that it has been recorded from fewer than 15, or fewer,
