Our first example—the Muslin Moth—has light brownish-grey and semi transparent wings, the front pair of which have darker markings arranged as shown in the illustration. It is a common moth, and may be met with in July and August.
The caterpillar feeds on lichens in June. It is of a dull grey colour, with a yellow stripe down the back, and has numerous little tufts of light hair.
The Common Footman (Lithosia lurideola)
The fore wings of this species are of a leaden grey, with a bright yellow costal stripe which dwindles to a point just before it reaches the tip. The hind wings are very pale yellow.
The larva is black, with a reddish line on each side just above the feet. It may be found during May and June among the lichens of oaks, blackthorns, and firs, especially in the woods of the south of England.
The perfect insect flies during July and August.
