This species is common in many parts of Europe, but is 

 not found in the British Isles. It expands from i to i^ 

 inch. 



It has light brown antennae, an ashy-grey head and thorax, 

 and a brownish abdomen with a blackish-brown anal tuft. 

 The fore-wings are ashy-grey, clouded with darker. At the 

 base is a blackish-grey waved transverse line, then comes 

 another nearly straight, and a third, which is somewhat waved, 

 approaches the second at the inner margin. Between these 

 two lines is often a blackish spot. The hind-wings are whitish 

 with a faint blackish-grey transverse stripe, which is some- 

 times broader at the anal angle. The fringes are chequered 

 with dark and light grey. 



The eggs are yellowish-white, with a blackish central dot, 

 and are covered by the female with the anal hairs. 



The larva is covered with whitish-grey hair, bluish-black on 

 the back and whitish on the sides, with two tubercles on each 

 segment, bearing reddish-yellow or pale grey hairs. It feeds 

 on oak from May till the beginning of July. 



The pupa is ochre-yellow, with two short terminal points, 

 and is enclosed in a firm reddish-brown cocoon, in which the 

 hairs of the larva are interwoven. 



The Moth usually emerges in about four or five weeks, but 

 may remain in pupa till the following year.
