THE YOUNG 



NATURALIST.

Larva. — Brownish grey, and rather 

 mottled with redder brown. It has a num- 

 ber of black pointed warts, each producing 

 a stiff hair ; it often has pinkish spots and 

 marks, and is rather a pretty larva. 



Pupa. — Of the usual form, rather point- 

 ed at the tail, reddish brown in colour, and 

 buried under the surface of the earth with- 

 out a coccoon. 



Food Plants. — Oak is given as its 

 usual food, but it appears to live on almost 

 any kind of tree, and I have fed it in con" 

 finement on whitehorn, sallow and poplar. 



Times of Appearance. —The imago 



may be looked for from January to March 

 or April, the larva in May or June, and the 

 pupa may be found from July to the date 

 of emergence. 



Habitat. — Open woods or plantations. 

 Generally distributed throughout the 

 British Isles, but perhaps most abundant 

 in the north and west of England. Abroad 

 it is found generally in Central Europe 

 extending northward into Sweden, and 

 southward to the northern parts of Italy, 

 I'while it extends westward over France. 



Variation. — in the intensity of its 

 markings ^losaria varies considerably, the 

 wavy bands being often mere narrow lines, 

 and sometimes they can scarcely be traced ; 

 those nearest the body are generally the 

 'most distinct. -X- Only one form, has been 

 named, which is called Extinctaria, and is 

 less densely scaled than the type, the wings 

 nearly unicolourous and with few or no 

 markings. I have not seen this form, which 

 Dr. Staudinger gives as occurring on the 

 mountains of Silesia and in Siberia, but a 

 unicolourous form occurs in Yorkshire. A 

 speciman in my collection given me by Mr. 

 J. W. Carter of Bradford, and taken, I 

 believe, in Shipley Glen, is dark unicolour- 

 ous greyish brown, about the hue of the 

 darker markings of the type. This is the 



darkest specimen I have seen, but I under- 

 stand Mr. Carter and other Bradford col- 

 lectors have met with specimens nearly 

 black. 



• Since the above was in type, Mr. Mosley fnforms me 

 he has obtained, for figuring in his Varieties of British 

 Lepidoptera, a specimen of this insect with the bands 

 distinctly defined.
