BRITISH BUTTERFLIES AND MOTHS 



Common Rustic. — (Apamea secalis.) Of common 

 occurrence almost all over the country, and appears on 

 the wing in July and August. The green larva has three 

 lines of reddish down the back, and feeds on grass, rush, 

 etc. The imago is subject to great variation. A general 

 description might be brownish, reddish, or yellowish 

 forewings, with a light mark on each ; much lighter on 

 the hind ones. 



Light Arches. — {Xylophasia Uthoxylea.) No apology 

 is needed for introducing such difficult scientific names 

 in an avowedly popular book, as it is well nigh impossible 

 to place any reliance upon the EngUsh ones in the world 

 of insect life. Thus this plain yellowish-brown species, 

 with the dark body, ill-deserves the unpronounceable 

 Latin name with which it has been endowed. It is a 

 common enough species, and may be seen about in June 

 and July. It may be observed resting on gates, palings, 

 and similar places during the day. The larva feeds 

 upon grass-stems from October to the following May, 

 and is brownish-grey in colour, with a tinge of either 

 greenish or ochreous. It is dotted with black, and the 

 head, and some other parts, are of the same colour.
