COMMON BRITISH MOTHS 



along the costal margin ; and, when at rest, scores may exist on a 

 single twig without being seen unless closely examined. The hind 

 wings are of a pale smoky tint, and rather glossy. 

 The larva is green, with black spots, and 

 feeds in May and June on the oak and other 

 trees, often almost completely devouring the

Peronea cristana 



This moth is not so generally abundant, but is very common in 

 many of the woods of the south. 

 It is remarkable for the large number 

 of varieties that have been observed, 

 many of which have been regarded 

 as distinct species. 



Its fore wings are of some shade 

 of brown or grey, with a light streak 

 of variable colour along the inner 

 margin, and a tuft of raised white 

 scales in the middle of the wing. 



It flies during August and September.

 LECHEANA. 



Ptycholoma lecheana 



Our last example of the family Tortricidcs is Lecheana, a moth 

 that is common in most parts in June and July. 



Its f re wings are brown, lighter towards the 

 base. There are no very distinct markings, but 

 there is generally a darker patch in the middle of 

 the wing, edged with a silvery streak on each side. 



The larva feeds on several trees, including oaks 

 and elms, in the month of May. 



Penthina pruniana 



The next family Penthinidce contains the 



FIG. 228. common species Pruniana, which may be readily 



PRUNIANA. known by its boldly marked wings. The basal 



portion of the fore wings, to the extent of nearly 



two-thirds of the whole, is very dark brown. The remaining third 



is almost white, and clouded with grey. The hind wings are smoky 



brown with a paler fringe.
