BRITISH BUTTERFLIES AND MOTHS 



flourish, the larva feeding upon clover, grass, and similar 

 plants from July to September. It is light ochreous- 

 brown, with lines of a darker tint down the back and 

 sides. The pupa is hidden in a brownish cocoon, and 

 this is, as a rule, attached to a grass-blade. 



Red Under wing. — {Catocala nupta.) A specimen of 

 this large moth at rest, with its lichen-coloured fore- 

 wings closed over its handsome black and scarlet hind 

 ones, is far different to the spread-out form of all four 

 wings. It is sure to arrest attention by reason of the 

 striking appearance of the hindwings, but is likely to 

 be passed by otherwise. Search must be made for it 

 adjacent to poplars and willows in the Eastern and South- 

 ern Counties during August and September. The deep 

 purple eggs, having a yellowish apex and whitish bloom, 

 are laid on the bark of the trees mentioned. The larva is 

 whitish-grey, with dark brovv^n markings, and is a night- 

 feeder. The brownish pupa is profusely covered with a 

 light-coloured powder, and is contained in a strongly- 

 made cocoon, suspended among leaves.
