SERICORIDAL—CARPOCAPSA. 157 



August to October in acorns, leaving them when they 

 fall, and spinning np in any crevice under moss, or among 

 rubbish, remaining in cocoon as a larva through the winter. 

 It has been known to spin up in old decayed galls of 

 Cynips lignicola. Occasionally also feeding in walnuts and 

 Spanish chestnuts. 



The moth sits during the day on the branches of oaks, or 

 hides in any hedge or other shelter beneath, and may 

 occasionally be beaten out and induced to fly. Late in the 

 day and towards dusk it flies freely around oak trees, 

 especially those situated in woods. Not usually found in 

 any abundance, but fairly frequent in oak woods throughout 

 the southern half of England to Oxfordshire and Bucks, and 

 in the eastern and western counties extending even to 

 Durham and Cumberland ; but records from the Midlands 

 are almost wholly wanting, and in Scotland there is only a 

 report of its occurrence in the Clyde district. In Wales I 

 found it in Pembrokeshire ; and in Ireland it seems to have 

 been taken in Donegal ; but it may reasonably be expected 

 to occur in any oak wood in these Islands. Abroad it is 

 distributed throughout Central and Southern Europe, 

 Sweden, Bithynia and Madeira.
