Larva apparently uuknown. The suggestion that it may 

 feed on Vacciniuni or Callima is reasonable — that which 

 makes it feed on fir-needles is quite otherwise ! 



This is usually a northern species ; it is very extensively 

 distributed in mountain districts, occurring from the sea-level 

 to a height of 4000 feet ; emerging earlier in the season in 

 the valleys, latest on the tops of the mountains ; always 

 found among heather, on mosses, moors, or mountain-heaths. 

 There are several isolated southern localities — as at Bagshot 

 and Weybridge, Surrey, and the New Forest, Hants, and I 

 was much gratified many years ago at finding it, in great 

 beauty, on the heaths of Woolmer Forest, in the same 

 county. It is not, I think, as yet reported from the seemingly 

 more suitable localities in the South-west of England or 

 from Wales, but reappears in the mosses and on the hills of 

 Cheshire, Lancashire, Yorkshire, Westmoreland, and Cum- 

 berland, and in plenty in Northumberland and Durham. 

 In Scotland it is common in suitable places throughout to 

 the Outer Hebrides, Orkneys, and Shetlands ; and in suit- 

 able localities all over Ireland, having even been taken on 

 the Hill of Howth, Dublin. Abroad it has an extensive 

 range through Germany and the Alps, Holland, Iceland, 

 Scandinavia, Lapland, and Western Russia ; and in Arctic 

 America.
