The colonies of Leptothorax acervorum are never very populous, 

 and it nests under the bark of tree-stumps oak and especially fir, 

 etc. but also under stones, where I have found it on the mountains 

 at Rannoch and Braemar. Parfitt states that this ant constructs 

 little runs by the sides of walls 16 , having found it in such situations 

 at Dawlish ; and I once discovered it at Fairlight, near the " Lovers' 

 Leap," in the cracks of a rock. It will also take advantage of the 

 borings of other insects, Tuck having taken it on a post tenanted 

 by the wasp Odynerus sinuatus* 6 at Norton Wood in Suffolk, and I 

 picked up a fallen " oak-apple " at Wey bridge on September 14th, 

 1912, which contained a small colony of L. acervorum consisting of 

 a dealated female, seventy-three workers and some larvae 64 . 



Andre says it is an alpine or sub-alpine species 18 , and Saunders 

 speaks of it as chiefly a northern species in Britain 17 , but it is 

 equally common here in the south. 



Forel points out that the alpine variety of acervorum is sometimes 

 nearly entirely brownish black in colour, and lives under stones 11 ,
