Habitat. 



Formica fusca var. glebaria is widely distributed in North, 

 Central, and Southern Europe, also in Asia, and has been intro- 

 duced into gardens in Algiers 43 . Emery states that it does not 

 occur in the smaller southern islands in the Mediterranean, and 

 that it is absent from Crete, 30 but Wheeler points out that Krausse 

 has recently taken it in Sardinia 43 .

Formica fusca v. glebaria occurs in fields, on cliffs, etc., on the 

 Continent it lives in meadows and gardens, and Forster says it is 

 often to be found on the borders of woods. 



It nests under stones, in the sides of cliffs, etc., and frequently 

 constructs earth-mounds, which in fields are covered with grass.
