Habitat : Cosmopolitan species. 



This species was known as the house-ant of Madeira, where it 

 was very abundant, and Heer wrote a very interesting paper on its 

 habits 2 . F. Smith records, in 1855, that this ant occurred some 

 years ago at Battersea 3 ; in 1858, its capture on a wall at Hamp- 

 stead, and in a hot-house at Exeter (Parfitt) 5 ; and in 1862 he 

 states it has been found in many conservatories, and in numbers 

 in a baker's shop in the Borough (Farren- W kite) 1 . Parfitt records 

 its occurrence in numbers in Mr. Veitch's nursery at Exeter n , 

 Saunders at Greenwich 12 , and Farren- White in an eating-house 

 in the City as well as in the baker's shop in the Borough ; he says 

 it is undoubtedly naturalized 15 . 



Typical Pheidole megacephala has not, however, been found in 

 England for many years.
