Insects in Great Britain .

a few instances just exceed 3,000 feet. Crags break the 
slopes between 2,000 and 2,500 feet. Above the crags stretch 
peaty moors, which late in the year justify the dreariness 
attributed to them by Continental writers. 
The straths or valley bottoms are as full of flowers and as 
full of insects as the moors are poor in both. It is part of 
our purpose to set before the reader a contrast of the two 
conditions. For the rest we shall compare the conditions of 
Flower Fertilization at Clova with Flower Fertilization in 
Germany, the Alps, and elsewhere. 
Except on our first two visits we kept a count of individuals 
visiting, and the record shows more clearly than any lists of 
visitors the importance of the various species. 
The count may be summed as follows, the desirability of 
the various groups to the flowers being indicated by the 
type, the larger the type the better suited for fertilizing the 
flowers 1 : —

1 Large capitals denote decidedly desirable insects or groups of insects, small 
capitals denote desirable ; small roman letters denote indifferent, and small italics 
denote injurious visits. The grouping closely agrees with Loew’s classification of 
Anthophilous insects into Eutropous, Hemitropous, Allotropous and Dystropous.
