BRITISH APHIDES. 



With the exception of the three oak species and the 

 single denizen of the willow, all the known British 

 Lachninse are feeders on Coniferse. Of these, some 

 affect the bole of the trees not far from the ground, 

 whilst others confine themselves very much to the 

 higher branches and are difficult to reach. 



In order to balance the heavy bodies of these insects, 

 they possess broad expansive wings, which if not 

 adapted for swift flight, are still well suited for floating 

 in the air, and thus they are the means of transporting 

 the alate male to vast distances by help of the changing 

 winds. 



Apterous males have been obscurely indicated by 

 Bonnet and De Geer. Koch also saw long narrow 

 green forms amongst the leaves of certain fir trees, 

 which he regarded as males. 



Many of the larger kinds of Lachnus furnish an 

 intense red stain when crushed, but the elaboration 

 of this dye-like juice is not confined to the Lachninae.
