APHIDES 



As far as I am aware, very few aphides have been recorded from 

 Sussex. Among these are some of the well known pests, such as 

 Siphonophora roses on roses, Phorodon hiimuH on the hop, Myzus cerast on 

 cherry, M. ribis on currant, etc. But there are others of more interest. 

 The/axes betiiUna, a species of a very small genus, has, I believe, only 

 been recorded from Guestling. The fine aphis Lachmis longipes is not so 

 remarkable for its long legs as for its very long wings, which exceed 

 those of any other British aphis ; it has been sent from Ewhurst. Dry- 

 obius roboris, from Guestling and Ore, has conspicuously mottled wings. 



Some of the aphides cause galls ; thus Pemphigus spirotheca forms 

 spiral galls on the petioles of the leaves of poplar, "tetraneura ulmi lives 

 in erect, often pedunculated galls on the upper surface of elm leaves. 

 Schizoneura ulmi, also on elm, causes the leaves to become distorted, pale 

 and bladdery. Chermes abietis inhabits conelike galls on the spruce fir, 

 while Phylloxera punctata, which is common, causes yellow spots on the 

 leaves of the oak and is nearly allied to P. vastatrix, the dreaded pest 

 of the vine.
