DISCUSSION 



There were 219 species of sawflies recorded in 

 Wiltshire between 1947 and December 2000. This 

 figure represents 43.7% of the British total of 501 

 species (although 9 of these are thought to be 

 extinct) . Sir Christopher Andrewes recorded 200 

 species in the first period and 104 species were 

 recorded in the second. 1 1 5 of the species seen in 

 the first period were not recorded in the second 

 and 19 species from the second period were not 

 recorded in the first. 



The extrapolation of information about faunal 

 changes from the comparison of such small data 



sets is liable to be misleading. It is expected that 

 the continuation of recording will produce records 

 of some of the additional species seen by Sir 

 Christopher, but perhaps not all. It would be 

 surprising if modern methods of managing the 

 countryside and climate change have not affected 

 sawflies as they have other taxa such as butterflies. 

 Some of the species recorded in the second 

 period deserve special comment. The Cimbex 

 connatus found by Henry Edmunds near Compton 

 Chamberlayne in July 1997 was the first British 

 record for many decades (Edmunds, H.A. & 

 Springate, N.D. 1998). The former pest species 

 Athalia rosae (Turnip Sawfly), now considered rare,
