SAWFLY (HYMENOPTERA: SYMPHYTA) RECORDING IN WILTSHIRE 1947-2000

diapause. In the spring the pre-pupa casts its skin 

 and metamorphoses into a pupa. This has external 

 antennae and legs and often moves. It is frequently 

 pale in colour but darkens prior to the emergence 

 of the adult which usually takes place within a few 

 days. In the case of the multi-brooded species, which 

 are usually small, the whole cycle takes takes place 

 in a matter of a few weeks. As a general rule the 

 smaller the species the quicker metamorphosis 

 occurs. This is, of course, only a generalised 

 description of the early stages, many species exhibit 

 individual variations which are dependent on a 

 variety of factors. 



WILTSHIRE SAWFLY 

 RECORDS 



In the list that follows species names are taken from 

 A Working Checklist of the British Symphyta 

 (November 2000) compiled by Dr D.A.Sheppard 

 of English Nature who is one of the leading 

 authorities on the group. The National Statuses 

 indicated are taken from English Nature's 

 environmental recording software package Recorder 

 2000, but it should be noted that no review has 

 taken place since the late 1980s, and even at that 

 time many species of sawflies were listed as 

 "Unknown". 



The Records column shows two figures 

 separated by a plus sign. The first figure is the 

 number of records made by Sir Christopher 

 Andrewes (1896-1988) between approximately 

 1947 and 1978. Sir Christopher, who was one of 

 the discoverers of the influenza virus and Director 

 of the Common Cold Research Unit, was also an 

 eminent entomologist and lodged 395 records of 

 200 species of Wiltshire sawflies mostly from the 

 Salisbury district near his home. His main interests 

 were in Diptera and Hemiptera, and only to a lesser 

 degree in Hymenoptera , which explains the small 



Family PAMPHILIIDAE 



Pamphilius fumipennis (Curtis, 1831) 

 Pamphilius hortorum (Klug, 1 808) 

 Pamphilius sylvaticus (Linnaeus, 1758) 



Family ARGIDAE 



Arge ciliaris (L.,1767) 



Arge cyanocrocea (Forster, 1771) 



number of records. The bulk of his collections, 

 which amounted to more than 18,000 insects, were 

 acquired by the British Museum (Natural History) 

 with the residue being distributed between several 

 provincial collections. No attempt has been made 

 to validate Sir Christopher's determinations. 



The second figure in the Records column is for 

 the records from 1980 onwards of which there are 

 566. During this period occasional visits were made 

 to Wiltshire by professional entomologists and in 

 1 998 the author and several others observers began 

 to record sawflies more widely across the county. 

 All recent records have been either referred to 

 experts for determination or compared with 

 reference specimens. 



The final column indicates distribution 

 according to lOKm squares of the National Grid. 

 A map of the Wiltshire 10km squares is included 

 below (Fig. 4) to assist in interpretation.
