Sawflies

Ian Andrews recently took over from David Chesmore as the sawfly recorder.  He can be contacted by e-mail at syrphus@hotmail.co.uk or by mail at:

24 Barmby Road, Pocklington, York YO42 2DP

 

There are 537 species of Sawfly in the UK, according to the 2014 Checklist of British and Irish Hymenoptera - Sawflies, 'Symphyta'.

 

Interest in Sawflies is growing and whereas in the past recorders have been limited to the keys of Benson, there is an increasing amount of extra resources to aid with identification becoming available recently, especially online.

 

R.B.Benson's three part key (1951-1958) remains the main port of call for identifying Sawflies and can be accessed via the following links...

Andrew Green has started up a  site for the Sawflies (Symphyta) of Britain and Ireland, with details of all species, photos of some, and maps for all. Usefully, it is already updated for the many recent taxonomic changes within the Nematinae. Access it here...

There is also an active British and Irish Sawflies facebook group, where a number of useful files can be accessed and help with ID can be sought. It can be accessed here...

I am interested in receiving all records of Yorkshire Sawflies. Please do e-mail me on the address above with any queries. I am happy to receive specimens for ID and I shall also collect records from iRecord. Be aware on the latter, though, that many sawflies cannot easily be identified from photos!
