I've been looking at sawflies on an amateur basis since about 2015 and slowly building up my knowledge. I'm still stuck on many Euura species as you might expect. I verify as many records as I can on iRecord and am the County Recorder for Bedfordshire. I've also produced the www.sawflies.org.uk website for British and Irish sawflies, which is very much a work in progress and still needs many verified images of species.
