Hoverfly Det's results

I have received the results of the specimens I sent Roger Morris of the HRS in early November, which were specimens that I had gathered in the valley throughout 2016 and the results were better than expected. With 6 new species for the valley and many difficult species confirmed by determination rather than photographs.
