As well as a few orthopteran firsts for me this weekend around Pitt near Winchester there was also this impressive hornet mimic hoverfly. I've seen the slightly smaller V. inannis around Elton before but both species are moving northwards so perhaps this one will occur at home too. The Chrysotoxum species below is also new to me but I am not sure of the ID. It could be arcuatum but I don't know if it is possible to tell from the photo alone. Any help would be welcome.
