Found on a sticky trap - is it thrips?

I was looking through the flies caught on the sticky trap in my greenhouse. I came across this fella (rather dead and crushed, sorry). I just need to know if it is beneficial or not. Could it be a form of thrips? It is about 9mm long.

    Hi Isobel,

     

    FYI: thrips of 9 mm in your greenhouse would be worth calling the newspaper for. It would have been a veritable giant! Your big specimen is a hoverfly, a female of the genus Sphaerophoria, which often cannot be identfied to species level. Larvae of Sphaerophoria are aphid feeders, so you may consider it to be beneficial.

     

    Cheers,

     

    Paul
