Hovering above zero

I've seen very hoverflies this year so far. I guess because the spring has been so cold. We have had several frosts over the last week which is playing havoc with blossom and especially my emerging asparagus.

Wednesday was warm and sunny and a walk along the river Cam to Grantchester revealed a few hovers - mainly Eristalis and Syrphus.

This one I found in the garden last weekend and is a new one for me. The shape, yellow scutellum and the fact the abdomen is longer than the wings make this Sphaerophoria scripta.

Here's to hoping the temperatures pick up soon!
