Can you tell me what this is?

I've got no idea what this is so any ideas would be gratefully received.

Thanks to Gordon who has identified it as a Hoverfly larva. And those on Wildaboutbritain who have confirmed it specifically as a Syrphid larva

Bug Safari

My new toy is a macro lens so expect to see plenty of wee invertebrates coming this way, some in focus when I get depth of field mastered. Here's some critters captured in Northumberland last weekend. Please let me know if you can ID the ones with a question mark by them.

Tetragnatha sp

Meta mengei

Wolf spider ...... don't worry, it's not to scale!

Alder Fly

Chironomid midge

Sawfly - ? ....nearly 500 species in Britain!

Hoverfly - Syrphus ribesii

.....an aphid eater extraordinaire, consuming hundreds in its two week larval state

Hoverfly - Melanostoma scalare

A big critter - Brown Hare
