Help me identify this insect that just scared the living daylights out of us in the South West of the UK.

This looks to me like an Ichnemon wasp. If it's not an ichnemon, it's still most definitely a wasp.

The thing that's weird about Morsey's wasp is how short its antennae are but I don't know if that's significant or not....could it just be a young wasp?

I don't think it's a wasp - it's blurry but I think it only has one pair of wings. On the right picture instead you can see a lump below the wing that I think is a haltere - which would make it a true fly. So a quick google suggests a member of the Tipulidae, and perhaps something from the genus Ctenophora. If I had to guess then I'd say perhaps a female Ctenophora elegans. Male Tipulidae have a swollen end to the abdomen, like in the linked picture.

Here's a better link to a picture of a female. Pretty happy with that species, now.

I'm with cromagnon-- the abdomen also doesn't look anything like a wasp's abdomen, and the petiole (waist) looks far too thick for a wasp. The long legs are also more true fly-like. I think cromagnon's got it.

Raaargh. Misremembered what I originally typed. Yours is a female Ctenophora pectinicornis, not C. elegans. Totally harmless, by the way, unless you're a rotting log, and quite rare, if I'm right about the species.

I stand corrected, indeed the wings are wrong for a wasp.

I always thought that these were a crane fly.

Oh, I thought it might be a wood wasp, but it looks like cromagnon has it.

bz - they are craneflies; it looks as though not all craneflies look like daddy-long-legs, which was news to me.

That's Brit daddy-long-legs, the US ones being, I think, opilione arachnids.
