Snail-killer

I don't think it is a Sciomyzid. Perhaps something like Lonchopteridae?

Clusiodes

Can you give an idea of what features led you to Clusiodes, please, John.

Thanks

Ian

Colour, shape and habitat.

Colour, shape and habitat. They are fairly small, chestnut brown (at least the commonest is, I've never seen most species of clusiid), slightly flattened, and stroll about on dead wood. I think the family has a single defining character, something to do with the antennae as far as I can remember, but not the sort of thing you can see in the field. You need to examine the male terminalia for a definite id to species. Alan Stubbs wrote a key to them about 1982.

Thanks

Thanks, John, that is helpful. I am just starting to key out a variety of flies to family using Oosterbroek but have not found one of these, yet
