Maybe a lacewing, they eat aphids if it is.

Might be a Grasshopper

Thanks but it looked more waspish ?  I've not seen anything like before

I think its a caddis fly. Could it just have emerged from your pond? as they spend their nymph stage as a favoured trout snack!

See if you can find you rescued insect from these:

https://www.naturespot.org.uk/ (https://www.naturespot.org.uk/)

There are a lot to look through.

A preliminary glance on the sawfly pages threw up Cephus nigrinus

https://www.naturespot.org.uk/species/cephus-nigrinus (https://www.naturespot.org.uk/species/cephus-nigrinus)

I don't think it is an exact match not least because it is listed as a stem boring insect. (although that may refer to its larva of course)

I doubt it is a garden nasty otherwise we would be able to recognise it better. :happy7:

Thanks Ed  . This seems to be the nearest ... https://www.naturespot.org.uk/species/rhogogaster-chlorosoma   A green sawfly ! should have let it drowned  ( in the water butt)
