#1 maybe some kind of ichneumon wasp

#2 a caddis fly i think

#3 looks like Mesembrina meridiana

#4 is a hoverfly, Rhingia campestris

(going by the labels in the thread (labels 2 and 3 are the other way around in the Gallery names))

1. Is a Braconid Wasp (Not a clue which there are loads.)
2. Limnephilus sp. Possibly L.rhombicus
3. Is definately Mesembrina meridiana
4. I agree.

Tons I'd say!

Generally, in my experience at least, they have heavier but more transparent pterostigma (the coloured cell on the leading-edge of the wing) and often heavier veins. The technical way is probably antennal segmentation, though! Wouldn't mind other views on this.

Take care,

Jason

Look at the wing veins. Look at the circle if this has got a vein from the bottom of it connecting to the vein below which leads to base of the wing its an Ichneumon. If this vein is absent its a Braconid. Size helps but isnt always reliable.
