Hi,

I know people have different views on this topic and I don't want to start an argument! However, I have a few greasy specimens of tabanidae, asilidae, syrphidae, etc. which I thought I would try to "improve" by immersion in either of -

ethyl acetate, acetone or toluene ...

Some people advise acetone and it would seem regularly used with dragonflies, yet others dislike its use quite strongly.

Any thoughts?

Steve

I've always used ethyl acetate but acetone might be easier to obtain in shops. Do the anti-acetone people say why they don't like it? Does it leave a residue?

No, impossible that aceton leaves a residue. I think it is pretty practible
