I don't normally kill insects but I was wondering what chemical your meant to put in it?
I have read Ethel Acetate is one of the best and fastest?

I use cyanid. It works very fast.

Go to the old forum. Plenty of information there.

I find the freezer works best if you have access to one.

For Lepidoptera, I just press them on the sides of their thorax,when I catch them with my net,and put them in envelopes,classically. It is the best and fastest and most practical method for me,when a collector is in the field and collects many specimens.
For Coleoptera,either freezing for a few hours, or ethyl acetate.
Here I should also add that some butterflies (for example Parnassius) and moths (e.g. Saturnia pavonia),although pressed on their thorax, are again active inside the envelopes after a few moments. For this,I always carry with me a small fridge(where I also put my food to eat it in the forest) so for such kind of leps to be in a cool and dark place and not to move in the envelopes(ok,the Parnassius will not get any defect if moving,but a Saturnia or an Aglia tau for example will loose hair ! -ok,the females of e.g. Aglia tau or Saturnia pavonia are active and collected only at night,instead of the males,but the fridge,although dark inside, is cool enough to keep them inactive ;-) ) -also,this way,I avoid drying of the small Lycaenids etc during hot summer collecting days. When I go home and need to spread for example the Parnassius firstly,I freeze them for a few hours to kill them. But usually,I spread firstly the smaller stuff(Lycaenids),as they really need to be spread when freshly catched,for a perfect mounting job.

I have been using this method for over 35 years now with no damage to the specimens at all and it saves carrying stuff in the field, all I have to take are my net, plenty of paper envelopes in a box and my son to catch the really fast ones. For larger specimens such as hawk moths I do use a killing jar but never in the field, a pinch to the thorax is so much quicker and easier.

As thanos, I pinched them and put them directly in enveloppes to avoid leps to lose their scales. Then I put directly the leps in the killing jars.
I noticed that in the tropics, if you don't "kill" them quickly, specimens seem to moisture more easily. As if they sweat in the enveloppe...

I use pressing the thorax for lepidoptera too. For Saturniidae like Aglia tau I carry a small siringe with me filled with ethyl acetate. One drop injected into the body and the moth is quiet, no need to carry a fridge with you.
At my light trap I use killing pots by paradox company and ethyl acetate. I have 11 pots that I use one after the other as moth need some time to fully die in it. ->www.insectnet.eu
