Hi there Erik-
The best reference I can find in a textbook to this technique is in Brian
Worthington Stewart's 1951 book, "Collecting and breeding butterflies and
The relevant passage is as follows:
"There are other ways of killing butterflies which are less satisfactory or
even out of the question with moths. If you happen to possess nimble,
sensitive fingers you do not really need to have a killing-bottle in the
field with you at all- so far as butterflies are concerned, anyway,
"pinching" is all that is required. During the three or four years that I
was collecting in Morocco and the Norethern Sahara I did not even possess a
killing-bottle. Ninety nine times out of a hundred a butterfly, once caught,
will make the process easy for you.
As you double the net after effecting a capture, most butterflies will fold
their wings together over their backs, flat. All you have to do is to
administer a sharp nip to the underside of the thorax, just where the wings
join the body. Use the nails of your thumb and second (long) finger. With a
very little practice it is possible to killl instantly and without damaging
wings, legs or antennae.
(BTW, I did not have much success with this technique when I tried it
myself- but then I was doing battle with a fairly hefty silkmoth which was
able to put up more of a fight than most of the Rhopalocera!)
Hope this is useful to you
