Insect Pins

[Jean Michel Maes]

Hi Doug,

I have had problems with some black pins (I do not remember the company),
mounting Carabidae. 6 months later the pin was completely rusted and the
insect fall, he litteraly eats the pin. I think those Carabidae were
collected with wine or vinegar.

I have used white pins with no problems. Will see in 100 years...

Bye,

Jean-Michel.
