Avoid putting moths and butterflies in the same bottle with your other Insects because the wing scales from the moths can coat other Insects. Most collectors keep a special bottle for moths and butterflies if they collect them. When you preserve an Insect specimen just remember that you are doing it to be able to examine the characteristics that will be used to identify it. Insects are preserved either dry on pins or in vials of alcohol. Specimens that will shrivel like raisins should stay in alcohol.
Insects have different acceptable methods of pinning.
An Insect has two sides, but only one center. If an Insect is too small to pin then it is glued to a small paper triangle. The triangle tip is glued to the right side of the insect leaving the bottom uncovered. The triangle should be stuck on the pin. All Insects are mounted using special longer Insect pins.
