Butterflies, moths and other specimens that will break or become discolored if submerged in alcohol.

Please include a general submission form in a separate plastic bag to keep it dry.

 For best results, follow these packaging steps:

• If the specimen is alive, put it into a box or sealable plastic container and freeze for 2-3 hours to kill it.
• Gently wrap the dead specimen in tissue paper or napkins.
• Pack the specimen in a strong crush-proof box for shipping.
• Ship the specimen to the address on the submission form.
• More detailed sampling instructions can be found in HYG-2121-12, Submitting Insect Specimens for Identification.

The CWEPPDC does not examine vacuum cleaner bags or items containing body fluids or skin as the laboratory does not handle medical waste materials.
