Caterpillars, worms, grubs, etc.
Caterpillars are extremely difficult to identify if placed directly into alcohol without blanching as they lose all color. For best preservation results, follow the steps below for blanching and shipping:
- Boil water (either in the microwave or on the stove) and remove from heat.
- Drop the specimen into the boiling water.
- When the specimen rises to the surface, scoop it out and place it into a leak-proof vial of alcohol (rubbing alcohol or isopropyl).
Place the container into a small box and pad the container to keep the specimen from being damaged during transit.
Include a completed General Form along with a check for the identification in a separate plastic bag.
Ship the specimen to the address on the submission form.
- More detailed instructions can be found in HYG-2121-12, Submitting Insect Specimens for Identification.
- Please note that caterpillars can also be shipped alive in a crush proof container with a few leaves or wrapped in a damp paper towel.
