Physical Sample Submission of Caterpillars, Worms, Grubs, etc.
Include a completed Insect/Arthropod ID Request form in a separate plastic bag.
Caterpillars are extremely difficult to identify if placed directly into alcohol without following 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 70% 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.
Ship the specimen to the address on the submission form.
Caterpillars can also be shipped alive in a crush proof container with a few leaves or wrapped in a damp paper towel.
