Our small hornworms are from .5 – 1.5 inches. We ship our hornworms with around 1 inch of food, which is enough to get small worms over 2 inches. Our Small cups contain at least 25 small live hornworms. The hornworm cups must be kept lid side down to allow the waste to fall away from the worms and food. Be sure to clean the cup out every day by taking the lid off and removing the waste
