Jeez I forgot how BIG hornworms get!! I got the "baby" hornworm cup a few weeks ago, and they were small enough to feed my pygmies, and now some are so large I don't think my panther and veiled can even eat them! As soon as they started getting big enough I've been feeding them off as fast as I can since I knew they get huge, but man alive! As long as my middle finger and fatter than my thumb all the way down. They made my young box turtles flee in terror when I offered them one! And I've seen them try to chase mice. Not pinkies, full grown field mice!
