You can order hornworms from Great Lakes hornworm, Lindasgonebuggy or Mulberry farms. They are expensive compared to other insects, so if you need superworms too, you might order them all together and see who can give you the best price including shipping. The hornworms grow very quickly, so if they arrive at a length of 2 inches, they can quadruple in size [ girth , or fatness ] and double in length in a week. If your girl is sluggish, keep trying to get her to eat greens, they contain so many nutrients and can also help her to poo. Get her in the sun for about 45 minutes a day, too, but keep her in an area where she won't be frightened by other people or animals. By the way, the easiest way to get a reptile's mouth open is to get a stiff piece of cardboard, like from a cereal box, and gently wedge it in her mouth, always very gently.The dragon will open their mouth + you can slip the tip of the syringe in quickly. If you are using a syringe, use plastic, not glass in case she bites down on it. Try to get extra water in her, too.
