We ship 12 hornworms in a habitat that fully sustains their needs. There are on average 15 worms per cup to allow for some loss in shipping. They ship at a little over an inch long and will grow to 4" long.
They are perfect for the fussy eater and are known to be the 'magic trick' to end a reptile's hunger strike. Not only are they an enticing blue-green color but they are very high in water making them a great way to rehydrate your animal.
Keep the habitat with either the lid up or if upside down on a screen or grate so the worms get fresh air. If you'd like your worms to grow larger, keep them at 82°. Keep them at 55° to slow their metabolism when they're at the desired size (a wine cooler works great for this).
Shake out the yellow little 'kernels', these are the droppings and will build up quickly
Q. Who eats hornworms?
A. Growing and adult bearded dragons, leopard geckos, uromastyx, amphibians, tarantulas, and scorpions, but chameleons especially love them! They are high in calcium, low in fat, and have no chitin (exoskeleton) making them easily digestible.
Q. What is their nutritional content?
Calcium: 46.4mg/100g or 464ppm
Q. I want to take them out and feed them plants, what do they eat?
A. Although in the wild they eat plants in the Nightshade family, these plants contain toxic alkaloids that will build up in the worms and may harm your animals. For the same reason, you should only feed your pets cultivated hornworms, and not pick them from your garden.
Q. What will the worm change into?
A. They will change into a beautiful moth known as the Sphinx or Hawkmoth. The wingspan is 4 to 4.75" long!
Q. How big will they get and how long do they live?
A. 3" to 4" long and weigh 10 to 12 grams. They live two to three weeks depending on how warm the environment is.
Q. Will that horn hurt my animals? Should I remove it?
A. No, it's just a colored piece of flesh to deter predators, it's harmless!
Q. Last time my hornworms were big, this order they are tiny. What gives?
A. On very hot weeks we pick our hornworms smaller to ship. If you leave them at room temperature, on a hot day they will grow about one half inch a day. If you choose USPS Priority as your shipping method, it can take up to 5 days and we don't want your worms to be the size of thumbs and unusable when you receive them. If you leave them out of the fridge, they will very quickly grow to the size you'd like and then you can refrigerate them in a warmer spot of your fridge to halt their growth.
