Tobacco Hornworm For Bearded Dragons

Hornworms are the caterpillar larvae of the Five Spotted Hawkmoth. There are two types of Hornworms, both in the same family and both of similar appearance. The tomato hornworm is considered a major pest in the USA with the tobacco hornworm being less prevalent in the North.

The hornworm is so named because it has what appears to be a large horn at the rear end of its body. They feed on tomato plants, Aubergine plants (Eggplants), Tobacco plants, Moonflowers and potato plants.

Hornworms can be repelled to some extent by Marigold plants. Because Hornworms are considered to such a pest to the environment and farmers, do not ever just release Hornworms into the wild. If your bearded dragon does not eat them you should consider freezing them and then discarding them into the bin rather than releasing them.

Can Bearded Dragons Eat Hornworms?

Bearded dragons can eat hornworms. They have a reasonable nutrition profile, however, similar to Earthworms they do have a significant moisture content which can lead to over-hydration and diarrhea. They’re also quite likely to be more expensive to purchase than Earthworms.

Hornworms tend to only be available in the United States and/or Canada. We’ve certainly not heard of anyone in the UK feeding their bearded dragons on Hornworms and further research indicates that they are forbidden in the UK.

Hornworms do have a reasonably decent level of Calcium in them with minimal fat, almost no ash and a reasonable protein profile.

How Should I Feed Hornworms To A Bearded Dragon

Hornworms can be fed easily to a bearded dragon. They’re relative slow, nice and wiggly and stimulate your bearded dragons feeding response nicely. Their colour will contrast nicely with light flooring tiles or light coloured food bowls.

If you substrate is loose (such as play sand or sterile topsoil/playsand mix) then do not feed hornworms directly in the vivarium. Your bearded dragon could do without ingesting large amounts of sand or soil along with its hornworm.

Most people though will feed hornworms on the floor of the human living area. Often, this will be done by placing the brightly coloured wiggly caterpillar as far away from the bearded dragon as possible. Since they’re quite slow, but brightly coloured, they elicit quite the hunting response from your bearded dragon who, once they spot the caterpillar, will usually run as fast as they can and grab the hornworm. Be prepared for a bit of a mess though. Hornworms often explode in a nasty jello like catastrophe that your bearded dragon will have no interest in cleaning up for you.

How Many Hornworms Should I Feed A Bearded Dragon?

Although hornworms are quite nutritious, they can be relatively expensive and the amount of moisture in them relegates them to the ‘Occasional’ pile of Bearded Dragon food. Many dragons love a nice hornworm nosh now and then though so you can probably feed one or two a week without too much drama.

Just beware that too many will likely lead to runny poos and a big mess to clean up in the vivarium.

Can I Feed Dried Hornworms To My Bearded Dragon?

I’ve been unable to find any supplier for dried hornworms. I suspect because they are so much moisture content it would take too many hornworms to provide enough material and would be economically unviable.
