What are Hornworms?

Hornworms, also known as Tomato Hornworms, are the larval stage of the Manduca quinquemaculata, the Hawk Moth. They are known as the Tomato hornworm as when they are in the wild. Hornworms are viewed as pests because they feed on tomato plants and other garden variety plants. Hornworms in the wild tend to be green, whereas the ones we use as feeders are more of a teal/blue due to having a different diet.

Will hornworms give my pet diarrhea?

It is possible. This is a common question as hornworms are well known for having a high water content. As long as you are careful with how many that you feed and how big they are when you feed them, then you shouldn't have too much of an issue. If you notice signs of overhydration regarding your pet, then cut back on the hornworms.

 

What do hornworms eat?

In the wild, hornworms eat a variety of plants, but as feeder insects, a  powder mix is used, which is made from mulberry leaves and formed into a paste that is added to the cups that the hornworms arrive in so they can eat it. You can purchase extra hornworm food if you want some extra so you can keep them from running out. Since they grow very fast, they can run out if you are planning on trying to keep them for longer than a week.

 

How do I keep my hornworms?

When you buy hornworms, they arrive in a cup; a mesh will be secured to the middle of the container, which is used by the Hornworm to climb up and eat the food, which is a paste that is pressed into the top of the cup. All you need to do is keep them upside down so that their poop falls to the bottom in the form of small brown pellets that need to be cleaned out daily. Try to keep the lid where it will have ventilation so they will have some air. Hornworms grow VERY FAST, especially if they are kept warm, so if you want to try and keep them from becoming too big, then you will need to keep them somewhere cool that isn't the fridge, which is too cold for them. If they seem to be running out of food, you will want to feed them off, or they could die, you can buy extra hornworm food if this is a concern. See our guide on how to care for your hornworms for more detailed information.

 

How big will my hornworms get?

They will grow up to 3" or 4" if allowed to get to full size; depending on the temperature, this could be anything from a week to two weeks. They usually live up to 3 or 4 weeks before they either die or pupate into moths.

 

Does the "horn" hurt my pet?

The actual horn of the Hornworm is not hard; it is just for show to scare off predators and will not hurt your pet when the Hornworm is eaten. 

 

What will my Hornworm turn into?

Hornworms turn into the Hawk Moth. Generally, hornworms get fed off before they have the chance to pupate. However, if you kept a couple of weeks or longer, then you may notice your hornworms pupate. When they begin to turn, they will become a dark brown/red color and form a hard shell. Eventually, they will emerge as a hawk moth. This can be a fun project to do with your kids if it does happen. Unfortunately, you should not release the moth into the wild as they are considered pests, and this could upset the local fauna.
