The Life Cycle of Hornworms: Understanding the Growth Stages

Understanding the developmental phases and life cycle of your pet's feeder insects is crucial if you own a reptile. The hornworm, a common feeder bug, has many advantages for your reptile, including a high moisture content and a balanced calcium-to-phosphorus ratio. The intriguing life cycle of hornworms will be covered in detail in this blog post, along with information on how to care for them and whether they are suitable as a feeder bug for your reptile at each stage of their development, from eggs to moths.

Stages of the Hornworm Life Cycle

1. Eggs

Hornworm eggs have a small, rounded shape and a greenish hue.
Time: After being laid, the eggs normally hatch 3-5 days later.
Maintaining temperatures between 75°F and 85°F and providing a clean, well-ventilated environment can promote healthy development.

2. Larvae

Caterpillar-like hornworm larvae have a brilliant green body and an outgrowth that resembles a horn on their back.
Timeframe: The larval stage, during which they grow quickly, lasts for around 2-3 weeks.

Feeding practices: Hornworm larvae consume a specific diet, usually commercial hornworm chow, which gives them the nutrients they need for development and growth.
To guarantee proper growth, take care to maintain ideal temperatures, humidity levels, and a suitable food source.

3. Pupation

Hornworm larvae develop a hard outer shell called a pupa and darken in color.
Approximately two weeks pass during the pupation phase.To help them develop into moths, separate the pupating hornworms from the larvae and put them in a container with a layer of loose substrate, such as coconut coir.

4. Adult Moths' Appearance: Adult hornworms are huge, vivid hawk moths when they first hatch.
Within a few days of their emergence, adult moths begin mating and depositing eggs.
Lifespan: Adult moths only live for a few days 8-12 days on average.
Provide the moths with a shallow dish of sugar water to feed on and a vertical surface to rest on.

Insect Feeders: Hornworms
For a variety of reptile species, such as bearded dragons, chameleons, and leopard geckos, hornworms are a great feeder bug option. They are a great source of calcium and protein, two important minerals, and their high moisture content keeps your reptile well-hydrated. To get the most out of utilizing hornworms as a feeder bug, make sure they are the right size for your reptile and that their guts are filled with a healthy meal.


Owners of reptiles who wish to give their animals the greatest diet possible must be aware of the hornworm life cycle and growth stages. You can raise hornworms that are healthy and provide many advantages for your reptile's diet by being knowledgeable about the care requirements at each stage. As always, it's critical to conduct thorough study on the species of your particular reptile to make sure that hornworms are a suitable feeder bug choice for their particular nutritional requirements.
