How to Cultivate Hongkong Caterpillar

Hongkong caterpillar is widely used as a bird feed, fish, reptiles and other pets. If you have some pets that eat Hongkong caterpillars, it makes sense to cultivate them yourself. Starting a Hongkong caterpillar farm is not as expensive as you think, and you can start and run it in no time.

Preparation needed

1. Gather equipment:

  • Oatmeal / dried oatmeal.
  • The source of organic moisture is not moldy quickly. Carrots fit, but you can also use fruits and vegetables such as sliced or chunks of potatoes or apples.
  • Three plastic jars with air holes on top.
  • Some cartons of egg cartons or toilet paper.
  • Hongkong caterpillar, also known as darkling beetle larvae. Start with 1,000 heads.

2. Pour oatmeal until the layer is as high as 2.5 cm from the base of the plastic jar. This layer became the base and food for this Hongkong caterpillar in several stages of growth.

3. Store a few pieces of vegetables in each jar. You can use fruits or vegetables such as celery, lettuce, potatoes or apples. Carrots take longer to mold than fruits and other vegetables. If you decide on vegetables or other fruits as a source of other moisture, make sure you often replace them.

4. Put Hongkong caterpillar into one of the jars. Some Hongkong caterpillars farmers also include a few pieces of bread and cereal or dried dog food into the jar. Put some pieces of cardboard on top of oatmeal.

6. Give appropriate label jars. One of them is for caterpillar (larvae), one for pupa (cocoon), and one for an adult beetle.

7. Close the jar and place it in a warm and dark area. Warmth will accelerate the process of caterpillar growth, so caterpillars will become pupa (pupa) faster when living in warm areas.


1 Keep the jars regularly.
  • Some breeders check every day, and some once a week.
  • Remove rotten vegetables, dead insects or mushrooms in oatmeal.
  • Add vegetables or oatmeal when needed, and stir the layer to avoid the growth of the fungus.

2. Note the pupa inside the caterpillar jar.
  • Depending on the temperature and age of the caterpillar when you buy it, the change to pupa may occur between a week to two months.
  • Caterpillar maturity at each stage of the cycle is marked by its dark color.
  • The pupa starts from a very pale white color and looks more like a curled beetle rather than a caterpillar.
  • You will notice that the caterpillar changes the skin several times before it turns into a pupa. This is normal.

3. Separate the pupa directly as you find it.
  • You can use tweezers when you feel disgusted.
  • Pupa does not move much and does not require any food at all. Moisture in the form of vegetables or fruits may be added in a jar, but pupa will not eat it.
  • It is important to separate the pupa from the larvae and the beetle because the pupa cannot defend itself and run away from the risk of being eaten before the cocoon is open.
  • The pupal stage lasts from one to several weeks depending on the temperature. You will realize it because the closer the time is open the color will be dark.

4. Keep checking the jars regularly for viewing
  • growth. This becomes even more important when you have more beetles in the cycle.

5. Move the adult beetle from the pupa jar directly as you find it.
  • They will start eating another pupa if not immediately moved.
  • Enter the adult beetle into a different jar with the same setting as the caterpillar. You can add more oatmeal to give you plenty of room to nest.

6. Check the jar of regular mature beetles and find the eggs.
  • Eggs will increase with the addition of beetles in the jar. Eggs can usually be found at the bottom of the jar.
  • You do not have to move the egg, but its existence indicates you will have larva (caterpillar Hongkong) soon.
  • The adult female will issue 500 eggs once to spawn.
  • Eggs will hatch in 4-19 days depending on temperature.

7. Move the caterpillar from adult beetle habitat into the caterpillar jar (larvae).
Because the females produce very many eggs you will often move the larvae when the eggs hatch.

8. Keep checking every day or every week.
  • Including replacing food and moisture sources (fruits or vegetables), keeping the beetles separated according to the stage of development, discard dead and randomly blocked oatmeal layers regularly.
  • If you notice that you have produced more Hongkong caterpillars than you need to feed your pet, grab some adult beetles and release them into natural habitats far from where you cultivate them. You can also give pupa as adult beetle food, or place more caterpillar in a bird feeder in your yard for wild birds.


  • Remember to replace old and moldy foods with fresh and fresh foods.
  • If you have fewer caterpillars, you can store them in a smaller jar
  • Saving caterpillars in the refrigerator will slow their growth. So if you prefer to give your pet a worm than a beetle, keep the caterpillar in the refrigerator.
  • You can use this guide to maintain a large Hongkong super worm or worm, but do not store it in the refrigerator. Because these caterpillars are tropical insects, so they prefer the room temperature.
  • In order for the super worm to grow into a pupa, you must move it to a different jar
  • Try not to put too many caterpillars in a jar.
  • You do not have to clean the nest too often.
  • Keep the jars cool. Caterpillar likes it more.
