Kingworms (Zophobas morio)

Kingworms look
like big mealworms, but are not the same. The exoskeleton is supposed to be more
easily digestable than that of meal worms. Kingworms are much larger and do not
require refrigeration to maintain as do mealworms. I store them between 70-85
degrees.
Listed below is the method I use for raising kingworms.
Materials needed for culturing:
- Container with ability to isolate kingworms individually.
I use a
rubbermaid tacklebox with with two small holes drilled
over each
compartment for ventilation. You can also use an
embroidery floss box or
film canisters.
- Oatmeal for bedding.
- Sterilized rotted wood.
- Deep plastic container with lid for beetles.
- Container for adult kingworms.
- Carrot, apple, or potato. I use carrots as the apples and potatoes seem to
mold easily.
Procedure
- Place a light layer of oatmeal and one small slice of carrot in each
compartment of box or film canister. Then place one adult kingworm in each.
- Place in a warm dark area (78-85). I use an old food dryer. My kingworms
take 2 to 3 weeks to pulpate into beetles.
- At first the beetles will be white. They will rapidly turn reddish-brown
and finally black.
- Place beetles into a container holding 1 inch oatmeal, rotted wood, and a
carrot, apple or potato. The container needs a lid with holes for ventilation.
- Maintain warm temperatures. The beetles will mate and lay eggs in wood.
VERY TINY worms will be noticeable in 3 to 6 weeks. Keep
a fresh piece of carrot in the container. Don't remove old food unless it is
getting moldy as baby worms may be on it.
- Every 4-6 weeks I place the contents of the container the beetles are in
into a separate container. Add some fresh oatmeal to new container. Put the
wood and beetles back into the orginal container with fresh oatmeal and start
over.
- In the meantime the old bedding will contain the baby kingworms. Keep them
warm and in a ventilated container. Keep a fresh piece of carrot in the
container. After another 2 weeks as you are noticing them reaching sizes of 1
inch or so, sift out the baby kingworms and place them in fresh oatmeal.
I mist the wood in the beetle container very
lightly every 5 days or so. Be careful not too mist oatmeal as it
will mold.
Baby kingworms are great food for hatchlings!
Thanks to Don Stacy and Russ Frisk for their help and advice getting me
started.
