According to ecology records, lizards are natural predators of Tenebrio molitor beetles. And according to this study , they have some great nutrition to offer:.
Contrast these numbers with those of the larvae, mealworms:. In other words, mealworm beetles are higher in protein and lower in fat than the larvae, making them a leaner feeder.
According to ecology records, lizards are among the natural predators of Zophobas morio , too. Like mealworm beetles, superworm beetles also have a good nutrition profile:. Furthermore, the chitin of the mealworm beetle may be too hard for your pet to get his teeth into and this can put off a lot of leopard geckos from wanting to eat them. One thing that pet owner should bear in mind when choosing whether to use mealworm beetles as food is the smell of these insects.
Mealworm beetles are known for their pungent aroma which they use as a defense mechanism in the wild. Of course, if you are feeding live beetles to your pet, the beetle is going to attempt to defend itself and you will be left with the resulting odor. Moreover, you will want to consider the nutritional value of the mealworm beetle. For most leopard geckos and other small reptiles, the main part of their diet will be crickets with the occasional treat of worms and other insects.
However, mealworm beetles are not quite as effective in proving the same level of nutrition and so you should keep in mind that if you do decide to treat your leopard gecko to a few, it should be exactly that — a treat. That being said, they are preferable over some other types of foods that could be extremely high in fat such as wax worms.
It is never a wise idea to offer insects that have been caught in the wild to your pet. However, since wild mealworm beetles are known to eat foods that may have been treated with pesticides and other chemicals, offering them to your leopard gecko could make him rather poorly. While it can be tempting to go out and collect mealworm beetles if you live in an area where they are abundant, in doing so, you are running the risk of these insects not having as great nutritional value as they would if they had been purpose-bred.
When any insect or worm is bred with the intent of being used a pet food, they will undergo a process known as gut-loading, which is not nearly as torturous as it sounds. This process is when the insects are offered a diet that is high in calcium and other essential nutrients. This is primarily because at this stage, the beetles will not have developed the hard chitin that makes them so difficult to eat.
These can also be fed to your Bearded Dragon as a treat. However, they will often prefer mealworms before the transition to beetle occurs. Keep them refrigerated The simplest solution is keep them in a refrigerator. The mealworms prefer temperatures around 70 degrees, but you don't. At 70 degrees, this encourages the mealworms to consume rapidly, which then causes them to transition into the darkling beetle.
The duration of the pupa stage usually lasts around weeks. Once the pupa turns into an adult beetle it will reproduce and lay eggs until the life cycle ends and the beetle dies. You will need to separate any eggs or larvae from the beetles. If you fail to separate them, the beetles will eat them. They almost never fly I think I've seen it once and they can't climb plastic.
In all honesty, if you're dealing with a lot of mealworms, sometimes a worm can escape, pupate and turn into a beetle somewhere in your house. When pupae die and turn black, it's usually because the worms weren't given enough moisture with carrots or potatoes at the end of the larval stage. They need to store the moisture to last through pupation and will dehydrate and die if they didn't get enough. They are also very heat sensitive. Mealworms are the larval stage of the Darkling beetle insect.
While dormant, they are transforming into adult Darkling beetles. During this time, they do not eat. This stage will last for two to three weeks before hatching. Leopard geckos are commonly fed crickets, mealworms, superworms , waxworms, and feeder roaches.
Check out this breeder package including everything you need to breed your own mealworm beetles:. Mealworms will have to be in the breeder box for long. These worms need the right meals throughout their growth period to benefit your geckos. You need to draw up a list of vegetables to add to the box.
Carrots, spinach, and other veggies could be ideal for feeding your worms. Besides veggies, you need to add sweet potatoes every two to three days to nourish these mealworms. Glass breeder boxes are becoming common and allow breeders monitor their feeder insects easily. Finally, the breeder box should have smooth sides. Correct heating is everything when you need to harvest great mealworms for your geckos. Ensuring the right temperature will allow your mealworms grow as they should.
Use a heat lamp or well-positioned heat rock to boost heating in the breeder box. But it is important to consider moisture alongside heating. If your breeder box takes in too much heat, it could dry up and culturing may not happen as it should. After succeeding in setting up your mealworm breeder box, allow culturing to take place. If all factors are spot-on, your mealworms should grow from larvae to pupa within three to four weeks.
The pupa stage may not last as long before your mealworm beetles come to life. Recreating the right environment to encourage massive mealworm culturing is important. Consider using banana peels or other vegetables to retain moisture in the breeding box.
