Darkling beetles, also known as mealworms and superworms, are one of the most common insect species on Earth. They belong to the family Tenebrionidae, which includes more than 20,000 species. Darkling beetles can be found in a variety of habitats, from deserts to forests and even in human dwellings. The life cycle of these beetles can vary depending on the species and environmental conditions, but generally, they undergo complete metamorphosis, meaning that they have four distinct life stages.
Egg Stage
Darkling beetles typically lay their eggs in damp soil or rotting vegetation. The female will lay up to 500 eggs at a time, which are white and oval in shape. The eggs hatch within 10-14 days, depending on the species and temperature.
Larva Stage
When the eggs hatch, the larvae emerge and begin to feed on organic matter, such as rotting vegetation, fungi, and even small insects. The larvae are often referred to as mealworms or superworms and can range in size from 1/2 inch to 1 1/2 inches in length. This stage of the life cycle can last anywhere from several weeks to several months, depending on the species and environmental conditions.
Pupa Stage
Once the larvae reach a certain size and age, they will burrow into the soil and form a pupa, or resting stage. During this stage, the larvae undergo metamorphosis and their body structure changes to that of an adult beetle. The pupal stage typically lasts about two to three weeks, depending on the species and environmental conditions.
Adult Stage
After the pupal stage, the adult beetle emerges from the soil. Adult darkling beetles range in size from 1/4 inch to 1 inch in length, and are usually black or brown in color. Adult beetles feed on a variety of organic matter, including fungi, decaying vegetation, and even small insects. Adult beetles typically live for several months, depending on the species and environmental conditions.

How Do You Get Rid of Darkling Beetles?
The best way to get rid of darkling beetles is to remove their food sources, such as decaying vegetation and organic matter, and to remove any potential nesting sites. Insecticides can also be used to control darkling beetle populations.
What Is the Difference Between Mealworms and Superworms?
Mealworms and superworms are both larvae of darkling beetles. Mealworms are smaller than superworms, typically measuring 1/2 inch to 1 inch in length. Superworms are larger, typically measuring 1 1/2 inches to 2 inches in length.
Do Darkling Beetles Fly?
Most species of darkling beetle do not fly, however, some species can fly short distances in search of food or shelter.
What Is the Difference Between Darkling Beetles and Ground Beetles?
Darkling beetles and ground beetles both belong to the family Tenebrionidae. Ground beetles are typically larger than darkling beetles, and have more rounded bodies. Ground beetles are also more active predators than darkling beetles.
Do Darkling Beetles Bite?
Darkling beetles do not bite or sting, and are generally considered to be harmless.
How Long Do Darkling Beetles Live?
The lifespan of a darkling beetle can vary depending on the species and environmental conditions, but generally, the adult stage of the life cycle can last several months.
What Colors Do Darkling Beetles Come In?
Darkling beetles typically range in color from black to brown, but some species may also be yellow or reddish in color.
Do Darkling Beetles Make Noise?
Darkling beetles do not make any noise, but they may click their mandibles when disturbed or threatened.
Are Darkling Beetles Poisonous?
Darkling beetles are not considered to be poisonous, but they may carry bacteria or other pathogens on their bodies.
