Beetles belong to the order of Cleoptera biologically. Cleoptera refers to having a wing shield, a characteristic also found in beetles. They have two pairs of wings - the soft ones that are used for flight and the hard ones which are used for protection.
There is a huge diversity in the types of beetle found throughout the world. They almost constitute 40% of the insect population of the earth. The oldest beetle has been dated back to around 290 million years. It was there even before the supercontinent of Pangaea was broken which means they are as old as dinosaurs or probably older.
Facts :
While all the other sense of beetles are quite weak, beetles can see ultraviolet light making their sense of seeing quite different from ours.
Diet :
There are many kinds of beetles present in nature. Some can feed on dung, some on fungi. The beetles are also known to feed on plants. Some of them also feed on other invertebrate insects. The feeding habits are more dependent on the kind of beetles.
Habitat :
Different species of beetles live in different kinds of atmospheres. Their need for temperature and humidity also vary. Moreover, the habitat needed for larvae is quite different from the habitat needed for the adult beetle. This means that extra care must be taken when creating a habitat for pet beetles.
Behavior :
They are quite territorial and dominating in nature. They fiercely protect their own small territory from any kind of intrusion. The female beetles can lay up to thousands of eggs and they take care that these eggs are laid near to a food source.
Like any other insect and animals, most of the beetles are territorial in nature. A male beetle can fight tooth and nail with other beetles to protect its territory. They do not have good sight, hence, the most of their communication is done through pheromones.
Lifestyle :
Beetles are quite active insects, but they are most active during their mating period. They behave differently before mating, like vibrating and transmitting that to whatever object they are on. Sometimes, their mating ritual is also marked with conflict and only one of them is left living after they mate.
Lifecycle :
Beetles go through four lifecycle stages: egg, larva, pupa, and adult. The females lay a good number of eggs on rotten wood or leaf but it is also important to know that some beetles keep their eggs in their system and give birth to larvae.
The egg hatches between 4 – 19 days. Secondly at the larva stage, these beetles eat a lot and shed their exoskeletons continuously. The pupa stage occurs during the winter period and lasts for over 9 months. Finally, the adult beetle emerges and mate. If the beetle is female, it will lay eggs and begin a new generation.
Predators :
Toads and frogs are known predators of beetles.
Breeding :
The first step to take in breeding beetles is to ensure that their larvae and adults are kept in the right environment. This means, proper temperature, space, humidity and food are provided for them.
Breeding commences as soon as you place a female and a male beetle in the right environment. Beetles are not parthenogenic. This means that a male beetle desperately needs a female to reproduce and they can be distinguished through several methods. However, it is easier to distinguish between males and females in adult beetles.
Some species of beetles are dimorphic and their males have big antlers that are used specifically for fighting. Females have no or small antlers and they have specific adaptations for burying their eggs.
If you own a terrarium in good environmental conditions, it will help the beetles deposit their eggs properly for hatching. Ensure that you remove the larvae as soon as the eggs hatch because grubs will eat the eggs when they find it difficult to get food. That is the best way to breed beetles.
Appearance :
Like all insects, beetles have a head, thorax, abdomen, and six legs. Their bodies are typically solid and durable, with two pairs of wings. The outer pair is notably harder than the inner pair.
Since there are many types of beetles in nature, it is difficult to define their size within range. Their size and weight is dependent upon the kind of species. There are microscopic beetles present in nature. There also are beetles which can measure around 20 cm.
Their color can vary a lot as well. Most of the time, the beetles are black in color. But there are beetles with bright colors as well. Bright green and bright red beetles make a kind of exotic pets. The body type of beetles varies as they age.
They start as larvae and then move on to pupae and finally to the beetle. Apart from this, they have six legs and mandibles to catch their prey. They also have antennas on their head, which help them to serve as an extended limb.
Life Span :
Generally, beetles live for less than one year. This means that, their four lifecycle stages lasts for less than one year.
Health Issues :
Surprisingly, beetles are hardly affected by diseases and this is a major plus for breeders. However, beetle larvae are affected by some diseases and parasites. Examples include black spot disease and this disease can be transferred from parents to offsprings.
These diseases can be controlled by keeping beetles in temperatures below 20 degrees Celsius. Affected beetles usually have blackish/brownish spots on their bodies. They should be isolated and treated.
Grooming :
Mutual body grooming exists between beetles. Individual beetles aid this process by being immobile and they do not change postures unnecessarily in order to facilitate the grooming exercise.
Shedding :
Beetles molt 5 – 60 times throughout their life span.
Beetles Characteristics :
- Beetles are the largest group of living organisms known.
- The history suggests that the first beetle-like organism appeard to earth 290 million years ago.
- Beetles vary dramatically in size. They can be from microscopic or giant.
- They are pests, but many of the beetles are useful in ecology as they help in breaking down waste products.
- They can be found in any kind of habitats from water bodies to land to plants.
- Some of the beetles chew their food unlike sucking them.
- Some of the beetles which lives on wood do not move at all.
- The female beetles give birth to thousands of eggs at the same time.
- The beetles make a lot of noise, some of which can be quite irritating.
- Beetles have several ways of communication, some of which include the excretion of pheromones.
- Beetles need different kind of habitat as they grow. The living place for larvae is not same as that of the adult beetle.
- Beetles are quite conflictive in nature, especially during their matingprocess. This results in death of one of the partners.

Beetles Information :
- Beetles belong to a group known as Coleopetra which means they have hard wings.
- They have a lifespan of less than a year.
- Most of the beetles are black or brown in color but they can be brightly colored too.
- They are a very diverse group. There are more than 300,000 species known to humans and many of other species are still undiscovered.
- Most of the beetles are active in night, but some of them can be seen in day as well.
- They have very strong sense of smell, which is used for discovering food and mates.
- Their size can vary from as small as 1 mm to 20 cm.
- They can be kept as pets, but they require special conditions and it’s needed to keep their habitat and nutrition similar to their original habitat.
- There is a whole industry that thrives on selling these exotic pets.
- Their price can vary from $10-$80 depending upon the type of species.
