Meet the Namib Desert Beetle: Africa’s Tiny Survivor in the World’s Oldest Desert

The Namib Desert Beetle is a small animal that exists in one of the driest regions of the planet with the most unbelievable survival method. This beetle is found in the Namib stretching through the large and ancient Namib Desert where even the annual rainfall does not exceed one centimetre.

It is difficult to imagine that most animals would be in such a difficult situation, whereas this tiny insect has mastered the art of gathering water vapor and being cool in hot weather.

Namib Desert Beetle Habitat

Beetles comprise one of the most diverse groups of insects on the Earth. They are well distributed within the forests, grasslands, wetlands, mountains, and even the deserts. Others have been developed to survive in wet conditions and others can tolerate hot and dry places.

Most of the desert species which are the most inspirational to scientists inhabit along coastal dunes of the Namib Desert in southwestern Africa. It is an Atlantic coastal desert along Namibia and it is believed to be one of the oldest deserts in the world estimated to be more than 55 million years old.

Key Characteristics

These are some interesting facts about this wonder of the desert:

Appearance

They are usually black to be able to absorb the heat and have a large surface to cool.

Unique Adaptation

The most important aspect of the Beetle is that it is able to absorb water in the thin morning mist. Where there is hardly any rainfall, the clouds carrying the misty air of the Atlantic Ocean would be a salvation.

The back of the beetle has bumps and grooves which are specially made. There is an in-built water harvesting system which enables it to drink without need of rain or standing water.

Thermal Control

The beetle uses its long legs to move over the sand so that its body is approximately 15 mm above the sand with the heat on the surface to ensure its survival by not being killed by the intense heat.

The desert temperature can be more than 60 °C (140 °F) and extremely low at night. To adjust to these extremities, it quits the sand, races swiftly across hot areas, seeks refuge or excavates its graves.

Biomimicry

To improve water harvesting systems using biomimicry or learning to solve human problems, scientists are studying beetles to help them scale up their efforts. 

Based on the shell, engineers have come up with some materials used to collect fog, and even prototypes of a water bottle that can automatically refill itself with up to 3 liters of water per hour, which can be collected by air. They are testing these innovations in arid areas where the supply of clean water is limited.

Diet

The Namib Desert Beetle is a scavenger which preys on dead plants and animals and other organic wastes in the sand.

The Namib Desert is very sparsely covered with plants and therefore the dunes rely on wind-blown “desert muesli” as a source of food. It can also consume tiny insects and microscopic particles, and avail itself of any nutrient available in this harsh environment.

Size

This is a small and robust beetle. Majority of them are between 1 to 2 centimetres in length. They are miniature in size, which makes them energy saving and less water wastage.

Fog Harvesting

Fog harvesting is the strongest survival method used by the beetle. In the morning the dunes are smothered over with cool Atlantic fog, and the beetle flies to a high spot to meet the mist.

Its shell has small bumps that attract water (hydrophilic) and slopes that repel water (hydrophobic) which help in formation and rolling of the droplets that directly enter into its mouth. It exists without rivers or rain simply by absorbing water in the air.

The “Handstand” Method

The beetle is one of the most interesting creatures to have a handstand behavior.

It bends downwards, lifts the rear into the wind, and turns about and towards it. This orientation enables the collection of the droplets of fog efficiently on the back side of it. The rest is accomplished by gravity, which leads the water to its mouth.

Such a simple but powerful technique has popularized it all over the world.

Diurnal Activity

The Beetle is a strictly daytime insect, which is active in the day time even in the extreme heat of the desert. It exhibits special behaviors and physical adaptations that have helped it to outlive others who seek shelter in the sun unlike others who avoid sunshine.

Vibration Sensitivity

The Beetle is able to sense tiny vibrations in the sand. It feels the wind blowing on the dunes and this frequent exposes new food, and thus beetle can locate what it wants to feed on.

When to Visit

The Namib Desert can only be visited during the cooler seasons that is, during May to September. The weather of this season is more conducive to the explorer and the fogs are common along the coast.

The times of early mornings are particularly magic, and the mists are falling down across golden dunes.

Travel Tips

You are planning to visit Namib Desert:

• Carry plenty of water.
• Light weight, yet protective clothing.
• Use sunscreen and a hat.
• Travel with a local guide.
• Conserve environment and fragile ecosystems.

The deserts are not as inert as it looks like, but they have plenty of life and balance.

Conclusion

The Namib Desert Beetle is a great lesson that it is not the size that matters when it comes to survival, but rather it is the adaptation. This little insect survives in one of the most inhospitable environments on earth with the help of intelligence that nature made.

On the one hand, there is fog harvesting, on the other hand, there is thermal regulation, but the Beetle allows us to realize that sometimes the smallest animal can have the most significant lessons. Its plot is not only survival but innovation, hardiness and harmony with nature.

FAQs 

How does the Desert Beetle collect water?

To obtain water, the Desert Beetle uses the fog to lie on the necessary postures so that the drops will be gathered on its coarse back and flow into its mouth.

How large is the Desert Beetle?

It is commonly one to two centimetres long.

Is Namib Desert very dry?

Yes, 1 centimetre of rainfall may be discussed as one of the driest areas of the world.

What does Namib Desert Beetle mean to science?

Biomimicry derives its inspiration on the new water-collection technologies on its ability to gather mist.
