There are about 7,000 known killer beetles in the world, ranging in length from 4 to 40 mm and sharing the same weapon – a pointed, curved needle-shaped structure known as “rostrum”. This is the weapon they use to stab their prey – usually other insects, and the killer also injects their prey with poisonous saliva to loosen their organs. When the victim stops moving, the killer beetle will begin to leap in and suck the fluid inside the prey’s body until only the crust remains. That crust is used by some killer bugs as “armor” in disguise. Biologists have also observed this phenomenon firsthand, moving with a pile of insect carcasses on its back.
Reduviidae, also known as killer bugs or killer bugs, is a family of insects consisting of bugs, they are parasitic bugs, which suck blood. They bite very painfully and when saliva is injected into small insects, the tissue will melt, then they will suck the liquid into the abdomen.
Just like its name, in order to reach prey, the killer beetle always attacks prey when the victims lose their guard. Some killer bugs are known to mimic the appearance of their prey and move so gently that they do not make any sound to approach their prey. Once within ideal distance, the killer bug will rush in and attack the victims with the “armor” on its back. When the “poison” is pumped into the prey’s body, the victim will collapse within 15 seconds.
Scientists have yet to explain exactly how the killer beetles can attach the shell of their prey to their back, because the structure of the beetle’s leg joints prevents their legs from reaching. back. What we do know is that the bodies of the victims were glued to the back of the killer beetle using sticky secretions.
These are ferocious insects that can absorb prey liquid and carry their bodies on their backs. They are insects that pierce prey, suck the victim’s body dry and then carry the body on his back, these bugs are often found carrying a huge amount of withered bodies, this is also effective camouflage, as well as protective armor when needed.
The use of this special “armor” as a camouflage makes it easy for some killer bugs to reach unsuspecting victims. Because this “armor” makes them look and smell more like prey. At the same time this “armor” also helps the killer bug against predators, such as geckos or jumping spiders.
Biologist Christiane Weirauch said: “What happens when a gecko tries to catch one of the many insect corpses on its back, it could be the gecko’s last meal because they will. choking on corpses instead of the flesh of a killer bug.
Killer beetles will pierce the enemy’s outer skeleton, such as ants, termites, bees, then they pump a poison to paralyze the victim within a fraction of a second and begin the process of liquefaction from the inside first. when draining the fluid, then place the dead termite body on the body to lure other termites
In an experiment designed to test the killer beetle’s ability to camouflage the jumping spider, the species is known for its excellent vision. Scientists have placed an assassin beetle full of “armor” and a “nude” killer bug inside a cage with bugs. As a result, the dancing spider attacks “naked” killer bugs 10 times higher than an “armor” killer bug.
This creepy disguise of the killer bug is just one of the many natural camouflage patterns that we can know. Outside the natural world, there are still many unique camouflage ways of other creatures such as butterflies with wings with patterns identical to the faces of enemies or worms that look like snakes, …
Camouflage is an organism’s behavior (behavior) that avoids the ability of another subject to observe by hiding in its surroundings. This behavior can help the creature evade the enemy or make it easier to hunt. In nature, animals are under pressure to change to mingle with their habitat or to hide shape; hunted animals thereby evade predators and predators can attack without being detected. Natural disguise is one of them. There are several ways to do this. One is that animals blend into their surroundings; the other way is that the animal transforms into something attractive or has a dangerous appearance. For example, the lizard Anolis caroliensis with the ability to change skin color exactly like the surrounding environment is an illustration of the ingenuity of camouflage behavior in nature. There has always been a constant evolution in the ability to detect disguise, as the ability to hide is also changing. In each pair of hunt-and-hide animals, the level of evolution in disguise and detection differs. Some hidden animals fake movement in nature, for example a leaf in the wind. This is called environmental stealth. Other animals attach or apply natural materials to their bodies for hiding.
