They hunt other bugs for food. They have a long mouth to help them eat. These bugs can be bright colors. They help us by eating pests.

Some bugs are called assassin bugs.
They are hunters that live on land. Most have a narrow neck and a strong body. They use a long, curved mouth to eat.
This mouth helps them hunt other bugs. Some bugs even hide using bits of dust. This helps them stay safe from others. These bugs can be red, black, or orange.
They are very interesting to see!
Assassin bugs are a large group of insects.
There are about 7,000 different species. Most of these bugs live on land. They are hunters that wait for prey to come near.
Most have a narrow neck and a strong body. They also have a long, curved mouth called a proboscis.
These bugs use their mouth to hunt in a special way. They inject saliva into their prey. This saliva has enzymes that melt the insides of the bug. This is called extraoral digestion. The bug then sucks up the liquid.
Some young bugs hide by covering themselves in dust or debris. This helps them stay safe from predators.
Some bugs in this family do not hunt other insects. A group called kissing bugs drinks blood instead. They often bite people near the eyes or lips. These bugs can spread a sickness called Chagas disease. It is important to be careful around large assassin bugs. Their bite can be very painful.
Assassin bugs are a huge group of insects.
They belong to a family called Reduviidae. This family is found all over the world. Most of these bugs live on land and are ambush predators. This means they wait for prey to come near them.
There are about 7,000 different species in this family. They belong to a large group of true bugs. Some subfamilies have special names like ambush bugs or thread-legged bugs.
These bugs have a very special way of eating. They have a long, curved mouth called a proboscis. They use this to inject saliva into their prey. This saliva contains enzymes that melt the insides of the insect. This way of eating is called extraoral digestion.
The bug then sucks out the liquid. This saliva can even kill prey that is much larger than the bug. Some bugs even use their mouth to make sounds. They rub the proboscis against a ridge to scare away enemies.
Scientists have studied these bugs for a long time. The name Reduviidae comes from the genus Reduvius. This name comes from a Latin word meaning "hangnail."
Some bugs are very good at hiding. The masked hunter, or Reduvius personatus, covers itself in dust. In India, the species Acanthaspis pedestris uses debris to hide. Some people even keep these bugs as pets. They help by hunting pests like bedbugs or cockroaches.
Not all assassin bugs hunt other insects. A group called kissing bugs drinks blood instead.
They are part of the Triatominae subfamily. These bugs often bite humans near the eyes or lips. This is how they got their common name. Some of these bugs can spread Chagas disease. This disease is very serious in Central and South America. It causes about 12,000 deaths every year. You should be careful with large bugs because their bite is very painful.
These bugs have been around for a very long time. Fossils show they lived during the Cretaceous period.
One fossil genus is called Simplicivenius. Scientists use DNA to learn about their history. They think these bugs split from other groups during the Jurassic period. Some bugs have legs like a praying mantis to catch prey. Others, like the feather-legged bug, have special hairs on their legs. These different shapes help them survive in their homes.
The Reduviidae family is a massive group of insects known as assassin bugs.
They belong to the suborder Heteroptera within the order Hemiptera, which are true bugs. Most species in this family are terrestrial ambush predators. This means they wait on land for prey to come within reach. There are over 7,000 described species in this family. They are organized into more than 20 recognized subfamilies. This diversity makes them one of the largest families of true bugs in the world.
Most assassin bugs share a very specific body shape. They typically have an elongated head with a distinct, narrow neck. Their most famous feature is a prominent, segmented, tubular mouthpart called a proboscis. Some scientists also call this structure a rostrum. The tip of the proboscis fits into a ridged groove on the prosternum. By rasping the proboscis against these ridges, the bug can produce sound through stridulation.
This sound is often used as a way to discourage potential predators.
Assassin bugs use a unique method to eat called extraoral digestion.
When they catch prey, they use the long rostrum to inject a lethal saliva. This saliva contains powerful enzymes that liquefy the internal tissues of the prey. Once the insides are turned to liquid, the bug sucks them out. This saliva is so effective that it can kill insects much larger than the bug itself. Some species have legs with tiny hairs to help them hold onto struggling prey. Others, like the Phymatinae subfamily, have forelegs that function like a praying mantis to grab food.
Many species have developed incredible ways to hide from enemies or hunt more effectively.
The masked hunter, Reduvius personatus, camouflages itself by covering its body with dust. In Tamil Nadu, India, the species Acanthaspis pedestris uses debris to hide. Some bugs are even specialized for specific diets. The Ectrichodiinae subfamily eats millipedes, while feather-legged bugs hunt ants. The Australian species Ptilocnemus lemur has a fascinating hunting method. Its nymphs wait for an ant to bite the feathery tufts on their hind legs before striking.
While most are predators, some subfamilies have evolved to be blood-suckers.
These are known as haematophagous species, meaning they feed on blood. The Triatominae subfamily includes many of these bugs, which are often called kissing bugs. They earned this name because they tend to bite humans near the eyes or lips while they sleep. This feeding habit likely evolved from ancestors that lived in the nests of mammals. Some species, like Cavernicola pilosa, live among bat roosts.
These blood-feeding bugs can cause serious health problems for humans.
Several species in Central and South America transmit Chagas disease, also called American trypanosomiasis. This is a potentially fatal condition caused by trypanosomes. Chagas disease is responsible for approximately 12,000 deaths every year. Because of this, large specimens should be handled with extreme caution. If they feel threatened, they can deliver a very painful stab with their proboscis. This injection of venom or digestive juices can be medically significant.
Scientists have studied the history and evolution of the Reduviidae for a long time. The name Reduviidae comes from the type genus, Reduvius. This name is derived from the Latin word reduvia, meaning "hangnail" or "remnant."
Fossils of this family date back to the Lower Cretaceous period. One known fossil genus is Simplicivenius, which belongs to the subfamily Reduviinae. Using molecular clock data, researchers suggest the family split from other Cimicomorphs during the Jurassic period. Modern taxonomy uses morphological characteristics, but new DNA research is helping to refine how we group these diverse insects.
