They have four wings. These wings have many lines on them. They use their mouths to chew food.
Young bugs are hunters. Some hide in the sand to catch food.

It is fun to look for them!
Neuroptera are insects with net-like wings.
There are about 6,000 types of these insects. This group includes lacewings and antlions. Most adults have four wings. These wings are the same size. They have many veins that look like a net. Most adults use their mouths to chew.
Young insects, called larvae, are hunters. They eat other small bugs. Some larvae hide in the sand. These are antlions. They dig pits to catch prey. Other larvae live in water. Some eat sponges. Some larvae make silk. They use this silk to make a cocoon. A cocoon is a hard shell for resting.
These insects are very old. They first appeared in the Permian period. Long ago, some had very large wings. We call them the butterflies of the Jurassic.
Some people even eat these insects. In New Guinea, people eat them for food. This may help them stay strong.
Neuroptera are a large group of insects with net-like wings.
The name comes from Greek words meaning "nerve" and "wing." This group includes many different types like lacewings and antlions. There are about 6,000 different species in this order. These insects are important because they help control pests. Some types eat aphids, which are small bugs that can hurt plants. Scientists have even looked into using them for biological control. This means using helpful bugs to manage other insect populations.
These insects go through a full life cycle called complete metamorphosis.
First, they start as larvae, which are the young insect stage. Most larvae are predators that hunt other small creatures. Some larvae, like antlions, hide in pits in the sand. They wait for prey to fall into their traps. Other larvae live in water and eat freshwater sponges.
To rest, they spin silk to make a cocoon. Some larvae use special parts of their bodies to make this silk. Eventually, the adult insect uses its jaws to cut out of the cocoon.
Neuropterans have been around for a very long time.
They first appeared during the Permian period. Fossils from Siberia and Australia show us they lived back then. During the Mesozoic era, they continued to grow and change. Some ancient groups, called Kalligrammatidae, had huge, colorful wings. People often call them "the butterflies of the Jurassic."
These large insects lived from the Jurassic to the Cretaceous period.
Adult insects in this group have many interesting features.
They usually have four wings that are about the same size. These wings have a pattern of veins that look like a net. Most adults have mouthparts that are built for chewing. They also have large eyes on the sides of their heads.
The larvae have long jaws used for piercing and sucking. Their bodies are soft, and they have three pairs of legs. Many larvae even cover themselves in debris to hide from enemies.
Humans have found many ways to interact with these insects.
Five different species of Neuroptera are eaten by people. Around the world, there are over 1,600 insect species that humans eat. In the New Guinea Highlands, people eat these insects as part of their diet. They claim that eating them helps them stay strong and have great stamina. Even though they are small, these net-winged insects play a big role in nature and human life.
Neuroptera is a large order of insects known as net-winged insects.
The name comes from the Ancient Greek words *neûron*, meaning nerve, and *pterón*, meaning wing. This group contains about 6,000 different species. It includes familiar insects like lacewings, antlions, and mantidflies. Neuroptera is part of a larger group called Neuropterida. This group also includes Megaloptera, which are fishflies and dobsonflies, and Raphidioptera, known as snakeflies. These insects are important because they play various roles in different ecosystems.
Adult neuropterans have a specific body structure. They possess four membranous wings that are usually similar in size and shape. These wings feature a complex pattern of veins that look like a net. Most adults have large lateral compound eyes on the sides of their heads. They also have chewing mouthparts, which are mandibles used for eating. Some species have special sense organs in their wings. Others have bristles that help link their wings together during flight.
The life cycle of these insects involves complete metamorphosis. This means they change through distinct stages: egg, larva, pupa, and adult.
The larval stage is often very different from the adult. Most larvae are specialized predators. They have elongated mandibles designed for piercing and sucking their prey. Their bodies usually have three pairs of thoracic legs. Each leg ends in two claws. Some larvae even use adhesive discs on their abdomen to help them move.
Larvae use different strategies to survive and hunt. Many species, such as certain green lacewings, eat aphids and other pests. Some larvae cover themselves in debris, like dead insects, to use as camouflage.
Antlions take this to an extreme by burying themselves in sand pits. They wait in these pits to ambush prey. Other larvae have very different lives. Some live in water and eat freshwater sponges. Others are root feeders. To prepare for the next stage, larvae spin silk cocoons. They use Malpighian tubules to produce this silk. In some families, a special part called a spinneret helps build the cocoon.
The history of Neuroptera stretches back millions of years. They first appeared during the Permian period. Fossils found in the Tunguska basin in Siberia and in Australia prove this.
During the Mesozoic era, they continued to diversify. The extinct family Kalligrammatidae is a famous example. These insects lived from the Jurassic to the Cretaceous period. They had large, patterned wings and are often called "the butterflies of the Jurassic."
After the Cretaceous period ended, the diversity of these insects seemed to decline.
Scientists study the relationships between these different insect groups using molecular analysis. In 2018, researchers used mitochondrial rRNA and mitogenomic data to study their evolution. These studies help place families like Megaloptera and Raphidioptera in a family tree.
The fossil record is also vital for understanding this history. For example, fossils found in Baltic amber show ancient osmylids. Other fossils in Burmese amber help scientists date when certain groups began to spread. This work helps us understand how the entire order of Neuroptera evolved over time.
Humans interact with Neuroptera in several surprising ways. Some species are used for biological control. This means using helpful insects to manage pest populations in crops.
Interestingly, humans also eat some of these insects. Five species of Neuroptera are among the 1,681 insect species eaten by humans globally. In the New Guinea Highlands, people eat insects including Neuroptera. They claim that eating them helps maintain muscular build and great stamina. Even though they are small, these net-winged insects are connected to many parts of our world.
