Rhaphidophoridae

Some bugs are called cave crickets.

They live in dark spots like caves. They also like damp logs and stones.

These bugs have very long legs. They have long feelers too. The feelers help them touch things. This is good because they cannot see well.

They are active only at night. They do not have wings to fly. They jump to stay safe from danger.

They eat plants and tiny bits of food. These bugs are not scary to people. They are quite harmless.

Some live in sand dunes. They hide in the sand during the day. This helps them keep their water inside.

Many insects are known as cave crickets.

They are also called camel crickets or spider crickets. There are more than 500 species in this group. Most of them live in dark, damp places. You can find them in caves or old mines. They also live under stones or in rotten logs. Some even live in the basements of homes.

These insects are nocturnal. This means they are active at night. They do not have wings, so they cannot fly. Instead, they use long legs to jump away from danger. They have very long antennae, which are feelers used for touch. Since they live in the dark, they rely on touch to find their way.

Most cave crickets are scavengers. They eat bits of plants, animals, and fungi. They are harmless to people. Some species are called sand treaders. They live in sand dunes. They hide under the sand during the day. This helps them stay moist. In the desert, birds like the LeConte's thrasher eat them. In New Zealand, some are called cave wētā.

Many insects are known as cave crickets.

They also go by names like camel crickets or spider crickets. Some people even call them "criders" or "sprickets." There are more than 500 different species in this family. These insects live all over the world. Most of them like to live in dark and damp places. You might find them in caves or old mines. They also live in animal burrows or under stones.

These insects have a very interesting way of moving and feeling. They are flightless, which means they do not have wings. Instead, they use very large back legs to jump. Their legs have a drumstick shape to help them. They also have very long and thin antennae. Because they live in the dark, they use these antennae to touch things. This helps them find their way when they cannot see well. They are nocturnal, so they are mostly active at night.

Humans have been noticing these insects for a very long time. There is an old engraving on a bison bone. This was found in the Cave of the Trois-Frères. It shows a female insect from the genus Troglophilus. This tells us that prehistoric people likely saw them long ago. Some people think they might have been pets or pests back then. They are often seen as accidental invaders in modern homes. They might wander into basements, drains, or even laundry areas.

There are many specific types of these crickets in different places. In New Zealand, people call them jumping or cave wētā. Some live in very cold areas near ice. One is called the Mount Cook "flea" in New Zealand.

In Japan, they are sometimes called kamado-uma. People there also call them benjo korogi. These names show how much different cultures notice them.

Cave crickets play a role in many different environments. Most of them are scavengers. This means they eat bits of plants, animals, and fungi. They are completely harmless to people. Some special types are called sand treaders. They live in sand dunes in places like California and Utah. They hide under the sand during the day to stay moist. In the desert, they serve as food for scorpions. A bird called the LeConte's thrasher also hunts them in the sand.

The Rhaphidophoridae are a worldwide family of insects within the suborder Ensifera. They are known by many common names, including cave crickets, camel crickets, and spider crickets. Some people even call them "criders" or "sprickets." In New Zealand, certain members are called jumping or cave wētā.

While they may look like field crickets or members of the Tettigoniidae family, they are actually quite distinct. There are more than 500 described species in this group. They play unique roles in various ecosystems around the globe.

Most Rhaphidophoridae possess very specific physical adaptations for life in the dark. They are all flightless, meaning they lack wings entirely. Their bodies are often brownish and have a humpbacked appearance. They are characterized by extremely long, slender antennae that arise close together on the head.

They also have very large hind legs. These legs consist of drumstick-shaped femora and long, thin tibiae. These limbs allow them to jump effectively to avoid predators, which is vital since their vision is often limited.

These insects are primarily nocturnal, meaning they are most active during the night. Many species inhabit cool, damp environments such as caves or old mines. You might also find them in animal burrows, under stones, or within rotten logs and hollow trees. Some species even live in alpine areas near permanent ice, such as the Mount Cook "flea" in New Zealand. Others, known as sand treaders, live in sand dunes. These sand treaders burrow into the sand during the day to minimize water loss.

Rhaphidophoridae are categorized into several subfamilies and tribes. The Ceuthophilinae subfamily includes many North American cave crickets and camel crickets. The Dolichopodinae subfamily is found in southern Europe and western Asia. The Macropathinae subfamily includes Gondwanan cave crickets found in Australia, New Zealand, South America, and South Africa.

New Zealand is particularly diverse, containing many genera like Pachyrhamma and Macropathus. There is even an unnamed genus discovered in 2005 within a cave in the Grand Canyon–Parashant National Monument. This specific insect has unique, functional grasping cerci on its posterior.

Humans have interacted with these insects for thousands of years. An engraving of a female Troglophilus was found on a bison bone in the Cave of the Trois-Frères. This suggests that prehistoric populations in the Magdalenian period may have seen them as pets or pests. In modern times, they are often considered "accidental invaders" in human buildings. They frequently wander into basements, drains, sewers, and laundry areas. In Japan, they are common in chilly regions and are colloquially called benjo korogi, which means "toilet cricket."

Ecologically, most Rhaphidophoridae act as scavengers. They survive by eating various plant, animal, and fungi materials. This scavenging helps recycle nutrients within their environments. In the sand dunes of California and Utah, they serve as a vital food source for scorpions. They are also preyed upon by a specialized bird called the LeConte's thrasher. This bird searches the Mojave and Colorado Deserts for the debris left by hiding sand treaders.

Understanding Rhaphidophoridae helps scientists learn about specialized survival. Their long antennae are essential for navigating lightless environments through touch. Because they often live in habitats where nutrients are scarce, their scavenging lifestyle is a key survival strategy. Whether they are living in deep caves or suburban basements, these insects demonstrate how life adapts to specific, often difficult, niches.
