What Do Cave Crickets Eat?

Written by: Gemmali Dizor

Cave crickets, also known as cave wetas or camel crickets, are a group of insects commonly found in caves and other underground habitats. These crickets are known for their long, slender legs and ability to climb walls and ceilings. They are also known for their distinctive chirping sound, produced by males during mating.

What Do Cave Crickets Eat?

In the wild, cave crickets are opportunistic feeders and will eat a variety of different foods. They are known to consume various types of organic matter, such as dead insects, fungi, and plant material. They have also been eating other arthropods, such as spiders and millipedes. Some cave crickets are also known to feed on the feces of bats and other cave-dwelling animals. 

This feeding behavior adapts to the challenging conditions of the underground environment where resources are scarce, and competition for food is high. Moreover, some cave crickets have evolved specialized mouthparts that allow them to chew through rigid plant material and wood, which is not a common food source for other crickets species. Additionally, cave crickets have been observed to scavenge on bat guano, which is rich in nutrients and helps them to survive in their underground habitat.

Cave Cricket Feeding Habits in Captivity

Cave crickets can be kept in captivity as pets or for research purposes, but it’s essential to understand their feeding habits to ensure they are well cared for. In captivity, cave crickets can be fed a diet of fresh fruits and vegetables and various types of commercial cricket food. It’s important to note that they can’t survive on only one kind of food and need a variety of food sources to maintain a healthy diet. 

Fruits and vegetables can be a source of hydration, moisture, vitamins, and minerals. Commercial cricket food, on the other hand, is a convenient and complete food source that provides the crickets with all the necessary nutrients. Additionally, a source of calcium, such as cuttlebone or eggshells, should be provided to help them develop strong exoskeletons. It is also essential to give a clean and fresh water source to prevent the growth of harmful bacteria.

The Importance of Hydration for Cave Crickets

Providing a source of hydration is crucial for the survival of cave crickets in captivity. Like many other arthropods, these insects have an exoskeleton, which helps protect them from predators and desiccation. An exoskeleton is not flexible and does not allow for water exchange, so cave crickets need to obtain moisture from the environment to survive. 

In the wild, cave crickets may obtain moisture from the damp cave walls or the bodies of the insects they eat. In captivity, a small dish of water should be provided for them to drink from. It’s essential to keep the water dish clean and fresh to prevent the growth of harmful bacteria.

Additionally, providing fruits and vegetables is crucial as part of their diet. This can help to provide them with additional hydration sources and also provide them with extra vitamins and minerals, which are essential for their growth and survival.

Not providing a source of hydration can lead to dehydration and death, so it’s crucial to monitor the water dish and refill it as needed. A hydrated cricket will have a plump and shiny exoskeleton. In contrast, a dehydrated cricket will have a soft and wrinkled exoskeleton, which is a sign that they are not getting enough moisture.


In conclusion, cave crickets are unique and exciting insects that are well-adapted to life in underground habitats. They have a diverse and opportunistic diet, which allows them to survive in the challenging conditions of their subterranean habitat. In captivity, it is essential to understand their dietary needs and provide a varied diet that includes fresh fruits and vegetables, commercial cricket food, and a source of calcium. 

Additionally, a source of hydration is essential for their survival, and a clean and fresh water source should be provided at all times. By understanding and meeting the dietary needs of cave crickets, they can be kept as healthy and fascinating pets or research subjects. Overall, cave crickets are an exciting addition to any insect collection and are relatively easy to care for as long as their dietary needs are met.
