Are Crickets Omnivores? (Do they eat animals?)

Crickets are omnivorous insects that feed on a variety of plant and animal material. In the wild, crickets are important for recycling nutrients back into the ecosystem. Crickets mostly consume plants, including flowers, seeds, leaves, fruit, and grasses.

While they mostly eat plant material, they also eat dead or injured insects, as well as larvae, aphids, and other small invertebrates.

Because crickets mostly eat plant material, they are primarily classified as herbivores. However, they are not picky and they do have the ability to eat other animals as well, which does allow them to feed as omnivores and scavengers.

Crickets are opportunistic feeders and their diet changes depending on what is available. In the summer months they will eat more plants, while in the winter they will eat more insects.

As you will see in this post, crickets are one of the most diverse groups of animals when it comes to diet!

Primary Diet of the Cricket

Crickets live in grassy fields and forests. They are nocturnal, meaning they are awake at night and sleep during the day. Crickets eat a variety of foods, including plants, grains, larvae, dead or injured insects, aphids, flowers, seeds, leaves, fruit, and grass.

Crickets are omnivores, meaning they eat both plants and animals. Crickets primarily eat plants and grains, like wheat and oats, but when available they will eat larvae, dead or injured insects, and aphids.

Some of the most common food items eaten by crickets are:

  • Grass
  • Wheat
  • Barley
  • Corn
  • Sorghum
  • Oats
  • Milo
  • Other insects

Feeding Habits and Digestion of the Cricket

Crickets eat plants, grains, larvae, dead or injured insects, and aphids by catching them with their front legs and chewing them up.

Crickets eat flowers and seeds by carrying them with their hind legs and placing them in their mouths. Crickets eat leaves and fruit by scraping them up with their forelegs and eating them.

Are Crickets Carnivores, Herbivores or Omnivores?

Crickets are mainly herbivores but are technically omnivores because they eat plants and other animals.

The animals that crickets eat are mostly other insects, including aphids, caterpillars, flies, grasshoppers, moths, beetles, ants, bees, termites, wasps, dragonflies and even butterflies.

Their taste for meat does depend on the species and their habitat, and some crickets like the jerusalem cricket is a true omnivore with no main preference.

Jerusalem crickets, also known as weta, are a type of cricket that is native to New Zealand.

The Jerusalem cricket will eat almost anything it finds in the soil!

These crickets are unique in that they have no wings, and instead rely on their powerful legs to jump around. They are also known for their large size, with some individuals reaching up to 6 cm in length.

One of the most notable differences between Jerusalem crickets and other types of crickets is their diet.

While most crickets feed on plants or small insects, Jerusalem crickets are actually carnivorous and will prey on larger insects such as worms or slugs. This makes them beneficial to farmers, as they can help control pests.

Jerusalem crickets are also known as potato bugs.

Are Crickets Producers, Consumers or Decomposers?

Crickets are consumers because they eat other animals and plants. Crickets are omnivores, which mean they eat both plants and animals.

Crickets ability to eat dead insects allows them to act as detritivores, a type of decomposer, but their primary role is as primary consumers.

Jerusalem crickets will also eat dead organic matter in the soil, and can therefore also function as detritivores or decomposers!

What Type of Consumer is a Cricket?

Crickets are omnivores because they eat both plants and animals. Generally, herbivores are primary consumers, omnivores secondary consumers and carnivores are tertiary consumers.

Can Crickets be Considered Decomposers?

Yes, but it is not their primary mode of feeding. Whereas they do eat dead animals, and can therefore be regarded as scavengers or detritivores, they are not true decomposers as bacteria and fungi. These microorganisms live primarily of dead and decomposing matter.

Where are Crickets in the Food Chain?

Crickets are secondary consumers because they eat other organisms. Animals that only eat plants are primary consumers and are placed on the second trophic level in the energy pyramid.

Are Crickets Autotrophs or Heterotrophs?

Crickets are heterotrophs because they eat other living organisms. Practically no animals are autotrophic because animals do not get their energy directly from the sun like plants do. That is, animals like crickets cannot make their own energy!

What Animals Prey on Crickets?

Predators of crickets include birds, lizards, frogs, toads, spiders, wasps, dragonflies, centipedes, beetles, ants, mice and other small mammals.


In this post I have looked into the diet of crickets and how they are omnivores.

Crickets are a very common insects around the world. They can be found in gardens, parks and grassland, where they feed on grass, flowers and other smaller insects.

Crickets are also important in the agricultural and pet industry, because they cause a lot of crop damage and are used as food for birds and reptiles.

They are also a pest to other insects, so they are not all bad to have in your garden!

Crickets are omnivores, meaning they eat both plants and animals. They are also a very important part of the insect community.

Insects and other invertebrates are an important part of the food chain, and crickets are an important part of the food chain as well. Crickets, like many insects, are preyed on by birds. Birds such as owls, hawks, and owls hunt crickets and would not survive without them in some habitats.
