Do Crickets Eat Mushrooms and Fungi?

Crickets are common insects found across diverse environments, often serving as both agricultural pests and a commercially raised food source. Crickets are opportunistic feeders, and their diet includes fungi and mushrooms, integrating these resources into their broad nutritional profile.

Understanding the Cricket Diet

Crickets are classified as omnivores, meaning their natural diet is varied and depends heavily on the availability of resources in their immediate environment. Their opportunistic feeding habits enable them to thrive in many different habitats worldwide. The bulk of a cricket’s natural intake consists of plant-based materials, such as leaves, stems, seeds, and grasses.

Crickets are also important detritivores, frequently consuming decaying organic matter, which helps recycle nutrients back into the ecosystem. Beyond plant material, crickets actively seek out sources of protein, often consuming smaller insects, larvae, or carrion. This scavenging behavior is driven by the need for varied nutrients to support rapid growth and reproduction.

In captivity, this broad dietary requirement is often met with commercial feeds, supplemented with fresh vegetables and fruits. The consistent need for hydration also influences their food choices, making moisture-rich items a frequent target.

Fungi and Mushrooms as a Food Source

The consumption of fungi and mushrooms by crickets is primarily a function of their opportunistic scavenging and the unique properties of these food items. Fungi provide a highly attractive combination of moisture and texture that meets immediate biological needs. Mushrooms, especially the fruiting bodies, are typically soft and easy for the crickets’ mandibles to process, unlike tougher plant fibers.

A major driver for this consumption is the need for water, as mushrooms can contain a very high percentage of moisture. In dry environments, a fungus can serve as a crucial source of hydration, allowing crickets to maintain their internal water balance. Crickets are frequently found feeding on soft or decaying mushrooms and molds because these environments satisfy both their dietary and hydration requirements simultaneously.

Fungi also offer valuable nutritional components that supplement the crickets’ largely plant-based diet. They provide carbohydrates, protein, and minerals, which are beneficial for the insect’s development and health. Some mushrooms contain crude protein levels that can reach 20–30% of their dry matter, offering a rich amino acid profile.

Crickets are often drawn to the mycelium and fruiting bodies of fungi growing on decomposing organic matter, like fallen leaves or wood. This overlap in habitat means that fungi are a readily available food source within the detritus where crickets typically forage. This relationship highlights the cricket’s role in breaking down fungal matter as part of the larger nutrient cycling process.
