Crickets are common insects found globally in diverse environments. These adaptable creatures are omnivores, meaning their diet consists of both plant and animal matter, allowing them to thrive in various ecosystems. Understanding their dietary habits is helpful for those encountering them in nature or caring for them in captivity.
What Crickets Eat in Nature
In nature, crickets consume a broad variety of organic materials. They forage on plant matter, including fresh leaves, stems, roots, seeds, and fruits. They also scavenge on decaying organic material, fungi, and insect remains. This flexible diet allows them to adapt to available resources, contributing to nutrient recycling. Some cricket species, like field crickets, specifically target grass and tender shoots, while others might consume insect larvae or aphids.
Feeding Crickets as Pets
For captive crickets, whether pets or feeder insects, a balanced diet is important for their well-being. Commercial cricket chows often contain a blend of grains, protein, and vitamins. Supplementing these with fresh items provides a broader spectrum of nutrients.
Suitable vegetables include leafy greens such as collard greens, mustard greens, kale, romaine lettuce, and spinach (in moderation), along with carrots, squash, sweet potatoes, and zucchini. Before offering any produce, wash it thoroughly to remove potential residues.
Fruits can also be provided sparingly due to their sugar content; apples, oranges, and bananas are acceptable choices. Grains like rolled oats, cornmeal, wheat germ, and unsweetened cereals offer carbohydrates and fiber. For feeder crickets, “gut loading” involves feeding them nutrient-rich foods to enhance their nutritional value for the consuming animal. This process ensures that beneficial vitamins and minerals are transferred, supporting the health of the predator. A varied diet benefits cricket health and, consequently, the animals that prey on them.
Hydration for Crickets
Crickets require constant access to water. While some moisture can be obtained from fresh fruits and vegetables, this is usually insufficient as a sole water source. In captivity, provide water in a way that prevents drowning, as crickets can easily drown in open dishes.
Safe methods include shallow dishes with water crystals or gels, allowing crickets to absorb moisture without risk. Another technique involves placing a damp sponge, paper towel, or cotton ball in a shallow container, ensuring it remains moist without standing water. Misting the enclosure lightly can also contribute to hydration, particularly for younger crickets or in drier conditions.
Foods to Never Offer
Certain foods are harmful to crickets and should be avoided. Do not offer produce treated with pesticides or not thoroughly washed, as it can be toxic.
Moldy or spoiled food poses health risks, introducing harmful bacteria and fungi. Some plants are toxic to crickets, such as citrus peels in large quantities and certain strong herbs. Processed human foods, including candy, greasy items, or salty snacks, lack necessary nutrients and can cause digestive issues. An improper diet can lead to health problems for crickets and potentially affect any animals that consume them.
