What Do Crickets and Grasshoppers Eat?

Crickets and grasshoppers, often confused due to their hopping locomotion and shared classification within the order Orthoptera, are common insects found across diverse environments. Despite their superficial similarities, these creatures exhibit distinct characteristics, particularly concerning their dietary habits. Understanding their diet reveals much about their ecological roles and biological adaptations.

The Diet of Crickets

Crickets are widely recognized as omnivores, meaning their diet in the wild encompasses both plant and animal matter. They are opportunistic feeders, consuming a broad spectrum of available food sources, which allows them to thrive in various ecosystems as important scavengers. Their plant-based consumption includes decaying plant material, fungi, seeds, young plants, and various parts of flowers, fruits, and grasses, as well as organic debris like rotten wood and algae, especially in damp environments where these sources are plentiful. Beyond vegetation, crickets actively forage for protein, feeding on small insects like aphids and insect larvae. When other food sources are scarce, crickets also consume carrion or dead insects, a scavenging tendency that contributes to decomposition and nutrient recycling within their habitats.

The Diet of Grasshoppers

Grasshoppers are primarily herbivores, relying almost exclusively on plant material for their sustenance. Their diet typically consists of a wide range of vegetation, which varies based on their specific habitat and what plants are readily available, with grasses, leaves, and stems forming a significant portion. They feed on various crops, including rye, barley, cotton, corn, alfalfa, and wheat, often causing agricultural damage. Grasshoppers possess specialized mouthparts, including mandibles, adapted for cutting and grinding tough plant fibers. While predominantly plant-eaters, some species may consume less nutritious items like moss, fungi, or bark if preferred plant foods are scarce, and in rare instances and under extreme conditions, they might consume carrion or animal feces to obtain additional protein.

Feeding Crickets and Grasshoppers in Captivity

Providing a suitable diet for captive crickets and grasshoppers is important, whether as pets or feeder insects. For crickets, a diverse diet mirroring their omnivorous nature is recommended. This can include fresh vegetables such as leafy greens, carrots, potatoes, and squash, along with fruits like apples, oranges, and bananas. Grains, such as wheat germ, rice cereal, or alfalfa, also contribute to their nutritional intake. Commercial cricket foods are available, often formulated with ingredients like dehulled soybean meal, ground corn, fish meal, and various vitamins and minerals to ensure a balanced diet.

For grasshoppers, a diet of fresh plant material is suitable. They readily consume romaine lettuce, oats, corn, and various grasses. Supplementing with other vegetables like carrots, sweet potatoes, and apples can provide additional nutrients.

Both crickets and grasshoppers require a consistent water source. Crickets can easily drown in open water, so providing moisture through water gels, moist cotton balls, or fresh, damp produce is advised. Grasshoppers primarily obtain water from the plants they eat, but their food can be lightly misted with water in dry environments to ensure hydration.
