Crickets are omnivores with a diverse diet that includes both plant and animal matter. In the wild, they primarily eat a variety of plant materials such as leaves, grass, fruits, vegetables, flowers, seeds, and shoots. They also consume decaying organic matter like dead insects and fallen fruits, which helps with nutrient recycling in ecosystems. Additionally, crickets may eat fungi, algae, insect larvae, aphids, eggs, and sometimes other small insects, showing opportunistic predatory and scavenging behavior

. In captivity, crickets are commonly fed a combination of fresh fruits and vegetables-such as spinach, lettuce, cabbage, carrots, sweet potato, apple, banana, broccoli, and cauliflower-as well as dry protein-rich foods like crushed cat or dog biscuits, nuts, seeds, or commercial cricket food. Providing both wet and dry food sources ensures hydration and balanced nutrition, which is important for their health and for the nutritional value they pass on if used as feed for pets like reptiles. Protein content should be moderate (below 30%) to avoid aggression among crickets

. In summary, crickets eat:

• Plant matter: leaves, grass, fruits, vegetables, flowers, seeds, shoots
• Decaying organic material: dead insects, fallen fruit, plant debris
• Small animals: insect larvae, aphids, eggs, other insects occasionally
• Fungi and algae in some environments
• In captivity: fresh produce plus protein-rich dry foods or commercial mixes

This omnivorous and adaptable diet helps crickets thrive in various environments.
