Dried mealworms are a highly nutritious, protein-rich food source for many insectivorous invertebrates, providing essential nutrients and encouraging natural foraging behaviors. They are widely available from various online retailers in a range of sizes and quantities. 
 
Benefits for Invertebrates
High-Quality Protein & Fats: Dried mealworms are an excellent source of protein (around 50-55%) and healthy fats, which are vital for growth, energy, and muscle development.
Essential Nutrients: They contain crucial vitamins (like B12) and minerals (iron, zinc) that support immune system health.
Exoskeleton Development: For crustaceans like isopods, the rich fiber content can aid digestion and promote strong, healthy exoskeleton development.
Mental Stimulation: Offering mealworms, often by scattering them, can stimulate natural foraging and hunting behaviors, providing valuable mental enrichment.
Convenient Storage: Unlike live insects, dried mealworms are easy to store, have a long shelf life, and are mess-free to handle.
