The ProRep Beetle Grub 1 substrate is a specially prepared food source for beetle larvae, made from mature broadleaf tree leaf litter. During preparation, the material is inoculated with white fungus, which is essential for breaking down cellulose and lignin into a form that beetle larvae can digest.
This substrate provides larvae with the nutrition they require for steady growth and healthy development, replicating the natural food sources found in forest habitats.
• Made from mature broadleaf leaf litter
• Inoculated with essential white fungus for digestion
• Provides a naturalistic diet for beetle larvae
• Supports steady growth and development
• Easy to use in breeding setups
The ProRep Beetle Grub 1 is an essential substrate for providing beetle larvae with the correct nutrition for healthy rearing.
Beetle larvae require a balance of nutrition at different life stages, and this is where ProRep Beetle Grub 1 and Beetle Grub 2 complement each other.
• Beetle Grub 1 (leaf litter based) is best for early-stage larvae or species that naturally feed on softer, decayed plant matter.
• Beetle Grub 2 (hardwood chip based) is ideal for later-stage larvae or species that require a more fibrous, wood-rich diet.
In practice, many breeders mix the two in varying proportions depending on the beetle species. For example, some species thrive on a 50/50 blend throughout development, while others may start on Beetle Grub 1 and transition gradually to Beetle Grub 2 as they grow.
Using the correct balance helps replicate natural conditions, ensuring healthy growth, proper development, and higher success rates in beetle breeding projects.
Using Beetle Grub 1 & 2
• Grub 1: Leaf litter-based, ideal for early-stage larvae or species feeding on softer matter.
• Grub 2: Hardwood-based, suited to later-stage larvae or species needing fibrous diets.
• Mix in different ratios depending on species; some start on Grub 1 and move to Grub 2, while others thrive on a 50/50 blend.
Provides balanced nutrition for healthy growth and development in beetle breeding projects.
