High-Protein Krill Pellets - 10g (approx +250 pellets)


This listing is for 10g of protein pellets (45% protein content) which can be added to the substrate as extra protein supplements for beetle larvae, to promote faster larval growth and a larger adult size.

Protein pellets can be fed to larvae of many of the larger species beetles once they reach the final L3 stage. As a guide, I give 5 krill pellets every week per L3 larva of larger species such as Mecynorrhina torquata ugandensis. Therefore, 10g (250 pellets) will be enough to support one larva for 50 weeks, or a group of 10x larvae for just over a month. *Do not add excessive amounts of protein pellets to the substrate as any that they cannot eat in time will mould over and rot. Less is always better in this case.*

These krill protein pellets are my go-to additives for carnivorous species such as Goliath Beetles and other protein craving Cetoniinae species, due to the high protein and low fat content. Not all species may readily eat these pellets, especially the less carnivorous species that prefer vegetable-based protein instead. For those, the veggie tablets I have available are more suitable.

I have trialled-and-errored many different brands and varieties of protein pellets over the years, and I have had very good results with the protein pellets I have for sale here. They are a good source of extra protein for Flower Beetles (Cetoniinae), Rhino Beetles (Dynastinae) and Stag Beetles (Lucanidae). Protein additives are also necessary when raising larvae of certain species like Goliath Beetles (Goliathus spp.) that have to feed on a high-protein diet to gain weight.

The use of dog food as protein additives are promoted by some people, but the disadvantage of using dog food is that they tend to rot very quickly, be quite smelly, and contain a low percentage of protein (~20%), making them less ideal.
