How fat can silk worms get?

Silkworms, particularly the larvae of the Bombyx mori species, can grow significantly in size during their larval stage, reaching up to 3 inches in length and weighing about 1-2 grams. Their fat accumulation is mainly due to the energy reserves needed for metamorphosis into moths. However, excessive fat accumulation is not typical as it can lead to developmental issues. Overall, their growth is closely tied to their diet and environmental conditions.
