What allows *Galleria mellonella* larvae to consume beeswax?
Answer
Enzymes that break down complex esters and long-chain fatty acids
The capability of the wax moth larva to consume beeswax is a defining characteristic of its specialized diet, separating it from most other insects. This process is enabled by the presence of specific enzymes synthesized within the larva. These enzymes are highly effective at breaking down the molecular structure of beeswax, specifically targeting the complex esters and the long-chain fatty acids that make up this durable substance. This digestive capability is what allows the larva to not only utilize the stored food (honey and pollen) but also to metabolize the structural material of the comb itself, leading to extensive tunneling.
