We found out that the caterpillar of the moth Galleria mellonella can degrade Polyethylene within 1 hour from the contact.
The larva (or caterpillar) of the moth Galleria mellonella
After contact with the wax worm, the plastic bag is full of holes
The worm habitat is the honeycomb, where it feeds on wax, hence the common name wax worm. Wax is a natural polymer.
It is made of a mixture of complex molecules but they all share the basic structure with the Ch2-Ch2 bond
In this new light, it is comprehensible how these worms evolved a mechanism to break this chemical bond. What are the molecular details of the reaction? We do not know and this is exactly what we want to find out.
