G. mellonella, commonly known as the 'great wax moth' may be one of the answers to the problem of plastic pollution.  Their larvae enjoy chowing down on polyethylene, the most common type of plastic.  100 worms are able to ingest 92 milligrams of plastic bag material in a 12-hour period.  I'm not sure which problem would be worse, all the plastic bags or the larvae needed to do the job.
