Galleria mellonella, commonly known as the greater wax moth, is a species of moth belonging to the family Pyralidae. It is primarily found in regions where beekeeping is practiced, as its larvae feed on beeswax, honey, and other materials found in beehives. The adult moths are typically grayish-brown and have a wingspan of about 30 to 40 millimeters. The larvae of Galleria mellonella are often used in scientific research, particularly in studies related to entomology and immunology. They are known for their ability to degrade polyethylene, making them a subject of interest for environmental studies focused on plastic waste.
