Galleria mellonella, commonly known as the greater wax moth, is a small moth species found globally. It thrives in warm, dark environments and is known for its larvae, which feed on beeswax and can infest honeybee colonies. The larvae are notable for their ability to degrade polyethylene plastic.

Galleria mellonella, commonly known as the greater wax moth, is native to Europe. However, it is now found in many parts of the world, including Asia, Africa, and the Americas, due to its association with beekeeping activities.

The greater wax moth thrives in environments where honeybee hives are present. These moths favor warm climates, as they are sensitive to cold temperatures. They are commonly found in temperate regions during warmer months and in tropical and subtropical areas throughout the year.

Galleria mellonella primarily inhabits areas where honeybee hives are located. The larvae feed on the beeswax, honey, and other hive debris, often causing damage to the hive. They play a role in the ecosystem by breaking down and recycling wax and other organic materials. While they can adapt to various environmental conditions, they are most successful in environments where beekeeping is practiced.
