Galleria
greater wax moth, honeycomb moth
Galleria is a monotypic genus of snout moths (Pyralidae) containing only Galleria mellonella, commonly known as the greater wax moth or honeycomb moth. The species is globally distributed and notorious as a pest of honey bee colonies, where larvae tunnel through combs consuming wax, pollen, and honey. Adults are nocturnal; females enter hives after dark to lay eggs in cracks and crevices. The larvae have gained scientific prominence as an alternative model organism for studying host-pathogen interactions, immunology, and antimicrobial therapies, and have shown remarkable ability to degrade polyethylene and polystyrene plastics.
Galleria mellonella
Greater Wax Moth, Honeycomb Moth
Galleria mellonella is a globally distributed moth in the family Pyralidae, best known as a destructive pest of honeybee colonies. The larvae tunnel through honeycomb, consuming wax, pollen, honey, and cast skins of bee larvae, causing significant economic damage to apiculture. Adults are nocturnal, with males producing ultrasonic mating calls at 75 kHz. The species has become an important model organism in biomedical research due to its innate immune system functionally similar to mammals, and has attracted recent attention for the ability of its larvae to degrade polyethylene plastic through salivary enzymes.
Plodia
Indian meal moth (P. interpunctella), pantry moth, flour moth, grain moth, weevil moth
Plodia is a genus of snout moths in the family Pyralidae, subfamily Phycitinae, erected by Achille Guenée in 1845. The genus contains three species, with P. interpunctella (Indian meal moth) being the most economically significant as a cosmopolitan pest of stored food products. Adults are small moths with distinctive wing banding, while larvae infest grains, dried fruits, nuts, and other stored goods. The genus is notable for its association with human food storage environments worldwide.
Zophobas
blind click-beetles
Zophobas is a genus of darkling beetles (Tenebrionidae) native to the Americas. The genus contains several species, with Zophobas morio (also known as Z. atratus) being the most widely recognized due to its commercial importance. Larvae of this species, commonly called "superworms," are larger and more nutritious than yellow mealworms (Tenebrio molitor) and are extensively used as feeder insects for reptiles, birds, and other pets. Research has demonstrated that Z. morio larvae can degrade polystyrene and other plastics through gut microbiome activity, with potential applications in waste management and as a protein source for animal feed and human consumption.
Zophobas atratus
superworm, kingworm, barley worm, morio worm, giant mealworm beetle
Zophobas atratus is a darkling beetle (Tenebrionidae) whose larvae, known as superworms, are widely used as feed for captive reptiles, amphibians, birds, and fish. The species is notable for its larger size compared to the yellow mealworm (Tenebrio molitor), with larvae reaching 50–60 mm in length. Adults measure up to 57 mm. The species has gained attention for its ability to biodegrade polystyrene plastics through mechanical shredding and bacterial gut enzyme activity. It is native to tropical regions of Central and South America but has been introduced globally through the pet trade. The name Zophobas morio is a junior synonym.
