What color are bottle and blow flies typically described as?

Bottle and blow flies are typically described as blue, black, or green metallic. This distinctive coloration is a key identifying feature of these flies. The iridescent sheen of their bodies reflects light in such a way that gives them a metallic appearance, which can vary based on the species. This characteristic helps differentiate them from other types of flies, which may have more muted or different color palettes. These particular colors are significant for identification, as recognizing the physical appearance of pest species is crucial for effective pest control strategies in structural pest management. Understanding these characteristics assists pest control operators in identifying and addressing infestations.
