Which species is known as the lesser house fly?

The lesser house fly is scientifically referred to as Fannia spp. This genus includes various species that are similar in appearance to the common house fly but are generally smaller and have distinctive features that differentiate them. For instance, lesser house flies tend to have less prominent bristles and a more slender body compared to their more well-known counterparts.

In addition to size, the ecology of these flies also differs as they prefer to breed in decaying organic matter rather than in trash or human habitats, which are typical for the common house fly, Musca domestica. Understanding the characteristics and behavior of Fannia spp. is important for pest management, particularly in urban and rural settings, as knowing the specific type of fly can influence the choice of control measures.

The other species listed, such as Musca domestica, which is the common house fly, and Calliphora vomitoria, commonly known as the blow fly, represent different taxonomic classifications and behaviors. Each has its unique ecological niche and management strategies, making it essential to correctly identify species for effective pest control.
