House fly

Found globally in close association with humans, particularly in areas with organic waste, livestock, and food processing.

Adults feed on liquid or semi-liquid substances including food waste, rotting organic material, and secretions. They use sponging mouthparts to liquefy solid food with saliva.

Active during the day, resting at night. They exhibit a four-stage life cycle (egg, larva, pupa, adult) which can be completed in as little as 7 to 10 days in warm conditions.

Risks include the transmission of numerous pathogens such as salmonella and E. coli by carrying bacteria on their bodies and mouthparts. Benefits are limited but include their role as decomposers and a food source for other animals.
