Fly

Natural Habitat

Flies are found in nearly every terrestrial habitat on Earth, from urban environments to forests, deserts, and polar regions. Their presence is often associated with available food sources and breeding sites, which can include decaying matter, water bodies, or other organisms.

Diet & Feeding

The diet of flies varies widely by species. Many generalist flies, like house flies, feed on decaying organic matter, garbage, feces, and sugary substances. Other flies are parasitic, predacious, or feed on nectar and pollen.

Behavior Patterns

Flies are typically active during the day, performing various behaviors such as seeking food, mates, and suitable places to lay eggs. Some species, like house flies, are attracted to light, while others might be more active in dim conditions. Their erratic flight patterns are often a defense mechanism.

Risks & Benefits

Risks include being vectors for diseases (e.g., house flies carrying bacteria) and agricultural pests. Benefits include being important pollinators (e.g., hoverflies), decomposers, and a food source for other animals. Some flies are also used in forensic entomology.
