1. Understanding Blow Flies
Blow flies, belonging to the Calliphoridae family, are among the first insects to arrive at a carcass, making them crucial in forensic entomology. According to research from Texas A&M University, their rapid arrival and development stages provide valuable information for estimating the time of death in criminal investigations. Identifying blow flies is essential for effective pest control.
1.1. What are Blow Flies?
Blow flies are insects known for their metallic sheen and are attracted to decaying organic matter. These flies, also known as carrion flies, play a significant role in decomposition.
1.2. Appearance and Characteristics
Blow flies are typically characterized by their metallic blue, green, or bronze bodies. Adult blow flies range from 1/4 to 1/2 inch in length. The metallic sheen of their bodies distinguishes them from other flies.
- Color: Metallic blue, green, or bronze.

1.3. Blow Fly Life Cycle
The life cycle of a blow fly includes egg, larva (maggot), pupa, and adult stages. Understanding this life cycle is crucial for effective control.
- Egg Stage: Female blow flies lay their eggs on decaying organic matter.
- Larva Stage (Maggot): Eggs hatch into larvae, commonly known as maggots, which feed on the decaying matter. Maggots are cream-colored, legless, and eyeless, ranging from 3/8 to 7/8 inch long.
- Pupa Stage: After feeding, maggots transform into pupae, which have a hardened outer shell. The pupa stage occurs in a dry, secluded location.
- Adult Stage: Adult blow flies emerge from the pupal casing, ready to reproduce and continue the cycle.
1.4. Blow Fly Behavior and Habits
Blow flies are attracted to the odor of decaying organic material, making garbage cans, dead animals, and rotting food prime breeding sites. Their keen sense of smell allows them to locate these sources quickly. Blow flies prefer laying eggs on meat or dead animals. Some species, like the screwworm fly, lay eggs on living animals.
