Can Flies Die of Starvation?

Flies can die from starvation, but the cause isn’t always obvious. They may be preyed upon by predators or suffer from a disease, or they may simply not be in the right environment. Luckily, there are some simple ways to ensure that your housefly will survive.

The best way to ensure that your fly doesn’t starve to death is to provide them with enough food. Eggs are an essential part of the diet of many species of flies, and they contain proteins, sugars, and carbohydrates that they need to survive. If a single egg doesn’t supply enough food, it’s possible for them to starve to death.

In order to determine if flies can die from starvation, researchers first observed their behavior. Adult flies gathered around pierced, stained, or untreated conspecific eggs. Their abdomens began to accumulate green dye, indicating that they were starving. When they were provided with ruptured larvae, flies showed cannibalism, and green dye accumulated in their abdomens. Interestingly, when they were given colored agar, they did not aggregate.

Fortunately, houseflies are hardy and can survive without food for about two weeks. A fly’s lifespan is approximately a month, but if it’s trapped in an air-conditioned room, it can live up to three weeks.
