Lifespan Of A Horse Fly

Lifespan Of A Horse Fly


Horse flies are very large flies that are often brown, gray, or black with various markings. They have a very painful bite because of their spiked mouthparts that help them feed on blood. The females will bite the animals to get blood for reproduction purposes. The horse fly species is found throughout the world and they can be a serious pest in some areas.

There are different types of horse flies that have different sizes, markings, and behaviors. In this article we will look at the average lifespan of a horse fly and what factors contribute to it.

The lifespan of a horse fly depends on the gender and the species.

There are many factors that can affect the lifespan of a horse fly. The main factor is whether the horse fly is male or female, as males tend to live longer than females of the same species. For example, males of Culicoides sayi (a North American species) have been found to live up to two months while female C. sayi can only live for about one month.[1] Other factors include where you live and what time of year it is; horse flies tend to live longer in warmer climates like Florida than in colder ones like Colorado.[2]

Without blood, they will die out in between two to three weeks.

Horse flies need blood to survive. Without blood, they will die out in between two to three weeks. They will not lay eggs without blood and they will not be able to reproduce. They also won’t be able to survive or live because they do not have access to the nutrients that are needed for their survival.

Males tend to live longer than females.

  • In general, male horse flies tend to live longer than females. This is because males are more aggressive and expend a lot of energy flying around, so they are more likely to be predated on by birds or spiders. Females spend their time laying eggs, so they have less opportunity for being eaten.
  • Horse fly larvae can be found in water or in manure-filled soil (they feed on bacteria). Larvae may also be found under rocks at the edge of streams or ponds as well as under damp leaves on land or in woodsheds where they can easily feed off animal waste left behind by humans.

The males will still eat during this time but they won’t feed on blood.

The males will still eat during this time but they won’t feed on blood. They will eat nectar and other food sources, including some flowers, rotting meat, garbage, rotten fruit or vegetables and decaying fish.

They are inactive in the winter months unless it isn’t too cold outside.

Horse flies are active year-round with the exception of winter. They will spend the winter months hiding in cracks and crevices, or under logs and rocks where it’s safe from predators. If it isn’t too cold outside, they can also be found outside during this time as well. In warmer weather, horse flies are active all year long except for rainy days. In fact, you can expect to see a lot more horseflies buzzing around during these times when there is plenty of fresh water for them to drink from!

During their lifetime, they will travel up to fifty miles looking for food and water sources.

During their lifetime, they will travel up to fifty miles looking for food and water sources. In searching for food and water sources, they are able to survive as long as they can find them.

Horse flies have different lifespans depending on their gender and species

Horse flies are unique insects in that their lifespan is dependent on the gender of the fly. The female horse fly will live between two and three weeks, while the male horsefly’s lifespan is between two and three weeks. During this time, both genders will feed on blood or nectar and pollen depending on the species of horse fly.

The processes involved with feeding include slowing down their metabolism to keep from attracting predators or being seen by other animals, such as humans being bitten by mosquitoes at dusk when it’s dark outside so they aren’t able to see them as well as during daylight hours where there are fewer distractions from sunlight reflecting off shiny surfaces like lakes or ponds throughout North America where water levels have dropped due to drought conditions due to climate change which means there isn’t enough rain during certain times of year causing everyone who lives near lakes or ponds nearby these areas like San Diego County California which has been hit hard by wildfires burning through thousands upon thousands acres every day since late December 2015 until now (February 2016).


Horse fly larvae have a lifespan of about one year before they become pupae, which then emerge and turn into adults. The females die shortly after giving birth to their eggs while males will live longer because they aren’t as active in their search for food and water sources as females are.
