Why Do Butterflies Die So Fast?

Butterflies are the little sensitive creatures that add color and life to your lifeless garden if you plant flowers to attract them. However, these pretty and colorful insects do not live longer.

Why Do Butterflies Die So Fast? Butterflies die so fast because of predator attacks, sudden climate changes, habitat loss, size, pesticides on plants and crops, and investing energy in successful reproduction. The average lifespan of a butterfly is 14-28 days in adulthood after emerging from the chrysalis stage, and it can vary for different species and environmental conditions. Some species can live more than a year, while others die in a few days.

They can help the flower garden to grow by transferring the pollens. They draw the attraction of anyone sitting in the garden and observing their behavior due to their bright appearance and sensitive nature. Different species live in different habitats and continue to increase their population.

Why do butterflies die so soon?

Butterflies are found all around the world, with more than 1700 species, and approximately 750 butterfly species are in the United States.


There are various predators of butterflies in wild and urban areas because they are easy prey for predators, and they attack them to fill their stomachs.

For example, birds, lizards, snakes, ants, dragonflies, toads, rats, frogs, wasps, and many rodents attack and eat butterflies.

These predators can attack the caterpillars or larvae in the developing stage and eat them rapidly before other birds or insects reach them.

Different insects can invade their habitat or the gardens where they live, which causes them to die soon before completing their lifecycle.

Environmental factors

Environmental factors, such as smoke, increasing air pollution, rainstorms, food scarcity, and temperature, can cause butterflies to end up soon.

They cannot survive harsh weather conditions and high temperatures because they cannot adapt to the high temperatures, which causes their death.

Moreover, high temperature causes dehydration, which causes a high metabolic rate and more energy consumption. The snowy and cold weather also causes problems for butterflies, as their bodies become slow and cannot forage food conveniently.

The eggs cannot hatch or complete the metamorphosis process until a warmer environment is provided. Therefore, the chances of egg destruction are more when climate changes suddenly.

These factors cause shorter lifespan, such as heavy rainfall or rainstorms, which reduces the nectar from flowers and can drown these little insects.

Habitat loss

Butterflies are more prone to the effects of habitat loss because they do not adapt easily to changing climates and habitats.

Natural disasters can disturb their life cycle and reproduction, and they cannot survive without food.

They can die during migration from one place to another when searching for suitable habitat. Excessive stress, resource shortage, and lack of habitat contribute to their shorter lifespan.

Moreover, the clearing of gardens and fewer plantations of flowers or plants in some regions due to urbanization can cause them to die soon due to fewer habitat options.

Successful reproduction

One of the primary purposes of adult butterflies is to find a mate and reproduce to increase their population. Once they mate and their female lays eggs, their life purpose is completed, and they die in peace.

Moreover, they invest much energy to complete the metamorphosis process, such as passing through four different life stages and entering adulthood.

It also causes them to have a shorter lifespan in adulthood because they cannot survive without energy in their bodies. They need continuous energy sources to forage food and take flights, and they die so fast if they do not get enough nutrients and energy to carry on their daily activities. 

Their genetic makeup causes them to live a short life in adulthood, as they spend more time and energy in metamorphosis.


The size of these insects also contributes to their lifespan; the small butterflies usually have short lifetimes compared to larger species.

For example, I have many butterflies in my garden, and all are of different sizes and species. I noticed that the smaller butterflies die sooner than larger ones because of their size and capacity to bear different situations.

Checkered White can only live for 7-9 days in adulthood due to its smaller size, while the Queen Alexandra bird wind butterfly is the largest and can live up to many months.

Pesticides on plants and crops

People use pesticides and medicines on plants and crops to increase their growth and keep insects and birds away.

These chemical products cause several health problems and habitat destruction, as they cannot eat the treated crops and plants and die due to food scarcity.

Farmers or landscaping owners use pesticides that affect the sensitive body organs, and they cannot live longer if they feed on these crops and plants.

Some species feed on the plant seeds and experience a short lifetime if they consume the chemicals in the food. Therefore, it is better to avoid spraying pesticides if you want to attract these pretty and colorful insects to your landscaping areas.

How long do butterflies live?

On average, butterflies can live 14-28 days in adulthood, or you can say they can survive two to four weeks after emerging from the chrysalis stage.

Different species have different lifetimes; some butterflies can live several weeks, while others die within a few days. It depends on the climate, predators, food resources, successful reproduction, and suitable habitats.

For example, the common blue butterfly can live up to 2-3 weeks because of high competition with other insects of the same species.

Moreover, European skippers can live 10-12 months because they lay eggs in winter and hatch in spring. Different species of Swallowtail butterflies live varying lifetimes, as an adult swallowtail can live 25-30 days, while a black swallowtail can last for 10-12 days. Their other species can live longer, such as 40-45 days under normal conditions.

In addition, scientists believe that butterflies in captivity can live longer than those in the wild because there are fewer predation risks and more suitable conditions are provided.

However, the experiments are not very successful, as there is not a significant increase in their lifespan, and scientists think the genetic makeup is the reason behind the shorter lifetime.

The lifespan in captivity is larger than in the wild because there are no predators, a controlled environment, and more food availability.

What butterflies have the shortest lifespan?

Coppers and small blues have the shortest lifespan among all butterfly species, such as they can live a few days in adulthood, depending on the environmental conditions and food sources.

They spend less time completing the metamorphosis process and immediately search for a mate for reproduction. The fast development allows them to have more chances of mating. However, the lifespan in adulthood shortens.

They have specific preferences for flowers to feed nectar; therefore, fewer food sources are responsible for their shorter lifetime than other butterflies that can feed on any plant and flower.

They are more prone to predator attack due to their bright appearance and small size, as birds and insects can conveniently notice and attack them.

What is the longest-living butterfly?

Brimstone and monarch butterflies can live longer than other species. Brimstone can live up to 12-13 months, and migratory Monarch butterflies can survive 9-10 months.

Brimstone butterflies are found in Asia, Europe, North Africa, and North England, and these insects hibernate in winter, contributing to their long lifetime.

They can forage food under suitable environmental conditions, reproduce, and survive small climate changes. They feed on plant sap, honeydew that aphids produce, and other sugar substances.

Their migratory behavior enables them to travel long distances and explore diverse habitats. They do not waste more energy on reproduction and focus on survival and finding food sources.

They are less prone to predator attacks because they use many strategies to avoid them, such as using zigzag flying patterns to escape potential threats.
