How Long Do Butterflies Live In Australia

The lifespan of butterflies differs widely and is dependent on numerous factors. The butterfly’s size, type, habitat, and maturation season, among other factors, depends. For instance, a little butterfly will likely not survive as long as a bigger butterfly, which will live longer overall. Of course, the size of the butterfly will not be the only determinant in determining how long it will survive, but it does contribute.

How Long Do Butterflies Live In Australia? Butterflies spend an average of two months in Australia because they must reproduce during that time before returning to their home country. However, outside variables like the environment and predators could impact this time.

There are 400 different butterfly types in Australia, and each butterfly depends on extremely specialized settings, such as particular plants for reproduction or specific weather. Here is a glance at some of the spectacular butterfly species found in Australia.

Butterfly Monarch

The Monarch butterfly, one of the most well-known species, is native to North America and was first discovered in Australia in the 1870s.

Australia and the Pacific Islands support a sizable breeding population of monarch butterflies. Additionally, they have a top speed of 40 kilometres per hour.

Female butterflies lay solitary eggs under the leaves of milkweed plants all summer long. The freshly emerged caterpillars are deadly to predators because they eat the plant’s milky sap. Potential predators are attractively warned by the caterpillar’s patterns that indicate their toxicity.

The season in which a monarch egg hatches determines how long it will live. While summer generations only endure for about 5 weeks, winter generations can last up to 8 months.

Varied Eggfly

Likewise known as the Blue Moon butterfly. Female butterflies will carefully consider a plant that doesn’t have ants. After that, they will protect the plant and lay up to five eggs on the underside of the leaves. The male butterflies are fiercely possessive animals. They like feasting as caterpillars on exotic weedy plants like joy weed and love flowers.

Blue Tiger Butterfly

The Blue Tiger butterfly can be seen year-round in North Queensland, although it migrates south in the spring and summer.

Did you realize? To avoid being eaten by birds, the Blue Tiger butterfly larvae consume their host plant, the Corky Milk Vine, which is poisonous to many other creatures. The poisons are then transferred to the pupae and adult butterflies. They have a six-month life span as butterflies.

Orchard Swallowtail Butterfly 

Another name for it is the enormous Orchard butterfly. Even though they have rather big wings, researchers have discovered that their flight patterns are slow and erratic. Both female and male butterflies have an adult lifespan of three months.

The Orchard Swallowtail caterpillar prefers eating native members of the citrus fruits, Rutaceae family, and fresh, juicy leaves.

The Cairns Birdwing Butterfly

These butterflies, the biggest in Australia and may reach a width of 18 cm, are also known as the Cooktown birdwing and the northern birdwing. The female butterfly is typically black and white, while the male is typically black, gold, and green. Only up to five weeks are typically spent by these butterflies in their butterfly condition.

The dull-brown Birdwing caterpillars have black and orange spikes with venom that serve as a deterrent to attackers before they reach the chrysalis.

Why do butterflies migrate?

Butterflies move south to avoid the harsh winter. They take off southward in search of food and shelter in warmer climes. A normal activity that has been going on for centuries is migration. Additionally, during this time, they reproduce.

Due to concerns from human activity such as deforestation, climate change, and other challenges, it is now recognized that this voyage is among the most hazardous for the butterflies. Global warming has resulted in warmer conditions in several locations.

As a result, butterflies are surviving and thriving. The weather is getting colder and wetter in other nations, though. Due to the terrible circumstances at their original site, they are compelled to travel once more or perish.

Butterflies have a top speed of 25 mph and a range of up to 2,000 kilometres. They often stay in Australia for two months on average since they need that time to be able to spawn before taking off for their native country.

When do butterflies hatch in Australia?

Clusters of the Australian painted lady butterfly emerge in the spring and persist until late fall in Australia, when the butterflies split up after mating. The females depart first, travelling to new growth in the spring to lay their eggs.

The Australian coloured lady butterfly spends the winter months in the Australian bush, where it feeds on wildflowers and lays eggs that develop into larvae that well in nests constructed of leaves and silk.

Depending on the conditions, the Australian Painted Lady Butterfly can produce several generations in a single year. The butterfly can survive for nine months in southern Australia, where the winters are mild. The butterflies only survive for a short time in northern Australia because the winters are shorter and drier.

Butterfly Facts

The main aviary can be divided into three sections: the nectar and egg area, the emergence cages, and the egg-laying area. All of these are utilized during the life cycle.

A butterfly’s time to attain full maturity varies depending on the species and is influenced by the climate. The butterfly can start mating once it has reached adulthood. The male must entice the female before mating can begin. Typically, the male does this while flying in circles around the female and emitting pheromones.

Other butterfly species, such as the Silky Hairstreak and the Imperial Hairstreak, which are drawn to the larvae by secretions, coexist harmoniously with ants.

A butterfly’s lifetime is typically two weeks. However, certain species, like the Mourning Cloak, can live for up to 11 months (a North American butterfly). In Australia, the Blue Tiger Butterfly can survive up to six months and the Monarch Butterfly up to eight months throughout the winter.


Butterflies in Australia live for about two months on average. Naturally, overlapping factors—like weather, predators, or being unable to reproduce before they fly back home—can either increase or decrease their longevity.
