Did You Know?

Adult wingspan is typically 3.2-4.7 cm; the Large White butterfly is larger, usually 5.0-6.5 cm (Scott, 1986).

Males usually show one black forewing spot; females typically have two, a key field mark in gardens.

Eggs are laid singly on brassica leaves; hatching commonly occurs in ~4-8 days, temperature dependent (CABI datasheet).

Larvae feed mainly on Brassicaceae-cabbage, kale, mustard, radish, shepherd's purse-using mustard-oil chemistry to locate hosts.

It overwinters as a chrysalis (pupa); adults may live about 2-3 weeks, longer in cool conditions (various rearing studies).

Introduced to eastern North America in the 1860s and spread across the continent within decades alongside agriculture (historical records).

Many regions see multiple broods: often 2-3 per year in cool temperate climates, rising to 5+ in warmer areas (regional butterfly atlases).

Unique Adaptations

  • Larvae tolerate and sequester glucosinolates from brassicas, chemicals that deter many other herbivores.
  • Specialized chemosensory receptors help adults detect host-plant compounds, improving egg-laying accuracy on Brassicaceae.
  • Fast, multi-generation life cycle allows quick population rebounds after disturbance in farms and gardens.
  • Cryptic green larvae with a pale dorsal line blend into cabbage leaves, reducing detection by visual predators.
  • Light-colored wings reflect heat, aiding activity in open, sunlit habitats like fields, roadsides, and gardens.

Interesting Behaviors

  • Females "drum" leaves with forelegs, tasting chemicals before placing a single egg on a suitable brassica.
  • Adults bask with wings partly open, using sunlight to warm flight muscles for rapid takeoff.
  • Males patrol low over fields and gardens, repeatedly investigating moving white objects as potential mates.
  • Caterpillars feed mostly by day, chewing irregular holes and often hiding along midribs between bouts.
  • Pupae attach upright with a silk girdle; many enter diapause to survive winter as chrysalids.

Cultural Significance

Often the "white butterfly" of gardens, Pieris rapae is both a beloved childhood nature-study insect and a major brassica pest, shaping home-gardening advice and agricultural monitoring worldwide.

Myths & Legends

In Japanese tradition, butterflies can be souls of the living or dead; a white butterfly is sometimes read as a visiting spirit.

In parts of Europe, white butterflies in spring were treated as omens of fair weather and the season's luck in fields.

Greek tradition personifies the soul as Psyche, often shown with butterfly wings; butterflies symbolize the soul's journey and transformation.

Victorian-era symbolism commonly treated butterflies as emblems of change and fleeting life, imagery often applied to common garden whites.

The white butterfly lives all over the world including Australia, Asia, and Europe. There are a total of 1,100 species of white butterflies worldwide. They are found in gardens, forests, and traveling over fields of weeds. Their bright, white wings and black spots make them hard to miss! They survive on a diet of nectar from flowers or pieces of fruit. This butterfly is known as the cabbage white butterfly in North America.

4 Incredible White Butterfly Facts!

  • This insect has special sensors on its feet that tell it whether a flower has nectar.
  • These insects have a wide range of symbolism attached to them. They can symbolize good luck, an upcoming rainy season, or even death.
  • The cabbage white butterfly was introduced to the United States back in the mid-1800s.
  • A male gets the attention of a female cabbage white butterfly by flying in a zigzag motion.

Scientific Names

The white butterfly belongs to the Pieridae family of which there are 1,100 species of white butterflies. The Pierdiae is part of the larger and more vast order Lepidoptera, of which there can be found around 180,000 species.

Types Of

A few types of white butterflies commonly seen in gardens include:

  • Green-veined white butterfly (Pieris napi) – Streaked (greeny-grey lines following the wing veins radiating out towards the wing’s outer edge)
  • Large white butterfly (Pieris Brassicae) – Plain (a creamy-white color, no obvious markings)
  • Small white butterfly (Pieris rapae) – Plain (a creamy-white color, no obvious markings)
  • Orange-tip white butterfly (Anthocharis cardamines) – Blotchy (greeny-grey camouflage pattern all over the wing); males have bright orange wing-tips.

Evolution And Origin

It is believed that the butterfly’s ancestors evolved simultaneously as flowering plants. Its oldest common ancestor, the moth, in the order Lepidoptera, was present about 300 million years ago, during the Carboniferous Period. However, butterflies didn’t begin to evolve from moths until 100 million years ago and the most contributing factor to this change was due to natural selection in the way they were able to eat. Since moths had developed straw-like jaws, they were able to profit from the natural food source of the nectar from the plants and flowers, eventually leading the change from moth to butterfly.

Appearance

isolated white butterfly

The white butterfly appears to be pure white but has distinct markings.

The cabbage white butterfly has a wingspan of 1 ¾ to 2 ¼ inches. Though at first glance it looks to have pure white wings, the underside of its forewing and hindwings are pale yellow. Both males and females have black spots on their wings, but there’s a difference. A male has one black spot on its forewing while a female has two.

They have two antennae with a club or a black tip at the end of each one. Their body has three sections: head, thorax, and abdomen. They have six legs, four long ones, and two short ones. When comparing a white butterfly to a white moth, you’ll see the moth is smaller. A white moth has a smaller wingspan.

The largest of this species is the Large white butterfly with a wingspan of up to 2.7 inches.

Camouflage is one way this insect protects itself against predators. Of course, this is a bright, white butterfly, so it would have to find a gathering of white flowers to blend in. One of the types of white butterflies, namely the green-veined white, can blend in a little easier with flowers and plants that are both green and white.

The cabbage white butterfly is solitary unless it’s breeding time. Occasionally, they can be found flying near other white butterflies.

Habitat

White butterflies are partial to gardens but are found in forests and parks.

White butterflies are originally from Europe. But, they have spread to other places around the world such as Australia, Asia, Africa, and North America.

Some cabbage white butterflies are partial to a garden habitat. Others are seen traveling through weeds near roadsides and in parks. Forests are another habitat for these adaptable insects. If they find their way inside a home, it’s purely by accident.

Diet

White butterflies don’t have a mouth, so they don’t chew food. Instead, they have a proboscis which is like a slim drinking straw they use to draw liquid into their body. They spend most of their day moving from flower to flower to get nourishment.

What Eats White Butterflies?

Spiders, birds, and wasps are among the predators of white butterflies. All three of these predators live in a habitat close by.

What Do White Butterflies Eat?

Cabbage white butterflies drink nectar from flowers or fruit as sustenance. The butterfly lands on a flower and uses the sensors in its feet and antennae to determine whether the plant has the type of nectar it wants to drink. This is one of the ways it protects itself from taking in liquid that’s dangerous to its health.

Prevention

White butterflies have the potential to cause problems in gardens.

While these butterflies aren’t a pest inside a home, they can be pests in a homeowner’s garden. Though a butterfly moving through a garden and drinking nectar is harmless, they have the potential to create a problem. In short, these butterflies may lay eggs. The eggs hatch into cabbageworms. These cabbageworms eat a lot of items in a garden including cauliflower, broccoli, kale, and, of course, cabbage. If a gardener doesn’t see actual cabbageworms, there is clear evidence of their presence. These pests make tiny holes and tears throughout the leaves of cabbage and other vegetable plants.

To get rid of cabbageworms, some people go through and look for eggs left behind by butterflies so they can remove them. These butterflies lay their eggs on the underside of the leaves of cabbage and other plants. Cabbageworm eggs are oblong, yellow, and about one millimeter long. Look closely enough and you’ll notice there are ridges on the sides of the eggs. There can be large clusters of them located under a leaf. The female butterfly lays the eggs there purposely, so the cabbageworms will have plenty to eat!

Another way to get rid of cabbageworms is with cornmeal. When a cabbage plant is wet, sprinkle it with cornmeal. The cabbageworms overeat the cornmeal and die. Putting up special butterfly netting can also prevent cabbage white butterflies from getting close enough to a garden to lay eggs. Plus, the netting doesn’t capture the butterflies. They just move on.
