To identify a Large White butterfly, look for a medium-to-large-sized butterfly with white wings and black markings. The black tips on the forewings and few black spots on the hindwings are key features to distinguish them from other white butterfly species.
Lifecycle and Breeding Habits
Eggs and Caterpillars
Female Large White Butterflies lay their eggs on host plants, typically among cabbages and other cruciferous vegetables. For example:
- Cabbage
- Brussels sprouts
- Broccoli
The eggs are yellowish and laid in clusters. After hatching, the caterpillars feed on the host plants, growing and molting several times.
Adults and Mating
Large White Butterflies undergo a complete transformation, emerging as adults in the springtime. Adult characteristics include:
- Wingspan: 5-7 cm
- Colors: White with black tips on forewings
Males and females find mates through a courtship display, where the male hovers above the female, releasing pheromones to attract her. Adults have a few mutual characteristics:
- Lifespan: 3-4 weeks
- Diet: Flower nectar
| Female | Male |
|---|---|
| Size: Slightly larger | Size: Slightly smaller |
| Extra black spot on forewings | No extra black spot on forewings |
Multiple Generations in a Year
In suitable habitats, Large White Butterflies can produce multiple generations within a year. For example, in the US, there may be up to three generations per year. Each generation overlaps, with eggs, caterpillars, and adults present simultaneously.
Behavior and Distribution
Feeding Preferences
Large White Butterflies caterpillars feed primarily on plants in the cabbage family, like:
- Garlic mustard
- Broccoli
- Cauliflower
Adult butterflies, on the other hand, search for nectar from various flowers to fuel their flight.
Finding Suitable Habitats
These butterflies prefer habitats that include:
- Gardens
- Hedgerows
- Woodland edges
They can be found at various altitudes, from sea level up to 2,000 meters in some parts of their range.
Geographical Distribution
| Country | Presence |
|---|---|
| Britain | Widespread |
| England | Common |
| Ireland | Common |
Large White Butterflies are commonly found throughout Britain, England, and Ireland. They have adapted to various environments and can be observed in rural and urban areas alike.
Host Plants and Gardens
Cabbage and Brassicas
Large White Butterflies (Pieris brassicae) primarily lay their eggs on plants within the cabbage family (Brassicaceae). Some common examples include:
- Cabbage (Brassica oleracea)
- Kale
- Oil-seed rape
- Wild Mignonette (Reseda lutea)
- Sea kale (Crambe maritima)
These caterpillars can cause significant damage to these plants, especially in allotments and gardens.
Attracting the Large White Butterfly to Your Garden
If you’d like to attract Large White Butterflies to your garden, consider planting some of their preferred host plants. Some suggestions are:
- Tropaeolum majus (nasturtiums)
- Brassica oleracea (cabbage family)
To further entice them, ensure your garden has:
- Sunny, sheltered areas
- A variety of nectar-rich flowers
Host Plants and Protection
Balance attracting Large Whites with protecting your cabbages and brassicas. Some strategies include:
- Planting sacrificial plants like nasturtiums to distract them from your cabbage crop
- Covering brassicas with fine mesh/netting to prevent egg-laying.
In summary, to create an ideal environment for Large White Butterflies, provide their favorite host plants and protect your prized crops with barriers like fine mesh or by using sacrificial plants. Remember to keep your garden sunny, sheltered, and full of nectar-rich flowers.

Threats and Predators
Common Predators of Large White Butterfly
Large white butterflies face numerous predators in their lifetime. Some common predators include:
- Birds
- Spiders
- Wasps
- Beetles
These predators target all life stages of the butterfly, from eggs to larvae to adults.
Comparison of Large White Butterfly with other butterfly species:
| Species | Predators | Size | Habitat |
|---|---|---|---|
| Large White Butterfly | Birds, spiders, wasps, beetles | 5-6.5 cm | Gardens, meadows, hedgerows |
| Green-veined White | Birds, spiders | 4-5 cm | Woodlands, meadows, hedgerows |
| Orange-tip | Birds, ants | 4.5-5.5 cm | Grassy habitats, hedgerows |
| Swallowtail Butterfly | Birds, ants | 7-10 cm | Wetlands, marshes, riverbanks |
Protecting Caterpillars from Predators
Caterpillars of large white butterflies have several strategies to protect themselves from predators:
- Camouflage: Caterpillars have a well-developed color pattern that helps them blend in with their surroundings.
- Feeding on toxic plants: Eating toxic plants like cabbage and mustard allows the caterpillar to accumulate chemicals that deter predators.
- Hiding: Caterpillars often hide under leaves during the day, minimizing exposure to predators.
In order to support large white butterfly populations in the north east, consider planting host plants (e.g., cabbages, mustard) and providing cover in habitats like gardens, meadows, and hedgerows. This will give the caterpillars food and shelter, helping them avoid predation.
