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

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

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.

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.
