Understanding the British Swallowtail

The British Swallowtail (Papilio machaon britannicus) is a subspecies of the Swallowtail butterfly found exclusively in the UK, primarily in the Norfolk Broads. It’s a sight to behold, with its large size, vibrant colours, and elegant flight. But what makes it so special, and why is it in need of our help?

Why the British Swallowtail is Unique

Endemic Subspecies: The British Swallowtail is unique to the UK, making it a vital part of our natural heritage.
Habitat Specialist: Unlike other Swallowtail subspecies, it relies almost entirely on milk-parsley (Peucedanum palustre) as its larval food plant.
Restricted Range: Its distribution is limited to the Norfolk Broads, a unique wetland ecosystem.

Threats to Their Survival

Several factors threaten the British Swallowtail, including:

Habitat Loss: Drainage and changes in land management have reduced the availability of suitable habitat and milk-parsley.
Climate Change: Changing weather patterns can disrupt their breeding cycle and affect the availability of their food plant.
Collection: Although illegal, the collection of Swallowtails still occurs, further reducing their numbers.
Pesticide Use: Pesticides can directly harm the caterpillars and reduce the abundance of insects that the adult butterflies rely on for nectar.

How You Can Help with British Swallowtail Conservation

Adult butterflies need nectar for energy. Choose a variety of flowering plants that bloom at different times of the year to provide a continuous food source. Some excellent choices include:

Buddlejas (Butterfly Bush)
Lavender
Sedum
Echinacea
Verbena

Provide Caterpillar Food Plants

While you may not be able to grow milk-parsley outside of its natural range, you can provide food plants for other butterfly species. This will attract more butterflies to your garden, creating a richer ecosystem. Some options are:

Nasturtiums (food plant for the Large White butterfly)
Fennel (food plant for the Swallowtail butterfly – if you live in an area where they occur)
Thistles (food plant for the Painted Lady butterfly)

Avoid Pesticides

Pesticides can harm butterflies and other beneficial insects. Opt for organic gardening methods and encourage natural predators like ladybugs and lacewings to control pests.

Provide Shelter and Water

Butterflies need shelter from wind and rain, as well as a source of water. Plant shrubs and trees to create sheltered areas, and provide a shallow dish of water with pebbles for them to land on.

3. Plant Milk-Parsley (If You’re in the Right Area)

If you live in or near the Norfolk Broads, planting milk-parsley in your garden or on suitable land can directly benefit the British Swallowtail. However, it’s crucial to consider a few key factors:

Is Your Location Suitable?

Milk-parsley thrives in damp, marshy conditions. It’s essential to ensure that your garden or land provides the right environment. Check with local conservation organizations for advice on suitable locations.
