Why do butterflies visit gardens?
A variety of different butterflies visit our gardens looking for food, places to breed, or spots to overwinter as adults, larvae or pupae. Each garden will attract a different set of butterflies depending on the plants, trees and shrubs present, and what the surrounding habitats are like.
Why are gardens important for butterflies?
Over recent years, many of our once-common butterflies have declined dramatically in number due to increased development, agricultural intensification, habitat loss and climate change; for instance, the small tortoiseshell has decreased by a massive 80% in South East England since 1990. But butterflies do have a lifeline. Together, the 16 million gardens across the UK form an area for wildlife larger than all our National Nature Reserves. This patchwork of habitats helps our wildlife to move about freely, forming a vast living landscape that links urban green spaces with the wider countryside.
Which butterflies am I likely to see in my garden?
The following butterflies are some of the common species spotted in gardens. An overcast day is a particularly good time to see them up close because they won't be as active and stay still for longer!

Description: Black with broad, red stripes on the hindwings and forewings, and white spots near the tips of the forewings.
Description: Orange with black tips to the forewings that are adorned with white spots, and black spots on the hindwings and forewings.
Description: Reddish-orange with black and yellow markings on the forewings and a ring of blue spots around the edge of the wings.

How can I encourage butterflies to visit my garden?
Whether you have a small, city patch or acres of fields, you can encourage butterflies to visit your garden.
- Plant nectar-rich flowers and shrubs like buddleia, ivy, daisies, verbana, forget-me-not, heather, lavender and primroses for them to feed on throughout the seasons – even a few flowers in a windowbox will do the trick!
- Provide places for overwintering insects, such as piles of logs or leaves, climbing ivy or shrubs, or an ornamental butterfly house. You might find that small tortoiseshell and peacock butterflies try to overwinter in your cosy, warm house. If you find one that’s woken up when it’s still very cold outside, gently take it to a cool shed or outhouse, so it can head back into dormancy.
- While most caterpillars are welcome in the garden, those of the large and small white butterflies (the ‘cabbage whites’) are famed for damaging vegetables. If they do become a pest, don’t use harmful pesticides, but try placing horticultural fleece over your crop to protect it.
