Denmark is home to a surprising diversity of butterflies— more than 2,500 butterfly species have been registered, most of which are nocturnal moths.

In the countryside, during summertime, you can see species fluttering through meadows, forests and coastal areas. From the magnificent Silver-washed Fritillary to the delicate Common Blue, these winged wonders are a sign of a healthy and thriving environment.
Unfortunately, not all species are doing well. Many are in decline, endangered or vulnerable. Some have disappeared. Only about 70 species are diurnal butterflies, which are active during the day.

Across the country, authorities, volunteers and nature conservation associations are working to help butterflies. Even in many small private gardens, there is now a focus on helping butterflies and wild bees.
Amazing caterpillars
But before they become butterflies, they begin life as caterpillars. These leaf-munching larvae are vital to the ecosystem, serving as food for birds and other animals while helping plants by encouraging new growth.
Caterpillars can be surprisingly beautiful and distinctive in appearance and color. Many gray and perhaps somewhat dull moths are extremely colorful during their time as a caterpillar.

Did you know? Many caterpillars in Denmark rely on native plants like nettles, buckthorn, and clover to survive. Supporting wildflower growth helps butterfly populations thrive.
Keep an eye out in summer months—May to late August is peak butterfly season. Whether you’re walking through heathland, coastal dunes, or a city park, there’s always a chance to spot one of nature’s tiny masterpieces.
