Provincial Butterflies of Sri Lanka

Provincial Butterflies of Sri Lanka are considered flagship species. Sri Lanka is home to a rich diversity of butterflies. The island hosts 245 butterfly species, of which 23 are endemic. Among them, 76 species are considered nationally threatened, mainly due to habitat loss, environmental degradation, and pollution. In response to these challenges, the government has taken an important step to promote butterfly conservation.

What Are Provincial Butterflies?

To raise awareness and promote regional conservation, Sri Lanka has named nine butterfly species as Provincial Butterflies—one for each province. These butterflies are:

  • Endemic to Sri Lanka
  • Not harmful at any life stage
  • Free from negative cultural or spiritual beliefs
  • Visually attractive and easy to spot

The Butterfly Expert Group, under the Biodiversity Secretariat of the Ministry of Environment and Renewable Energy, selected these species after careful evaluation.

Why Choose Butterflies?

The Butterflies are flagship species. Their bright colors and delicate beauty attract attention, making them ideal ambassadors for conservation. By linking each province with a unique butterfly, researchers aim to build a stronger regional identity and encourage local pride and protection of butterfly habitats.

Sri Lanka’s National Butterfly

In addition to provincial butterflies, Sri Lanka has also declared a National Butterfly—the Sri Lankan Birdwing (Troides darsius). It is the largest butterfly on the island and a symbol of the country’s natural heritage.
