Butterflies are a group of common insects well known to everyone. They are easily recognised by their diverse colours. Butterflies have beautifully colored wings which are covered in hundreds of thousands of tiny scales. The colors are determined by the layering and overlapping of the scales.
Butterflies are placed in the Order Lepidoptera, (Lepidoptera: Lepido –Scaly, Ptera -Wings). Two hundred and forty four(245) species of butterflies are recorded in Sri Lanka of which twenty one (25) are endemic. Butterflies are indicators of a healthy environment and healthy ecosystems.
