Butterflies are notable for their unusual life cycle with an egg stage, a larval caterpillar stage, an inactive pupal stage, and a spectacular metamorphosis into a familiar and colourful winged adult form.

In this stamp issue, 4 butterfly species in Singapore, namely the Blue Glassy Tiger, the Common Birdwing, the Common Posy and the Tailed Jay are beautifully illustrated and featured.

This stamp issue preludes the upcoming Butterfly Trail at Orchard Road. Spearheaded by the Nature Society (Singapore), supported by the National Parks Board and Singapore Environment Council, the 4km long trail starts at the gates of the Botanic Gardens, continues down Orchard Road and ends in Fort Canning Park.

The trail is being billed as the first of its kind in the world and visitors will get specially produced maps to help them navigate and guide them to the butterfly hot spots.
