A 'Valley of Butterflies' is coming up on the outskirts of the city to house 42 varieties of the winged creatures found in Jharkhand.

"Two acres of forest land have been identified in the 542-acre biodiversity park at Lalkhatnga, 20 km from here, for creating the butterfly park," said a senior officer of the Indian Forest Service and entomologist R P Singh.

He said the idea had been borrowed from the Kerala State Research Institute, which created the design for similar parks in the southern state. The project will be completed by next December.
