Butterflies thrive on flowering plants. The park will be of scientific importance and be a green area in Gurugram, Forests Minister Rao Narbir Singh said here.
The park's purpose is to conserve depleting species of butterflies because of the massive urbanisation in the area, an official release said.
It is being developed in association with an NGO, Uthaan, and construction will be completed in about a year, it said, adding that the facility will have an information-cum-demo center and a larvae and pupae area.
So far, about 15 indigenous species have been identified in a survey team in this area. The endeavour is to create a natural condition conducive for multiplication, it said.
The release said that this can be achieved by providing good host plants round the year and preventing pests from eating larvae and eggs.
