The Science Museum of Western Virginia received approval on Monday from the United States Department of Agriculture to order and eventually display exotic butterflies in the museum.
The government regulates insects that come in from other countries. The approval process has taken about a month. The butterfly building needed modification before it could pass inspection.
Right now, the museum showcases four of the seven butterfly species native to the United States.
About 150-200 butterflies are on display at the museum.
"We need about twice that amount for the garden to be really full and hopping," says Jim Rollings, executive director of the museum.
The expectation is that the exotic butterflies could be flying around in the next two to three weeks if everything goes as planned.
