Lost River Cave is nearing the end of its fundraising campaign for the continued support of the Charlie Miller Butterfly House. According to Lost River Cave Annual Giving Manager Kate Holmes, the butterfly habitat, which is open from sunrise to sunset every day from Memorial Day to Labor Day, requires roughly $20,000 each year in order to fund it and provide the opportunity for visitors to interact with and learn about the insects. So far, around 95 percent of this year's funding campaign has been raised, with approximately $3,300 remaining. If interested in donating to the butterfly habitat, visit lostrivercave.org/butterfly or the Lost River Cave Facebook page. Holmes said each person to donate will be invited to the habitat to help release a butterfly.
