The Regal Fritillary is considered a Pennsylvania invertebrate species of immediate conservation need.”As one of the busiest National Guard Training Centers in the country, Fort Indiantown Gap is also a leader on the environmental forefront because we place a very high priority on being environmentally aware,” said Lt. Col. Robert Hepner, commander of Fort Indiantown Gap. “These butterfly tours, given by our biologists, provide excellent insight on not only the regal fritillary butterfly but also on the flora, fauna, and wildlife that inhabit beautiful Fort Indiantown Gap and our dedication to safeguard these spectacular natural resources.”
