Discover Life in America (DLIA) is holding a number of events this summer for the public to experience the synchronous fireflies that illuminate the Great Smoky Mountain National Park during the first weeks of June.

A fundraising event will be held from 7:30 p.m. to 11 p.m. on June 10 and June 11 at Norton Creek Sanctuary near Gatlinburg. Participants will be able to view and learn about synchronous fireflies and ask questions to a firefly expert on site. Heavy hors d’oeuvres, beer and wine will be provided. There will be a short walk to the site. $75.

The annual Firefly Festival will be held from 11 a.m. to 4 p.m. on June 11 at the Nantahala Outdoor Center Great Outpost in Gatlinburg. It is a free event open to the public with live music provided by Captain Firefly, as well as artwork, an insect zoo, kids’ activities, food and drink vendors, a bioluminescence room and two synchronous firefly presentations.

Another firefly presentation and picnic will be held from 7:30 p.m. to 11 p.m. on June 12 at the Park Grill. After the presentation, food and drink, participants will carpool to a secret site in the park. There will be a short hike, and guests should be prepared for inclement weather. $50.
