Call them fireflies or lightning bugs, but are there fewer in Indiana than in the past?

Chasing lightning bugs on a summer night is a rite of passage for many young Indiana residents.
In fact, Indiana's state insect is a lightning bug.
There are about 40 species of what are called Lampyridae, or light-emitting beetles, in Indiana and more than 1,900 types worldwide. They've been around for millions of years, but some Hoosiers say it feels like they're seeing fewer flashes across the night sky than in the past.
Lightning bugs or fireflies: What are those glowing insects called?
So, are lightning bugs disappearing from Indiana?
'If we go from qualitative assessment alone, they seem to be on the decline,' said Sérgio Henriques, who serves as the Invertebrate Conservation Coordinator for the Indianapolis Zoo's Global Center for Species Survival.
Part of the problem, however, is that there isn't adequate data on lightning bugs to speak with specificity. Researchers across the country, like Henriques, are working to gather more information and assess the threat of extinction.
'It's complicated and it depends on the species,' Henriques said of the level of threat. 'But overall, they're not doing great.'
There are several reasons why fireflies are at risk. The first is an issue that plagues many struggling species: loss of habitat.
Fireflies do well in areas with some moisture and humidity — they often live near ponds, streams, marshes, rivers and lakes or in the margins where these areas meet fields and forests. However, development and climate change are shrinking places where they survive.
They also are suffering because of light pollution.The firefly's light is like a whisper, Henriques said, 'while our lights are really loud in comparison and drown them out.'
Fireflies have a lifespan of just a couple months. All the lights at night disorient them and can interfere with their ability to find a mate.
Scrub Hub: Is there a good turf grass replacement that's dog-friendly and low- or no-mow?
One of the other main threats comes from chemicals: The use of pesticides and herbicides on lawns can wreak havoc on fireflies.
Henriques said there are 'little and easy' things Hoosiers can do to help lightning bugs. He suggests reducing lights at night, planting native species or installing a rain garden. Another option: reducing the chemicals you use on your yard or in your house.
'Fireflies are a privilege,' he said. 'It would be such a waste of a treasure if they were to decline or be gone.'

When is the full moon in June? Strawberry moon in Indiana will be a sweet sight
The month of June is going to be a sweet feast for Indiana skywatchers. Not only can Hoosiers witness the Strawberry Moon but also the Milky Way, "the bright central bulge of our galaxy," writes NASA, which should be visible through August. Here are some quick facts about the Strawberry Moon that skywatchers can snack on as it soars across the heavens. Wednesday, June 11, 2025, is when the sweet Strawberry Moon shines in the night sky. The moon's phases in June are: According to the Old Farmer's Almanac, moonrise for the Indianapolis area will happen by roughly 10:09 p.m. Wednesday, June 11, crossing the meridian at 1:38 a.m. before setting at 6:01 a.m. Thursday. You can check moonrise and moonset times for your zip code by visiting the Old Farmer's Almanac online. Story continues after photo gallery. Skies around Indianapolis are predicted to be mostly clear Wednesday night, June 11, with a low of around 60, according to an advanced forecast from the National Weather Service. Similar to the Pink Moon, June's Strawberry Moon takes its name from seasonal plant growth, according to the Old Farmer's Almanac. Many ripening berries were ready to be harvested around this time in the northeastern United States. Other names for June's full moon from Native American tribes include the Birth Moon, Hot Moon, Blooming Moon, and the Green Corn Moon. The Milky Way can best be viewed somewhere far away from bright city lights. Beverly Shores, near Gary, is an International Dark Sky location and therefore an excellent place for stargazing. You can also travel to Kemil Beach at Indiana Dunes State Park and Dr. T.K. Lawless County Park in Michigan, which also are designated dark sky locations, according to DarkSky International. According to NASA, traces of the Milky Way will appear as a "faint, cloud-like band arching across the sky toward the south." If you plan on observing the night sky this month, writes NASA, keep the following dates in mind for June 2025: The following free astronomy apps can help you locate stars, planets, and constellations. The full Buck Moon should reach peak illumination by Thursday, July 10, 2025. When is the next full moon?: When every full moon shines in 2025. Dates, times and the history behind each name.
