Can you keep fireflies inside

Yes, you can try to keep fireflies [Lampyridaefamily] inside. But chances are strong that they won't do well or survive. Lightning bugs are very social nocturnal insects. That means that they spend their nights flying around after prey or with others of their own kind.

As beetles, the outer set of a firefly's wings is heavier and for balance. So lightning bugs aren't fast. But flying is important to their lifestyle and to their general well-being.

Additionally, fireflies need soil for laying anywhere from 500-1,000 eggs at a time. The eggs hatch in about four weeks. The resulting larvae spend the summer eating and the winter living in underground tunnels until the soil temperatures tell them that it's spring.

So fireflies have important requirements to be met in order for their lives to be happy and successful inside. They need space to fly around in. They need soil for egg laying and overwintering. They need shelters such as grassy plantsto hide in during the day. They need others of their kind to communicate and mate with. They need nght-time schedules. This is what they're used to, and how they're happy, in the wild.
