The Museum
The Firefly can be donated to the museum. Upon doing so, the following text is given by Blathers:

"Both male and female fireflies are capable of producing light from their lower abdomens. This light isn't the same as the light from a lightbulb, though, and isn't hot when you touch it. Fireflies can actually glow when in the egg and larval stages, but that light is comparatively weaker."

Quote
Upon catching the insect, the player will say the following:

"I caught a firefly! Now I'm glowing with pride!"
