When I was about six I made a lantern with Tennessee fireflies in a jar until a Ranger threatened me with jail for false imprisonment. Luckily no fireflies were harmed in the making of this memory as I set them free to avoid embarking on a criminal lifestyle. But I still love fireflies and made this design as a companion to the dragonfly I designed last year.
I used Sulky Holoshimmer thread for the firefly body and lettering. And I used Kreinik rainbow blending filament added to color for the wings, and Kreinik glow in the dark blending filament for the tail, for a glow around the tail, and just for fun in the flower centers.
