Ours are gone! Never had seen them before those two-three nights and have not seen them since. Of course I am not sitting outside in the light now either so maybe they are there...waiting for a target.
I don't know if there is a "regulation" flash light tag
but we were at someone's house when our children were small and this is what they did. Each child gets a flash light after dark and then they run and hide, usually around the perimeters of the house or behind bushes, or trees etc., and the person that is "it" has to find them and shine their light on them, (tag) at that point the tagged person is "it" as in a regular game of tag, and the others flee. This usually illicits lots of laughter and shrieks and is a fun activity for little ones. Or you can play it, catch one catch all, and then once you are tagged you join the tag team and the team goes after the others together until the last one is found. When the seekers can not find the hiders the hiders will either call out or flash their light for attention.
But my, I like the bug on a string flying idea, I just don't want to be the one to tie it on!!!
No lightning bugs here yet usually around the 4th of July they make their display here. I liked to catch them too but sometimes I used to step on them to see the glow stay lit.
