Question Re: fireflies

[The Minx]

I heard a couple of things about fireflies, namely

a) That only the males light up at night, and
b) That only the males fly.

Are either (or both) of these true?

Wikipedia is your friend: FireFly
The answer depends on the Species, it seems.

So there was an obvious solution to finding that out after all.

Seems that it's less common for females to fly or give off a light-show. But not impossible. Too bad it doesn't go into detail, but that's OK.

[Comrade Tortoise]

there are also predatory ones that mimic the return flashes of females to lure in males of other species... to eat them.

Now why doesn't this surprise me?

Nature can be so nasty. :)
