does anyone know exactly what fireflies eat?

Many sources list slugs and snails as a food source for the larval form but whether adult fireflies even eat is unclear.

cool link, ive been curios about fireflys for some time now....

i'm working on making an environmentally friendly lamp any idea on how to catch them? since it seems like bait isn't going to work

Run around your back yard with a jar, as the sun sets.

i remember doing that...

yeah well i'm kinda lazy and the area where the fireflies swarm is quite soggy,muddy,humid,swampy. I'd rather just set up a jar-like trap

does anyone know exactly what fireflies eat?

Why fire of course!!

we get fireflys everywhere here. i can go to my yard or to the park and find a ton of them.

Fireflys? No it doesnt!!
