The characteristic green yellow glow produced by a firefly is the result of a chemical reaction that takes place in the insect's abdomen. This chemical reaction involves three ingredients luciferin (a heat resistant substrate and serves as the source of the light) luciferase (an enzyme that triggers the light producing chemical reaction) and oxygen (provides the fuel for the reaction to proceed).
Fireflies are out all day, you just get to see them better at night because of the light they emit.
Fireflies usually come out at night a little after sunset.
My Mom makes me come in the house at dusk.
Dusk is when lightning bugs make themselves most visible.Specifically, lightning bugs can be seen poised in the grass or on building and tree parts. But they do not light up until dusk. They may make themselves visible from early evening into 1-2 hours before dawn, from late spring into early fall, depending upon environment and weather.

Fireflies seem to be much more common in yards and grassy areas where lawn treatment and pesticides were never applied. Some experts say the firefly larvae is killed in spring lawn treatments. It could also be because they feed on snails and slugs which might also have been eradicated with pesticides and chemicals. I've noticed the evenings where I water just before dusk - my firefly count is quadrupled. I'm not sure if its the moisture that's bringing the fireflies or the promise of slugs in the damp areas. On evenings I don't water - I seldom see fireflies. Water the shadiest areas and the areas with most vegetation just before dusk and that will help attract fireflies.
Fireflies love warmth, so they come out during the summer months. You can start seeing fireflies in June, July and August, but they have a short life span.
Mainly at dusk they feed then so don't get in the water. but they mainly come out at dusk.
