Most fireflies are habitat specialists, using woodlands, meadows and marshes. They rely on that habitat remaining undisturbed for the year or more it takes them to complete their lifecycles. If that habitat is disrupted during their youth, populations can be extinguished.
If a population of blue ghosts is destroyed by logging or other disruption, there will be no reestablishment. Habitat destruction is therefore one of the greatest threats to fireflies.
Other hazards include light pollution from artificial lights and perhaps insecticide applications for mosquito control. There is much yet to learn about fireflies. Entomologists like me have identified about or so species in North America , but it is clear that many more species occur here. Pay attention to the fireflies in your neighborhood; observe their flash patterns and behavior.

The area is wet most of the year and contains several shallow ponds. One summer was particularly bad with gypsy moths and the township decided to spray for the moth since many trees were decimated by the moth. The unfortunate byproduct to spraying for the gypsy moth was an end to the summer night spectacular brought on by the lighting bugs since their numbers were eliminated down to only a handful. Sometimes I think we should let nature run its course.

Bioluminescent beetles Fireflies produce light in special organs in their abdomens by combining a chemical called luciferin, enzymes called luciferases, oxygen and the fuel for cellular work, ATP.

And if they have a baby? Even the larvae and eggs emit light in certain species. One of the most fascinating ways to watch this process in action stems from Photinus carolinus fireflies, which synchronize their flashing patterns. Calling the Great Smoky Mountains National Park home near North Carolina and Tennessee, hundreds and even thousands of these synchronous fireflies emit between five to eight flashes of light all at once before allowing eight to 10 seconds of darkness.
This light pattern can continue for hours, usually ending around midnight. If you have fireflies around your home and you like the soft glow they create at night, keep this in mind, per Harrison: Be careful when you do lawn treatments.
