Keep Fireflies Glowing
in Your Backyard
There are several ways that you and your neighbors can help the fireflies
in your area:
Visit Marc Branham's "Firefly
Files" web site, and learn more about these tips from him:
- Have a Chemical Free Backyard
Reduce or, better yet, eliminate using chemicals in your yard.
- It's Like Using a Flashlight in Daylight
Limit or reduce extra light. A firefly's ability to see other fireflies'
flashes may be impaired if there is too much surrounding light. Think
about it, it would be like trying to see a flashlight in the daylight.
Also, it seems that some firefly species may not even flash at all if
there is too much light. As Marc explains it, "many firefly species
are active only during a certain period of the evening. These insects
determine when they will flash (i.e., the time of night) by the intensity
of ambient light. This is why you don't see many fireflies flashing
on clear nights when the moon is full."
- Plant or preserve low overhanging trees, tall grass
or similar vegetation in your yard, which will provide adult fireflies
a place to rest during the day and remain cool.
