Last night Bob and I went for a soak in the outdoor spa. It was a gorgeous evening. As is our custom after we soak for awhile we put on our robes and sit on our lawn chairs to dry off and cool down. It’s very dark where we live with no residual light from cities and towns. Last night we were treated with many fireflies. It’s been awhile since I have seen them and they were so beautiful. We must have has about a dozen of them flitting about and we were both going “wow”. What a treat.
I didn’t know that they are disappearing. I got this information from http://www.firefly.org/why-are-fireflies-disappearing.html. In addition to the loss of habitat as we continue to cut down trees, pesticides, and too many humans in their habitat, scientists also figure that there may be another reason which I thought was really interesting.
Too Much Light At Night
Scientists don’t know enough about fireflies to tell for sure. But the signs are indicating light pollution as a major factor in the disappearance of fireflies all over the world.
Both male and female fireflies use their flashing lights to communicate. Some species synchronize their flashes, sometimes across large groups of thousands of insects. All species speak a language of light—scientists believe they use it to attract mates, defend their territory, and warn off predators.
Human light pollution is believed to interrupt firefly flash patterns. Scientists have observed that synchronous fireflies get out of synch for a few minutes after a car’s headlights pass. Light from homes, cars, stores, and streetlights may all make it difficult for fireflies to signal each other during mating—meaning fewer firefly larvae are born next season.
Where fireflies once had uninterrupted forests and fields to live and mate, homes with landscaped lawns and lots of exterior lights are taking over. The reduction of habitat and the increase in lighting at night may all be contributing to make fireflies more rare.
Fireflies are fascinating creatures that light up our nights and bring a sense of magic and mystery to our environment. If they disappear, it will be a great loss to habitats and generations of people all over the world.
I hope you soon get to see the magic of fireflies at your home or in a park near you.
