lighting lovers’ lane: welsh council switches street lamps to help glowworms’ sex lives - solar street light design

After environmentalists raised concerns about the adverse effects of lights on insect mating habits, the head of the committee decided to change the way Landenduno lights were used.
A local naturalist warned that street lamps pull male fireflies away from female ones because they are attracted by the strong light of sodium lamps.

With dynamic lighting, the firefly community in Landendono is thriving.
Amateur naturalist Jenny Cox found this problem on a local coastal trail.
"I first found them in 2011, when I was walking along Marine Drive.
I reported my findings to the National Firefly Survey and counted them back.
I counted 300 females, although few males seem to have found them, "she told the Daily Mail.
"Later, I found as many as 50 males gathered under the street lamp. I wondered if they had been prevented from finding females. So I reported this to Anne Butler, the biodiversity officer of the Commission.
Cox studied insects that lived for about two years by counting the number of males and females in the area every night during mating season.
She is particularly interested in their population and habits.
She counted 700 women and 800 men one night.
Female fireflies emit light through chemical reactions in the tail.
"I just hope that all the work I've done will help fireflies on a larger scale in the future.
I'm glad I helped them here, but if it could help me in a larger way, I would be very happy, "Cox said.
Annie Butler, a member of the local council, insisted that LED lights played a big role.
"A few years ago, Jenny drew attention to it," she said.
"We experimented several times with different street lamps, and we got good cooperation from the street lamp team.
