Are glow-worms at­tracted to ar­ti­fi­cial light?

BBC Wildlife Magazine - - Q&A -

Yes. Male glow-worms fa­mously take to the skies from May to Au­gust to seek out the glow­ing fe­males, and are eas­ily se­duced by ar­ti­fi­cial lights, par­tic­u­larly green ones (I once had 20 males swarm­ing around the green LED dis­play on my bat de­tec­tor). But or­ange and red ones are also ap­peal­ing – there are re­ports of in­di­vid­u­als flock­ing to red memo­rial can­dles, where they can be­come trapped and die. Sadly, amid our ever-bright­en­ing nightscape, female glow-worms are be­com­ing in­creas­ingly harder to pin­point. Laurie Jack­son
