Are glow-worms attracted to artificial light?
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
