It seems that glow-worms are in serious decline, probably due to habitat loss and pesticides, but maybe for other reasons. They prefer rough grass, and road verges were always a good place to see them. When some friends bought a house in France 20 years ago, our night walks would find thousands of them. Now it's down to just a few. Is it because the roadsides and ditches are now mercilessly mowed or are there other reasons?
We need many more people to survey them in Britain to try to establish some baseline data, so if you've nothing better to do on warm nights in July, resolve to get out and look for them next year, and report your results to your local Wildlife Trust.
