f = glowing females, m = males, l = larvae. Date of maximum numbers only is shown. Grid references are given only for publicly accessible sites. For more information about the UK Glow Worm Survey please go to www.glowworms.org.uk
I'm now adding a link to Streetmap.co.uk to the location for non-private sites. Bear in mind that glow worms are often spread over an area, so this may be the place to start looking.
