Glow worm reports 2024

Most recent first.

F = glowing females by night, M = males, L = larvae.  NR = nature reserve; CP = country park. Only peak numbers during a season are shown, so not every record received is listed. Links are given only for publicly accessible sites, although we do not check that all sites are on full public access. Please note that the arrows on the linked maps may only be accurate to within 100-200 metres, so do not go on to private land or a garden on the basis of the arrow alone.  County names are those traditionally used for biological recording. Information is supplied on the basis of reports received and we can't guarantee that you will see any!

Thanks to Helen Welch for compiling the listing.
