Note added 2001: I searched Totternhoe Knolls a few years ago without success – but please keep looking. There are plenty to be found on Dunstable Downs each year.
Because of the apparent dearth of sites in Bedfordshire, some in other nearby counties have been included. It is likely, however, that glow worms can be found on uncultivated hill slopes and waste ground elsewhere in the county. All suitable sites are worth checking.
