Have you ever seen a glow worm?

Hodnet’s glow worms are locally famous, but have you ever seen them?
If not, and assuming you’d like to, would you know what you are looking for, or where?
Perhaps the simplest way to see them is to join a late evening trip being organised by members of the Hodnet Footpath Group, as per their notice below:

The number of glow worms spotted so far this year in both our
own and other areas has been unusually low, maybe due to the
cool start to the summer. However, some have now been sighted
and even though it's a bit later in the season than normal,
Hodnet Footpath Group members decided it was worth having a go.
We therefore plan to walk along the old railway track between
Hodnet and Wollerton on the evening of Friday 16th August,
meeting by the ex council yard (old auction yard) in Station
Road, Hodnet ready for a 9.30pm start.
We very much hope that you will be able to come along and join
us and that our efforts will be rewarded!
Just two precautions:
1. Please note - if it is raining, the event will be cancelled
without further notification.
2. Please read the safety notes below:
BE WARNED THAT THIS IS A WALK IN THE DARK OVER UNEVEN GROUND,
AND A TORCH, SENSIBLE CLOTHING AND STURDY FOOTWEAR ARE ESSENTIAL.
ANY CHILDREN MUST BE ACCOMPANIED BY AN ADULT.
PLEASE REMEMBER TO BRING ANY ESSENTIAL MEDICATION.
Hodnet Footpath Group can not accept any liability for loss of
or damage to property [inc clothing and personal effects]
Looking forward to seeing you on 16th,
Yours sincerely,
Mary Hardy
(Hodnet FPG Secretary)
