When looking for Dragonflies/Damselflies, it is best to go on a hot, sunny day.
A cool overcast day can be very disappointing.
The River Parrett and River Yeo around Langport and going up to Oath can be an interesting place to visit.
The White Legged Damselflies I photographed were all near the river Yeo, but I have seen them on the Parrett up around Oath as well.
I am planning to investigate this area a bit more, so I will update accordingly.
Late May / June

DAMSELFLIES: Banded Demoiselle, White-legged, Azure, Common Damselflies
NB The list above just names the key species during these dates and is not a complete list.
Route
There are various footpaths that go along both rivers. Just go for a nice stroll and see what you see.
The area I photographed the white-legged damselflies was just to the east of the abattoir, where Wagg Rhyne joins the River Yeo. Look in the fields behind as well.
Flat / Mixture of hard core tracks and grass tracks / Mainly Uneven.
