Hello.
Yes they are big , they are Pulex.
There is a basin in the wood where there is a very heavy accumulation of Maple leaves.
As you can see in the pictures the water is very very dark very red and it's full of Daphnia, the water is so dark that even during the day you can't see the Daphnia, to see them I have to use the spot.
