Another migrant returns - Brook Lamprey

This morning got off to a another cold and misty start but I added the Beautiful Plume moth (Amblyptilia acanthadactyla) to the year list from the garden trap. 
Driving round to Beeley Triangle I was surprised by a party of Whooper Swans crossing low over Screetham Lane towards Flash Lane but soon lost them in the mist. I think they were seen earlier over Ogston where they counted the group as 27 birds.
Last year during April Ken Smith located a small group of Brook Lamprey at Darley Bridge. They remained for most of the month constructing a communal nest and eventually numbered over 30 individuals. We had high hopes that this would be a regular Spring occurrence and today I hope that has proved to be the case with two Brook Lamprey busy in nest construction again at Darley Bridge. 
The water is not quite clear and is still fairly deep so photo opportunities will hopefully improve.
