The first county record for
this species was made by Richard Lamb on 26 June 2010 at Marlcliff
the Avon. Three males were seen. Presence was confirmed a few days
later by Kay and Peter Reeve who visited the site and found two,
possibly three, males.
There is a known a vigorous population further down the Avon in
Worcestershire at Eckington and it was expected that in time the
would make the jump into Vice County 38.
In 2012 for the first time significant numbers of Scarce Chasers
were present on the Avon at Marlcliff. A visit on 25th
yielded fourteen males along about 400 metres of river bank and a
copulating pair. A number of the males were still showing their
immature colouration through the pruinescence. On a second visit
July 5th twenty-five were individuals were recorded at
Marlcliff and further upstream, close to Bidford on Avon, another
males were seen. The numbers and immaturity of a number of
is good evidence of local breeding. However, final proof will have
await the finding of exuvia and/or pre-flight emergents.
