The Pearl-bordered Fritillary has been extinct in
Nottinghamshire since the early 1980's, being recorded for the last time
in the county from Cotgrave Forest in 1981. There is an earlier Cotgrave Forest
record from 1978 (Radford, J.T.), but as there appears to
be no other county records listed anywhere between 1934
and 1978, it is impossible to say whether it was present
at Cotgrave Forest during those intervening years, or
they were the result of an attempted introduction of
captive-bred stock.
Carr
listed a number of historical records in his book
'The Invertebrate Fauna of Nottinghamshire. Nottingham: J.& H. Bell Ltd
(1916)' which suggests that the Pearl-bordered
Fritillary was never a common and widespread butterfly in
Nottinghamshire, rather it was restricted to woodlands
lying on generally dry, sandy soils north of Newark, near
Ravenshead and in the Clumber and Sherwood Forest areas. |
