Grayling, Speckled Wood and Silver-studded Blue butterflies.—It may
be of interest to put on record that these three species were taken in the
neighbourhood of Kelvedon, near Brentwood around the beginning of this
century. I have personally seen the specimens and the owner vouches for
the exact localities.
None of these species has been seen there of recent years but I took a single
specimen of the Silver-studded Blue (Plebejus argus L.) near Fryerning two
years ago and a friend took and released a Grayling (Eumensis semele L.)
in the same area last August. It would seem that there are still some isolated
and restricted localities for these two species in the High Woods area, but I
know of no recent record for the Speckled Wood (Pararge aegeria L.)
