this plan:
1. Location of rare butter-Fly colonies in
Essex
Details of any known colonies (or locations
where the species has been sighted since 1980)
are needed for the butterflies listed below.
You are urged to give as much detail as pos-
sible, including the exact location, so that
the site can be re—surveyed to see if the
species survive. Information will be treated
in confidence and only revealed to those people
doing the survey work and to those organis-
ations that can help conserve the site. The
risks of species loss by habitat loss is much
greater than the risks from collectors — so
please don't be secretive about these important
colonies.
Species where we are attempting to locate all
known colonies:-
Dingy Skipper
Grizzled Skipper
Brown Hairstreak
Green Hairstreak
Brown Argus
Silver-Studded Blue (probably extinct)
White Admiral
Purple Emperor (probably extinct)
All Fritillaries (probably all extinct except
Heath and Pearl-bordered on nature reserves
where they have been re-introduced)
Marbled White
Grayling
