instructions in the programme and telephoned
the leader prior to the event taking place were
able to join me during the course of the evening
when one of the lamps was run in the middle of
a white sheet on the ground. This method is
particularly useful in recording the more wary
species that often do not enter a trap proper.
In all, 93 species came to the sheet, and a
further 15 species were "new" when the traps were
examined in the morning. This makes a total
of 108 species, including "micros".
27 species of geometer included the large twin-
spotted carpet Xanthorhoe quadrifasiata and
haworths pug, Eupithecia haworthiata although
the hoped for cloaked carpet Euphyia
biangulata did not put in an appearance this
time. Amongst the larger moths, perhaps the
most interesting was the maple prominent,
Ptilodontella cucullina, normally found on
more chalky substrates. The Noctuidae numbered
28 fairly common species, of which the most
noteworthy were the aberrent form fraterna of
the bullrush wainscot, Nonagria typhae, and the
twin spotted wainscot, Archanara geminipuncta.
Interesting micros included the rather pretty
Argyresthia goedartella and the weird shaped
Ypsolopha dentella.
No great rarities, but a generally enjoyable
time was had by all, including the beginners
that were present, and I look forward to
another trip next year if Members are interested.
