Both Open Day and our stand were a great
success.

Other successful Club Exhibitions were put
on at Ingatestone, Dagenham and Writtle Village
Shows, and we would like to extend a welcome to
all new members who joined the Club at the shows.
We should also like to express our thanks
to the staff of the Chelmsford and Essex Museum
for the loan of the stuffed animals and for
their able assistance and advice.

MORE ON BUTTERFLIES AND MOTHS ...
Many moths and butterflies have brilliant
eye spots that because of their superficial
resemblance to the staring eyes of birds of
prey cause them to be avoided by smaller birds.
Many such insects also flash their eyespots at
potential attackers by opening and closing
their wings. But this is not all. Bertel
Mohl and Lee Miller suggest that this wing
beating is also an anti-bat device. A rigid
section of cuticle at the base of the wing
produces an ultrasonic click as the wing is
raised, this "jams" or confuses the bats'
radar. Such butterflies and moths are thus
proof against both birds and bats. (J.Exp.
Biol. Vol 64 p 639)

One pair of scissors were left behind at either
the Dagenham or the Ingatestone Show - please
claim them from Ron Allen.
Still plenty of free test tubes left. Please
feel free to ask for as many as you wish - I
have thousands to give away.
