In Britain there are 300
species of Noctuid Moth, the largest is the 'Red Underwing' (above)
which has a wingspan of around 80mms. They are fairly common in the
south of England, but become scarce further north.
When resting during the day it is almost invisible, perfectly
camouflaged against the bark of a tree. When disturbed it flashes its
bright black and red petticoats in an effort to surprise any attacker,
such as a bird.
Latin name:Noctua pronuba
The Large Yellow Underwing Moth (left) employs similar 'disguise
and
surprise' tactics, although as its name suggests, the petticoats
are yellow. It
has a wingspan of around 60mms. During the daytime it rests at
ground level
amongst grass. The green caterpillars of this moth are known as
'cutworms'.
Latin name: Scoliopteryx libatrix
The Herald Moth (left), another noctuid, can be found in most parts of
Britain.
Unlike the Red Underwing, the Herald Moths' bright orange
forewings are
always on view, so in an effort to conceal itself from predators
during the
daytime it rests among dead leaves. It is one of the few noctuid
moths that
spends the winter in the moth stage, hibernating in buildings and
caves.
Moths are like the butterflies of the night, flying by moonlight in
search of nectar rich flowers to feed on. Just as butterflies have to
avoid capture by birds during the daytime, night flying moths have to
avoid capture by bats. Moths have sensitive ears, located just under
where the hind wings join the body. When they hear the ultrasonic squeak
of a bat, they close their wings, and drop like a stone out of harms
way.
Latin name: Phlogophora meticulosa
The colours of the Angle Shades moth (left) vary from green to red. The
larvae
can be green or brown and feed on low growing plants. At rest the
moth
resembles a wrinkled leaf. This
one has just emerged from its pupal case.
