Damselfly Courtship
Male damselflies compete for females, grabbing them from the water. The
males try to keep hold of their female after mating,
but when she disappears underwater to lay her eggs, they can be dragged
under. Other males flutter around the pair as they submerge.

Dragonflies In Flight
The summer rains have softened the ground and from out of the peat bogs
emerge this year's dragonflies. There are more species here at Loch
Marie than anywhere else in Scotland, thriving on the abundance of rain
and midges, which makes this one of the best places in Britain to see
dragonflies.

Life of a Female Damselfly
A damselfly's adult life is so short that a newly hatched female must
mate and lay her eggs in the same day that she hatches. Her success
will depend on her fragile wings. Few insects can escape from a
spider's web, but her wings are more powerful than they look and the
female manages to pull free and avoid a sticky end. Over the stream,
dark-winged males compete with each other for the best territories. The
female watches and waits for a chance to mate with the victor. Once
mating is over, she must find the best location to lay her eggs. She
warms her muscles up, before taking off and flying low over the stream,
a dangerous strategy when there are insect-loving frogs lurking under
the surface. But she needs to lay her eggs underwater for them to
survive so has to dice with death. Then, for the first time, her wings
become a hindrance as they become waterlogged. But in fact they help
her in an unexpected way. She traps a bubble of air underneath them so
she's able to dive underwater, and stay under long enough to cut a hole
in a stem and lay her eggs. Then, she has to get out of the water fast
before she drowns, and once again her wings look like they'll spell her
death sentence. She has to use every bit of her strength to pull her
wet wings free of the surface tension and only the strongest of females
will survive this final test. |
Banded Demoiselles In Flight
The slow-moving water of a river is home to these insects, but to breed they move into the fast lane.

Living Fossils
Some fossils are almost identical to animals alive today - these are
known as living fossils. David Attenborough compares the fossilized
crocodile jaw to that of a living crocodile. A 150 million year old
dragonfly fossil has the same body plan as a modern dragonfly. And we
know what creature lived in a 50 million year old nautilus shell,
because pearly nautiluses still swim in the Pacific today. |
