Several species of dragonfly are known to collect in large aggregations or swarms. In Europe, the Migrant Hawker (Aeshna mixta) and the Four-spotted Chaser (Libellula quadrimaculata) have been observed to do this. In most cases this appears to be due to very favourable feeding conditions in the locality. It may also be a “courting” group with males actively searching for females. This is less likely as males are much more aggressive to each other when looking for a mate. In prehistoric times dragonflies were much larger, the largest flying insects ever. The largest member of the extinct Protodonata was the Permian Meganeuropsis permianawith a reconstructed wingspan (based on fragments, scaled to complete fossils of similar animals) of about 70-75 cm.

All dragonfly nymphs have six legs and wing-sheaths. They also have a hinged jaw that can shoot out in an instant to catch prey. Nymphs aren’t brightly coloured like adult dragonflies. Many are green or brown, so they are camouflaged from predators. Endophytic eggs are elongated in shape and are laid into plant material. All damselflies and hawker dragonflies have scythe-like ovipositors and inject their eggs into plant stems or leaves, rotten wood or mud on or close to the surface of the water. Emerald damselflies and Migrant Hawkers inject their eggs into rush stems well above the water surface, while other hawkers lay into rotten wood or other debris just above the waterline (see Brown Hawkers, right). The Golden-ringed Dragonfly lays its eggs by hovering vertically and stabbing its abdomen into stream-beds. Don’t worry - they don’t bite us. They’re completely harmless, and actually helpful for humans, as they hunt the pesky insects that bother us. Dragonflies undergo incomplete metamorphosis; unlike other winged insects, such as butterflies, dragonflies do not have a pupal stage and transition straight from a larva to an adult. This transition, the final larval moult, takes place out of water. This metamorphosis is triggered by day length and temperature, and is synchronised in some species, such as Emperor Dragonfly. A similar design of inflatable armbands for swimmers was invented by Bernhard Markwitz in Hamburg, Germany. In 1956, Markwitz's three-year-old daughter fell into a goldfish pond and nearly drowned. As a result, Markwitz invented and developed a swimming aid that would be safer for children than swimming rings, which at the time, were made of cork. A lottery win of 253,000 Deutsche Marks gave him a suitable start capital. In 1964, Markwitz developed the armbands in their final form and marketed them under the name "BEMA". Their modern name in German, Schwimmflügel, literally translates as "swimming wings".Water Wings is a year round swim school with indoor heated pools, that caters to the needs of children and adults of all ages and abilities. From beginner classes to advanced swimming lessons, Water Wings has a program for every student. An old name for damselflies was ‘Devil’s Darning Needles’. This stems from an old myth that if you went to sleep by a stream on a summer’s day, damselflies would use their long, thin bodies to sew your eyelids shut! Naturally there is no truth in either myth Female dragonflies can lay hundreds of eggs during their adult lives, in batches over a few days or even weeks. It provides fixed buoyancy and encourages a natural swimming position, helping young children get comfortable and confident using their arms and legs to move around in the water. I have found a dragonfly that has a damaged wing – will it still be able to fly – what can I do to help it?

Dragonflies spend most of their lives in their larval stage. During its time the dragonfly catches and eats live prey at every opportunity, moulting a further 5–14 times until it is fully-grown. Larval development typically takes one or two years, but ranges from 2–3 months (emerald damselflies) to more than five years (Golden-ringed Dragonfly). Development takes longer in cooler waters where food is scarcer, whilst in warm waters there may be a new generation every year. Tenerals are newly-emerged adult dragonflies that are weak in flight and pale in colouration. As the body and wings harden off they begin hunting for food whenever fine weather permits. They spend about a week feeding away from water and gradually acquire adult colouration and sexual maturity.I have a pond but cannot seem to get dragonflies and damselflies to live in it – is there anything I can do to encourage them to use it? The nymphs look like mini adults without wings. You’re unlikely to spot them as they live underwater. a b c d "Water Wings: One of the safest buoyancy aids for children learning to swim".

I have bought some pond plants for my aquarium and a dragonfly / damselfly has emerged and is flying around my house – what shall I do? There is a dragonfly that has been resting on my wall / hedge for a day, is it ill – what can I do to help it? The Zoggs Water Wings Vest gives your child unrivalled freedom of moment and helps them discover the joy of theunderwater world with confidence, learning how their body interacts with the water and how it is the water, not the vest that keeps them afloat. Your child will feel secured and completly free to move about how they want. Perfect for learning to swim (and having fun!). Once nymphs are fully grown, they crawl out of the water and shed one final time. They emerge as young dragonflies, then wait an hour or so until their wings harden and they can fly. Until their wings harden they are extremely vulnerable to predators. A tiny tadpole-like prolarva emerges from the egg. If the egg is laid above water, the prolarva wriggles to safety as soon as it hatches and moults within a few hours. Prolarvae that hatch below water moult almost immediately.Inflatable armbands, usually referred to as simply armbands, water wings, swimmies, or floaties, are swim aids designed to help a wearer float in water and learn to swim. [1] The larvae, which live in water, eat almost anything living that is smaller than themselves. The larger dragonfly larvae are known to catch and eat small fish or fry. Usually they eat bloodworms or other aquatic insect larvae.
