Product Information

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. 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!).

They were made of rubber, consisted of two parts, were worn on the upper arms, and inflated through a valve. They were first demonstrated in public on the beaches of Los Angeles, California, USA. [3] Female dragonflies can lay hundreds of eggs during their adult lives, in batches over a few days or even weeks.

In 1907, swimming became part of the school curriculum in England and caused parents to become more concerned with their children's safety in the water. In response to parents' worries, the Dean's Rag Book Company, London, introduced the Swimeesy Buoy, inflatable armbands with a colorful design that looked like the wings of a butterfly. A plain white version was also available. The product became so popular that it was available, almost unchanged, until the outbreak of World War II. 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. National safety standards such as BS EN 13138-3:2007 in the United Kingdom require inflatable armbands to conform to certain standards, like puncture resistance and the level of buoyancy retained after a period of time beyond the inflation valve being opened and left open. This is an assessment of the efficiency of non-return valves designed to prevent the armbands from deflating suddenly if an inflation valve comes open. Standards also require prominent labelling near the inflation valves stating that inflatable armbands are not life preservers and should only be used under competent supervision. Supervisors should be in the water within an arm's reach of the person wearing inflatable armbands. Damselfly larvae can be separated from Dragonfly larvae by their caudal lamellae, which are fin-like structures at the end of their abdomen that act as external gills. Dragonflies spend most of their lives as nymphs. Unlike typical larvae that moult only once, like butterflies, nymphs go through a more gradual change (metamorphosis) into adults.Mainly, adult dragonflies eat other flying insects, particularly midges and mosquitoes. They also will take butterflies, moths and smaller dragonflies. There is one Asian species which takes spiders from their webs! 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] Brilliant item. My daughter went from being very sceptical about the water to being able to swim with confidence and jump in the pool without fear. Doubt any other product would have made her feel so safe. Would highly recommend to anyone!' All dragonfly larvae have six legs (as do adults), wing-sheaths, an extendable hinged jaw (labium) that can shoot out in an instant and catch prey. Prey includes insect larvae, crustaceans, worms, snails, leeches, tadpoles and small fish. Dragonfly larvae themselves can fall victim to predators, including other dragonfly larvae, fish and waterfowl.

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.Woodland Trust (Enterprises) Limited, registered in England (No. 2296645), is a wholly owned subsidiary of the Woodland Trust.

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.
