Water Wings Swim School has been a member since 1988 of the United States Swim School Association. This trade organization is for operators of swim schools. The Water Wings Swim school believes having fun is the best way to learn how to swim. A child who enjoys swimming will be more willing to learn how to do it safely. In October 1931, a design for water wings appeared in the magazine Modern Mechanix. 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]

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. 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.I have found a dragonfly that has a damaged wing – will it still be able to fly – what can I do to help it?

Having the kids in the pool for the first time could be a little daunting, but learning to swim is one of the joys of childhood. Make it more enjoyable for them by providing some simple swimming aids which will help them feel even more comfortable in the water with some must-have swimming accessories. Swimming Float 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. The Woodland Trust is a charity registered in England and Wales (No. 294344) and in Scotland (No. SC038885). A non-profit-making company limited by guarantee. Registered in England No. 1982873. 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.Where to see: most often found near bodies of water or resting on tops of plants in woodland rides. The final-stage larvae sit in shallow water, near the margins, for several days, getting ready for their final moult and starting to breathe air. Most species leave the water during the morning, but hawkers do so under cover of darkness. Larvae climb up emergent vegetation, although some may walk several metres over dry land before finding somewhere suitable to emerge. After finding a secure support, they redistribute their body fluids, pushing the thorax, head, legs and wings out of the larval skin. There is then a pause of about 30 minutes to allow their legs to harden enough for the next stage, when the abdomen is withdrawn. The wings, and then the abdomen, are expanded and start to harden. This process leaves behind a cast skin, called an exuvia, and the whole process lasts between one hour (Damselflies) to three hours (Dragonflies). 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. 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.
