Wasp spiders in Britain
September 20th, 2009 | by Nick |
Wasp spiders ( Argiope bruennichi) are originally from Continental Europe andeprobably arrived in Britain from a Channel port in the 1920s. Since then they have been gradually spreading their domain across the south of England, reaching Cornwall and encircling London. The amorous practices of these spiders are interesting. The male waits on the threshold of the female’s web until she has shed her skin to become mature. He then takes advantage of the fact that the female’s jaws are soft to mate with her in safety. Many males, however, in their impatience misjudge things and are eaten while engaged in the act. Note, despite its threatening colouration this is not a dangerous species. The wasp-like appearance is probably to deter predators. In the very unlikely event of a bite the effects are likely to be mild swelling and itching at the site of the bite.

The oldest osprey of the UK – and probably the world – has returned to her eyrie in the Scottish highlands. When she left for West Africa at the end of last summer, no one expected her to return. At 26 she’s lived 3 times longer than most female ospreys. In her life she’s laid 58 eggs and hatched 48 chicks, a massive individual contribution to the survival of ospreys in Scotland, where there are still only about 200 breeding pairs. The questions now are if her mate will return and if she is still fertile. Events can be followed on the 
Otters, water voles and fish are all benefitting from the improved quality of the UK’s waterways, now described as the cleanest since the industrial revolution. Since almost disappearing from the wild in the 1970s, otters are thriving, particularly in the south west of England, Cumbria and Northumberland. The population of water voles, highly precarious in the 1990s, is also beginning to recover. The good results of stricter pollution controls and extensive conservation work are set to continue in the new year with the introduction of new European water quality directives.
