walking on water!

By CarolG  
I went in search of some dragonflies yesterday, but no luck. However, I did spot this raft spider skimming across the water.

Dolmedes is a genus of large spiders of the family Pisauridae. They are also known as fishing spiders, raft spiders, dock spiders or wharf spiders. Almost all Dolomedes species are semi-aquatic, Many species have a striking pale stripe down each side of the body. Dolomedes spiders are covered all over in short, velvety hairs which are unwettable (hydrophobic). This allows them to use surface tension to stand or run on the water, like pond skaters. They can also climb beneath the water, and then air becomes trapped in the body hairs and forms a thin film over the whole surface of the body and legs, giving them the appearance of fine polished silver.
They hunt by waiting at the edge of a pool or stream, then when they detect the ripples from prey, they run across the surface to subdue it using their foremost legs, which are tipped with small claws; like other spiders they then inject venom with their hollow jaws to kill and digest the prey. They mainly eat insects, but some larger species are able to catch small fish. They can also climb beneath the water, when they become encased in a silvery film of air.

I think these are the best Raft Spider images I have ever seen.
(They certainly are far, far better than any of mine taken at Combe Heath, Dorset SmileSmileSmile)

My ignorance of the insect world is matched only by my personal distaste of your subject today, Carol, but I have to admire both your knowledge and photographic skills: wonderful detail of this water skimming spider.......don't recall ever seeing an image such as this before.
Very well done.
