Fen Raft Spiders
 
Carlton Marshes is one of the few places in the country which supports breeding colonies of Fen Raft Spiders. Despite being about 7 cm in diameter, these semi-aquatic spiders are extremely difficult to spot amongst the vegetation and I have searched for them without success every time I have visited recently. However, today I 'got my eye in' and managed to find four of them. The two pictured here are females with their egg sacks which they keep cool by submerging them in the water.

Note: Two new photos have been added towards the end of the thread.

E-M1 II and 300mm F4.

I am not generally a great fan of spiders myself Janet but I was very keen to find some of these monsters. I am glad they spend most of their time on water though, rather than lurking in a corner of my bedroom. :)

Never heard of a spider that dwells on water. I Googled it.

is a European species of spider in the Pisauridae family. Like other Dolomedes spiders, it is semi-aquatic, hunting its prey on the surface of water. Wikipedia
Conservation status: Vulnerable Encyclopedia of Life
Scientific name: Dolomedes plantarius
Did you know: Only three populations of the Fen raft spider are known in the UK: Redgrave and Lopham Fen in Suffolk, the Pevensey levels in East Sussex, and Pant-y-Sais Fen and Crymlyn Bog near Swansea. buglife.org.uk.

Interesting.

Nice Ron I would like to see those myself.
The second shot is the best as you see her eyes a portrait crop could improve it

Many thanks for the comments. I liked Alf's suggestion of a portrait crop for the second shot, so I have replaced it with a cropped version. I think it looks better.

Yeah, but it's not like a real spider, is it Mark - funnel web, redback etc.?

Nice captures Ron, well done.

I've visited Carlton Marshes a few times however, I've yet to spot one of these.

ARACHNOPHOBES LOOK AWAY NOW.

I was at Carlton Marshes today so I went to look for the spiders again. I found one or two, including this female with the pale orange 'go faster stripes' on the sides of her body.





The second shot shows one of several nursery webs, packed full with tiny Fen Raft spiderlings. I wonder how many of them will reach adulthood? This web was between 2 and 3 metres away, so unfortunately there is not a great deal of detail.
