Garden Centre Endemic.

 Periodically on here I mention some of my dabbles in Spider hunting. That's maybe too proactive. Mostly the spiders just leap out in front of me for attention so a photo is taken and I try to identify it. Some reckon that there are only about 10 species that can be done from images but whilst there are only a small percentage that can be identified in this way its certainly more than ten. Even with my amateurish attempts I have still managed about 50 on the list. Fair enough, they are 50 of the most distinctive species, but surely I've not mis-id'd 40 of them.

When they first caught my attention a couple of years back I bought the 'Wildguides' Spider book. A few pages were more memorable than others including this one - 


You can see in the observation tips, this unusually shaped arachnid 'appears to be restricted to Hothouses and Garden Centres'. Bizarre that some wildlife can be 'endemic' to Garden Centres I thought.

The Spider Recording Scheme website notes - Not formally included on the British checklist although recorded in England in the early 1990s in three widely separated localities - Liverpool, Southampton and Reading. The species is now extremely common in greenhouses in the Reading area and is increasingly being recorded further afield. The spider has been found in every garden centre searched in Cambridgeshire, Huntingdonshire, Bedfordshire, Suffolk, Hertfordshire and Kent and it has recently been found in a Leicester garden centre where it was fairly common within several of their heated glass houses .

With this in mind, it was a species to keep in my back pocket for those often banal visits to the local garden centre where I might find one in among the conservatory cane chairs and padded knee trays. The distribution map shows they have been found either side of us so there was an outside chance.

Then I promptly forgot about it. Until Sunday.

I took Peggy out for her last bedtime stroll around 11.30pm. When we came in I dried her feet and unclipped her harness in the porch. The ceiling is low in here, and I had been followed in by a moth so I scanned around for it possibly settled. There were a couple of resident small spiders ( Zygiella x-notata) around the windows but on the top was a faint web with something stuck in it. I couldn't make it out, but it was tiny and was maybe a bird seed husk blown in or a shed skin of one of the Zygiellas?I gently touched it. 

It moved. 

As I watched it illuminated by head torch its identity soon dawned on me. It was a Garden Centre Spider Uloborus plumipes!

Wow, well I never. The camera and flash were hurriedly sought and images taken. I cant be sure how a hothouse endemic came to live in our bitterly cold porch but suspect last week's visit to Stanton Nurseries for some garden plants might be the source.

 It seems that this could be the first for VC68 if not Northumberland so it has been iRecorded. Its amazing how we can travel all over looking for various rarities and a smart, unusual lifer is living at home with us...

The moth took a back seat but after the spider photo shoot was over, a nice Early Thorn was caught on the kitchen wall and released...

Not going out...

If Lee Mack was just loafing around his flat all day he could do worse than look for spiders! I was just locking up before bed late last night and saw a tiny spider walking over the kitchen chopping board. It was not much bigger than a money spider and it looked nothing much but I decided to have a closer look. I am pleased I did because he is a right beaut!

Meet Pachygnatha degeeri, a common spider that usually lives outside...

A spiders year....

Last Christmas I was given a copy of the new Wildguides book, 'Britains Spiders'. This inspired me to look out for some of these much maligned creatures on my travels.

If you are on Facebook you should check out UK Spiders page. On here are real experts from the UK and abroad who can help with some tricky identifications. On here this year some members have been doing a spider year list, with Graeme Lyons finding 360+ species so far! The vast majority of these can only be identified with a microscope and specialist keys to work out the correct result.
For a novice like me, I am happy to just photograph what i find then see if I can sort it out. If not I try the experts.

Anyway, here are some of the ones that have crossed my path this year...

1. Arctosa cinerea the Grey Wolf Spider.
 When looking through the book one species in particular caught my eye. The Grey Wolf Spider Arctosa cinerea. This is a species of restricted distribution and is found on riverine shingle habitats in Wales, Northern England and Scotland. It was this northern distribution that attracted me as we have loads of good habitat in Northumberland with no one looking. We visited a likely looking site in the Cheviots in June finding 7 individuals without much trouble really. In winter these shingle beds are flooded by several feet of water from the hills, but these mini tarantulas just hide in a burrow under a rock and let the water run across them. A top creature.

These little pea green spiders are common so I set about searching our garden and soon found this one. A gem of a spider...

Woodlouse Spider Dysdera crocata
The Woodlouse Spider lives around our sheds in the garden. It is an unusual looking spider being reddish with a body like a baked bean. As the name suggests those large jaws hunt and kill woodlice.

Ero furcata
I didnt expect to see this Ero on our shed. It has two pointed humps on its abdomen that are quite distinctive. It creeps around at night hunting other spiders.

Nursery Web Spider Pisaura miribilis
I just love these spiders. They are like 70s sport saloon, a Capri maybe in design and behaviour. With the yellow go-faster stripe down the thorax and its habit of running flat out to get away, its a top one to look out for. A common species but very few records for Northumberland. Ive had a few in the garden all year!

Goblin Spider Oonops species.
These tiny orange spiders can be one of two species both equally as common as the other. I found them in the bathroom, porch and moth trap. A tiny spider that moves in slow motion!

Four spotted Orb Weaver Araneus quadratus
Up here the Four spotted Orb Weaver is a species of the moors where it favours the strong bent stems of rushes for making its web. It is our heaviest spider and one I was pleased to find. About the size of a malteser.

I'll add some more soon.....
