It seems a tad silly to start a whole new thread for one image, but meh! This is a Theridion grallator or "Happy face" spider...



Bloody forbidden 403 poops! Apparently you can't access that image unless you type the URL into the address bar of your browser, so here's another two, just in case.

Mouth open...

and mouth shut!

Sorry to be a pain, but I'd be really grateful if anyone could tell me how to identify this spider or, even better, identify it for me!
I found it on a speaker last year on my canal boat on holiday.
It just struck me as odd because I've never seen one before and nor had anyone else on the boat. I've searched the internet to no avail, and it doesn't appear to be in any books I own.
Has anyone else seen a spider like this? It lays its legs down either side of its body, in a straight line.

(Sorry about the link, I'm not sure how to get it to be the right size to post in a post!)

The picture isn't a great one, could you give us a descrition, colour, size, and distinguishing marks or anything else not usually seen on an arachnid. It is fully possible that it is a hybrid or a species unknown to science ( of which there is still a lot).

Actually having looked at it again it looks like it may be a juvenile daddy long legs but I'm not an arachnologist

As I recall it would have been about 6-7cm across, including the legs. As you can see, the body was quite small and flat, and it looks slightly ridged as opposed to smooth. There weren't any very striking markings, possibly there were two slightly darker brown lines going down the back of the spider. The legs also had slight darker parts where they segmented.
The overall colour of the spider was a light brown with occasional darker bits.
The legs were very thin, and not all the same length. I'm not sure if this was due to damage, but the legs seemed to match up with their pair in length; the frontmost pair and the third pair look to be about the same length, while the second and fourth pairs were longer by perhaps about 2cm.
It also had quite long (Palps? Pedipalps?) for its body, (I think?) maybe about 1cm in length.
I'm not sure what the thing on its back is, it looked like a little battery or something. It was a tiny caramel coloured bar, with two black ends which looked like eyes. I didn't see where its eyes were, but I know they're usually at the front, rather than on its back!
I hope this is of a bit more help! I'm grateful for any more comments.

Having just looked for images, you may be right!
Hmm, that's not very exciting, is it?
Thankyou for your help! It was quite interesting at the time anyway, a novelty spider.

I'd still try and find an expert to check it out, the marking, which may be eyes on the back seems highly unusual and you'd think would make identification easy but I can't find anything

Yes, a lot of websites I've visited say that even if a spider looks the same as another, you'd need an expert to confirm it! Seems a bit strange, I mean how much can they vary exactly? Do spiders vary a lot even if they are exactly the same type?
Well, this is a daddy long legs and has some sort of strange thing on it, similar to my photo. This picture makes it look further forward though.

It's hard to search for good spider identification information on the 'web'. Hah, pun. Sorry.

Ooh, I've just found this!
Quote:
Order Opiliones: Daddy Long Legs or harvestmen are often erroneously designated as spiders; they are not. About 1900 species of harvestmen are distributed over the world in forests, fields and other land habitats. They can and do walk on water. We have 60 or more species in North America and the adults of all but one of these die with the coming of winter. They mate in late summer and autumn. The seven-jointed legs are unique - if we had legs in proportion, they would be 40 feet long. The small turret on the top of the head has a tiny eye on either side, capable of detecting motion from several feet away. These oddball creatures are some of the most abundant on our forest floor, and they climb about all over hell in low foliage.

It was here, down the page about two thirds.
So, they are eyes of a sort!

A spider has just been named after Neil Young. The spider, called Myrmekiaphila neilyoungi, was found in Jefferson County, Alabama, in 2007.

There's also a spider named Bagheera kiplingi, named after the panther Bagheera in Kipling's Jungle Book. Apart from that rather cute name, it sports a very unusual feeding habit for spiders: It is mostly herbivorous, meaning it eats plants! It steals protein-rich capsules of an acacia from ants living on the plant that also eat these capsules.

I haven't had a large spider in the house for several months, until Sunday that is. In the space of 3 hours I had no less than 3 huge house spiders. Then, speaking to a relative today, they started by telling me that they had killed two big spiders on the same night!
Now I know it is the breeding season for spiders in the UK, and that brings out the larger males. However, how did they all knwo to come out on the same day? Was it a huge (hairy :) ) conincidence? What triggers them to search for a mate? The weather?

I suppose it's similar to the way all the ants seem to know it's time to all come out and go flying on the same day...though yeah, I'm not really sure how they know, either ;).
