Looooong legs!

 This Dicranopalpus ramosus harvestman posed in the flattened, all legs stretched posture typical of the species. There were lots of them sitting on headstones in my local cemetery today. When disturbed, they walk as a 'normal' harvestman', but soon after sit and stretch their legs again.

Daddy long legs spiders

I like having spiders at home - yes, I know, it is a bit weird and they might scare the visits. A couple of years ago we had an enormous garden spider (Araneus diadematus) in our kitchen, next to the back garden door and it eventually attracted a male. We watched the whole courtship over breakfast - live - it was fascinating. The male was extremely careful and moved slowly. A few times there was contact between the pair's legs. Unfortunately the poor male must have taken the wrong step, as the female grabbed him, and unceremoniously rolled him in a broad band of silk band and ate him. From then on we called her 'The Cannibal' and released her outside a little afterwards for her to lay eggs. I am not sure that male managed to mate before being eaten. Living on a restricted diet indoors, the female probably saw him more like food than like mate. Anyway, don't let me get distracted, I was going to talk about Daddy long legs spiders, Pholcus phalangioides, to be precise, who had lately fascinated me. If you have an outside toilet or a room next to a garden, have a look at the corners of the ceiling. You can maybe see thin 'upside down' spiders with spindly legs.
These are the spiders I am talking about. They look a bit like harvestmen, but the fact that they hang from a web tells them easily apart. Well, the spiders have lived with us for a few years, the occasional one being swallowed by the hoover. The other day I noticed one with a large prey wrapped in silk. When the spider discarded the remains I had a look and it seemed to contain a large spider, most likely a Tegenaria. Now is the time of the year when male Tegenaria move around the house - often falling into baths - and maybe it is now when they are more likely to fall prey of patient Pholcus. This is another spider capture I photographed:
Then a few days later I noticed that a Pholcus living in the outside toilet had a sac of eggs. I pulled the camera out to take some photos and, after looking at them realised that the female carries the eggs in her mouth, but they are not wrapped in a cocoon like other spiders but are visible, probably held together with a little silk. Apparently the females live for several years and can protect the eggs themselves - and possibly the spiderlings - also, because the females move to a different spot every few days, it makes sense to carry the egg sac with her.


Of course, this makes the process of spiderling hatching from their eggs visible - and relatively easy to photograph - too, and there is when I found this incredible set of photos of Pholcus spiders being born at bugguide.netAnother very informative website with good photos:
