This is Aculepeira ceropegia known in English as Oak Spider. Becouse there isn't ,any info about this specie on internet, some facts about oak ;-)

The Pedunculate Oak or English Oak (Quercus robur) is native to most of Europe, and to Asia Minor to the Caucasus, and also to parts of North Africa.

It is the type species of the genus (the species by which the oak genus Quercus is defined), and a member of the white oak section Quercus subgenus Quercus section Quercus. The populations in Italy, southeast Europe, and Asia Minor & the Caucasus are sometimes treated as separate species, Q. brutia Tenore, Q. pedunculiflora K. Koch and Q. haas Kotschy respectively.
It is a large deciduous tree 2535 m tall (exceptionally to 40 m), with lobed and nearly sessile (very short-stalked) leaves 714 cm long. Flowering takes place in mid spring, and their fruit, called acorns, ripen by autumn of the same year. The acorns are 22.5 cm long, pedunculate (having a peduncle or acorn-stalk, 37 cm long) with one to four acorns on each peduncle.

It forms a long-lived tree, with a large widespreading head of rugged branches. While it may naturally live to an age of a few centuries, many of the oldest trees are pollarded or coppiced, both pruning techniques that extend the tree's potential lifespan, if not its health. A specimen of notable longevity is one in Stelmuė, Lithuania which is believed to be approximately 1,500 years old, possibly making it the oldest Oak in Europe; another specimens, estimated to be about 1,200 years old, grows in Denmark.

A close relative is the Sessile oak (Quercus petraea), which shares much of its range. Pedunculate Oak is distinguished from this species by its leaves having only a very short stalk 38 mm long, and by its pendunculate acorns. The two often hybridise in the wild, the hybrid being known as Quercus x rosacea.

Within its native range it is valued for its importance to insects and other wildlife. Numerous insects live on the leaves, buds, and in the acorns. The acorns form a valuable food resource for several small mammals and some birds, notably Eurasian Jays Garrulus glandarius.

It is planted for forestry, and produces a long-lasting and durable heartwood, much in demand for interior and furniture work.

A number of cultivars are grown in arboreta and in parks and gardens. The most common cultivated form probably is the cultivar Quercus robur 'Fastigiata', with a narrow and columnar crown. This is propagated from an upright tree that was found in central Europe. Several hybrids with other white oak species have also been produced in cultivation, including Turner's oak Q. x turnerii (Q. ilex x Q. robur), Heritage oak Q. x macdanielli (Q. macrocarpa x Q. robur) and Two worlds oak Q. x bimundorum (Q. alba x Q. robur), the latter two developed by nurseries in the United States.

Hi, Greg. It has been a long time since we dont post at the same time :)
The detail you obtain in this spiders is stunning. This time I would have prefered a perpendicular angle to get the most into DOF. Very nice colours and composition. Well done my friend. TFS.

I have never, ever seen a spider like this before, beautiful markings. Too bad we can't see the head!
Still, it is a stunning pic with a good DOF and lighting. TFS!

Hi Greg. These markings are both unusual and beautiful. I can understand why you used this POV as it makes the most of these wonderful markings. Great detail and lovely composition. TFS :)

Very good picture, Greg.
The details of the spider is very good, well composed and nice colours. The DOF is little shallow.
Very well done.

Hello Greg, interesting POV, I like it! Did you know that the white patterns are in fact not on the surface but are a result of a transparent cuticle that houses cells that store gaunine...there is always something to write about them :-)

Great shot. England saw this species in 1853 but not since then!

Nice one, a spider for all the spider fans! And they don't live in NZ! You even had me looking up on Google about the Aculepeira ceropegia and I agree, it does look like it!!

The head is that on the right isn't it? Well, the head and the body and front legs are nice and sharp. Good details. I'm quite happy with the softer back legs, because I think the emphasis is the body and front area. So well done, Good job!

Hi Greg,

Excellent shot. I have never seen one of there spiders. Superb color and detail. Just altiile falloff in the DOF. I like the way it is framed.

Grzegorz, maybe something like f/8 would have been better here, but this is a very nice shot.

I like colors, pov and composition; the blurred bg highlights the beautiful spider.

I can barely look at spiders without getting goosebumps! This one is interesting, I like the diagonal angle and the sharp clear markings on his body and legs. Well done.

Strange 'thing'. The symmetrical position of the spider works OK. I am however a little in doubt about the lighter areas of the background in upper right corner.
