Argiope bruennichi, Wasp spider
"The Wasp spider is a member of the orb-web spider family,
 and whilst it can be found across much of Europe and North Africa, it’s
 only in the last decade that it's appeared in the UK. These photos show
 a female, which is much larger and more colourful than the male. In 
fact, they can be disconcertingly large, compared to most indigenous 
species; the largest of the three individuals I found was about 8cm with
 its legs outstretched (this feels MUCH larger when it’s only a few 
inches from your face!) They do bite, but they’re not poisonous to 
humans.
 
 "Being so large and colourful, they’re easily spotted, and quite a spectacular find when out walking. The females are now, and a few of them have large egg sacks – and I do mean large; the largest of the two I’ve seen locally was just under 4cm in diameter, and was being tended by a slightly smaller female.
‘zig-zag’ section running vertically through them. No one knows quite what this is for, but there are several theories. It may be that it helps attract insects by reflecting UV light. It may also act as a deterrent to ward off predators; when the web is shaken, the zig-zag creates a bright, blurry shape to animals which see in the UV range."
A sea of webs ...
"These webs on the tips of grasses and bushes are mostly Garden spider 
webs. The name isn’t too helpful here, as Garden spiders aren’t just 
garden dwellers, and pretty much live everywhere. They also fall into 
the orb-web family, which also contains our largest by weight native 
species, Araneus quadrata, which, along with the similar but slightly 
smaller Araneus diadematus, are the ‘classic’ garden spiders, and – as 
you can see from the photos – they’re doing very well this year! On a 
dewy morning, you can see literally thousands of these webs, and they 
really are a spectacular sight … just make sure you keep to the paths, 
though!"
