Description Jumping spiders are my personal all time top favourite.These incredible creatures have such acute vision that they often look back straight at you !

I love to photograph them but find it rather challenging! This was taken at the new Romney wildlife centre in Kent.

Zebra spider
Salticus scenicus
Zebra spiders belong to the family Salticidae (also known as jumping spiders) who are believed to have the best eyesight of any arthropod. If you take a close look at one of these spiders it will often turn its head to look straight back at you.



Physical description
Female zebra spiders are 5-7mm long and males are 5-6mm. The most distinctive feature of these spiders is their two very large eyes. Although they have eight eyes, the two at the front are the largest and give them excellent binocular vision. These tiny spiders are black with white hairs that form stripes.



Distribution
Zebra spiders are widespread across Britain and are found throughout the world.



Habitat
They can be found on walls, plants and fences on sunny days.



Diet
Zebra spiders tend to hunt any insect or spider roughly the same size or smaller than itself. They have been observed feeding on mosquitoes, which are almost twice their length.



Behaviour
These spiders use their large front eyes to locate and stalk their prey. They move slowly towards their prey until they are close enough to pounce on top of their victim, and their hunting behaviour has been described as cat-like. Using their acute eyesight, they are able to accurately judge the distances they need to jump. Before jumping they glue a silk thread to the surface that they are jumping from so that if miss the target they can climb up the thread and try again. They ignore unappetising insects such as ants.



Reproduction
When these spiders meet, the male carries out a courtship dance involving waving his front legs and moving his abdomen up and down. The better the dance the more likely the female will want to mate, although arachnologists have yet to discover what it is the female looks for in a mating dance. Despite their good eyesight, males will sometimes accidentally perform a mating dance in front of another male. When this happens the two males usually fight. Males will also perform courtship dances in front of their own reflection in a mirror.

Females will stay with their egg sacs and will guard the young after they hatch. After the spiderlings have had their second moult they will leave the mother to fend for themselves.



Conservation status
Zebra spiders are not protected by law in the UK.

i know that spider's eye sight has long been a subject of great interest and investigation.Β  insects have been so long disregarded as just multitudinous pests that little concern or consideration to how they 'work' as in sight, hearing, feeling etc, little time was spent to determine how they lived from day to day or minute to minute
they have any number of eyes, depending on species i guess , or even among a single species. 8, ive read, and an odd number in others. you mention specific function of the larger or front eyes. and how they follow one. they follow the eye movements of the thing that set of eyes appears focused on, or who knows? maybe they have false eyes to confuse an enemy, too? One thing for sure is that spiders and many other "insects" are highly develop or evolved species and more adept at doing what they need to do to survive than other so called evolved species. and we dont even know what they use for a brain to accomplish all these feats.
here where i live, ive seen only a couple of jumping spiders. brownish and aggressive of all things. against humans and pets, ive seen them stand up to -literally rear up- and lunge at things hundreds or thousands times larger. i never got close enough to use any macro lenses though. and my photographic days ended a few years before the invention or advent of digital cameras . the Nikon d6000 dslr is affordable too. but i know no more about the needΒ  for higher quality optics or anything else in the digital slrs. i can say that there have been lots more excellent macro shots of things i never could hve managed in my mechanical slrs without lots of luck and miles of film.very impressive bunch of images you've posted here.

Hello, thank you for your input it is very welcome. I started photography using film slrs, I only had a 50mm lens to go with it and that's all I used at the time. I love digital as any adjustments can be seen immediately and I feel that learning on these systems are a lot quicker. πŸ‘πŸ˜ŽπŸ‘
