These are my favourite spiders.
When you have attracted their attention, they follow you with their big
eyes. They are friendly little creatures that always like to jump on your
camera or your fingers. |

Ligonipes semitectus, ant mimicking spider from Australia |
Some species exhibit an amazing resemblance with ants and are called "ant like " spiders. They belong to the genus Myrmarachne. The one shown on the left was found in Australia. Because of its resemblance to ants, it can walk between them without being attacked. Salticids can be found everywhere if the sun is
shining, on trees, grass and rocks. At night or during rainfall the spiders
hide in a dry spot under a small web.
|
Prey can be noticed from a distance of about 30 - 40 cm. At a distance of 20 cm the spider turns its body so that the two front eyes points to the insect. The muscles in the eye focus the eye on the prey and the eye moves around their optical axis. In this way the spiders scans the object like a modern scanner. The effect is extraordinary. The eyesight is enhanced like a zoom lens and it is capable to adjust its looking angle from 10 to 60 degrees. In experiments it was shown that the spider is capable to distinct dangerous insects and prey. The eyes are also capable to see colour. After the object is recognized as eatable the spider carefully moves towards it victim As you can see the on the picture they also catch prey, much bigger than themselves. It was spectacular to see the little Salticus scenicus catching the big fly. Salticids are the tigers among spiders. The
spider slowly advances towards its prey. When it is at a reachable distance,
it jumps on its prey and grabs it with its jaws. They use their third and/or
fourth pair of legs for jumping. If you notice the spider on a wall, often
the Salticus scenicus,
it seems as mocks at gravity. It jumps of the walls and falls back on it
several centimeters further instead of falling down. This is because of its
lifeline. If you watch the spider carefully, you can notice that it always
releases a lifeline when it jumps. If the jump fails it can crawl back to
its original position and it prevents the spider from falling down.
For the American continent there is a large site dedicated to jumping spiders: Jumping spiders in America |

Dendryphantes.
Its size varies between 4 - 6 mm and she can be found

stones or on vegetation and are guarded by the female.

Only one species occurs in NW-Europe. The size of
the fast moving spider is 5 - 6 mm and Myrmarachne can be found amongst stones
and low vegetation.
The body is brown and black. The male has remarkable

Spiders in this genus resembles and mimic the
behaviour of ants by waving their front legs to mimic antennae.
They live together with ants and are probably
protected because they wander between the ants and therefore avoid being eaten
by predators.
