Menemerus semilimbatus
Salticidae (Jumping Spiders)
The Salticidae are small to medium in size and have a rectangular forehead. On the front of their heads, they have four large eyes that allow them to see better than spiders of other spider families. The retinas of the two eyes in the middle can move forwards and backwards in order to adjust the focus. Probably they are sensitive to polarized light as well as colours. The other four eyes do not have this ability and can only detect motion. All eight eyes together give the spider a nearly continuous 360° field of view, which in any case can detect movement. The Salticidae use their good eyesight mainly to hunt, whereby they approach their prey to a few centimeters and then jump and grab it with their often thickened front legs. They are very curious and sometimes almost completely raise their carapace to observe an object, such as a human or a camera. They show themselves mainly in warm and sunny weather. In gloomy weather conditions and during winter they hide in a silken retreat.
The different species can be distinguished from each other by differences in their markings and build. In Europe about 340 species occur. (arachnophoto.com)
