Interesting facts about the Zitterspinne
- The Zitterspinnen or Pholcidae describe a very species-rich family within the real Webspinnen, which occur all over the world and colonize different habitats.
- They are as prevalent in tropical and subtropical forests as they are in rocky landscapes and human dwellings in temperate zones.
- In Central Europe are mainly species native to the Mediterranean and immigrated.
- The most well-known representative of the Central European Zitterspinnen is the large Zitterspinne, which is to be found in many houses. It is considered beneficial, because it eats annoying pests and at the same time is considered safe.
- Due to its stature, it is often confused with the weaver, but can be easily distinguished from it by its divided body.
- Like the Weberknecht, the Great Zitterspinne has very thin legs, which can be up to five centimeters long.
- The body is at most one centimeter tall, of whitish gray color and in places almost transparent.
- The males are easy to recognize because of their pronounced genital organs at the head.
- The jigging spider owes its name to its ability to swing its web back and forth in case of threat. As a result, their outlines become invisible to the attacker and this leaves off from his potential loot.
- In quiet corners and angles, the Zitterspinne builds its large-scale three-dimensional network, which, in contrast to other weaving spiders, looks rather structureless and consists of innumerable threads interwoven with each other without any visible arrangement.
- As dandruff spiders move very fast and with little movement, they manage to easily overwhelm their prey, which is much larger or more compact than themselves.
- Also, the high elasticity of the threads contributes significantly to the success of prey, as caught insects can hardly free.
- After mating, the female zander spiders spin wafer-thin coco, into which they lay about twenty eggs. The cocoons also carry the females with them when the young spiders have already hatched, but remain in the care of the mother for protection.
- The Zitterspinne can reach a life of over three years.
