Frontinellina frutetorum

Clase: Arachnida
Orden: Araneae
Familia:Linyphiidae
Orden:Frontinellina
Especie:frutetorum

Linyphiidae es una familia muy grande de arañas que han sido poco estudiadas. Muchas son muy pequeñas, de 1 o 2 mm y abundan en la hojarasca o entre la vegetación de matorrales. Otras, un poco más grandes, son mejor conocidas. En algunas especies los machos y las hembras conviven en la misma red. Construyen su red en áreas boscosas, bajo matorrales o en pastizales altos, entre montones de piedras y sitios semejantes. Algunas de estas redes tienen aspectos caprichosos, en forma de domo o cúpula, o semejan un tazón sobre una servilleta individual, pero todas poseen algunos hilos pegajosos. La araña siempre se sitúa por debajo de la red, colgada, con el dorso hacia abajo. Cuando un insecto cae en sus hilos, la araña lo muerde por debajo de la red, lo jala a través de ella y lo envuelve firmemente con sus filamentos. Con este tipo de red, la araña queda bien protegida de sus depredadores.

English:
This is a very large family with more than 4289 species (June 2004) in 540 genera worldwide. In our region there are more than 300 species. Most of them are too small to recognize in the field
Most of the spiders of this family weave sheet like webs and the spider hangs under the web. Above the sheets the spider inserts scaffolding of threads. Insects fly against these strands and falls onto the web where they are caught. The spider bites throught the web to paralyze her prey. They are referred too as dwarf spiders. In the British Isles, they are called money spiders.
Nearly half of the spiders in Europe are member of this family. Their size is between 4 - 10 mm. Most of them have dark colors.
Members of this family occupy almost every spot on the world, from the Himalaya to beaches, from Antartica to the tropical forests.They reach these places because the spiders can fly by wire, called "ballooning". The spider raises her abdomen and releases a thread in the breeze that grows longer and longer until the upward lift is sufficient and the spider is lifted. They can reachs heights of up to 10000 meter and are transported to every spot on the world. They are often one of the first inhabitants of a devastated area like after the eruption of the Krakatoa in August 1883. In May 1884 scientist already reported microspopic spiders spinning their webs. Gossamer is connected with ballooning and the word comes from "goose summer". It is the moment that millions of spiders are taking off or landing.
