Description of adults: Examined: 5 and 3 Body length: about 3 mm, about 6 mm (Nentwig at all, 2003) There is no significant difference in male and female colorization, only in body size. Both sexes are pale brown or yellow with characteristic dorsal mark on the abdomen. Legs are pale brown, spiny and ringed. Prosoma is also pale brown or yellow with black belt and middle line. Abdomen is white – yellow, with little greenish region, with 3 black spots and specific black pattern that looks like trident.

Distribution:

According to Platnick (2010) species has Palaearctic distribution, but there are some interesting white spots in Europe distribution. This common species is not recorded in Iceland, Finland, Albania and Bosnia and Herzegovina. (van Helsdingen, 2010). Lack of data is usual for the ex Yu countries and Albania, but not in Finland and Ireland.

Biology:

This interesting spider is common in the fields, steppes or woodland edges where builds an orb web. The web does not have retreat so spider sits at the web’s hub waiting for a prey. If something disturbs it, spider runs up a blade of grass or drops down on a thread. This creature is very hardworking species, every morning with same enthusiasm rebuilds the web. In nature adults can be found in late Summer.

Anatomy:

male palp: Median apophysis is slend and bifurcated female epigyna: scapus short, wide and looks very strong for more details please see this spider key: further details (Nentwig et al. 2010)

Diagnosis:

This is only representative of genus Mangora that lives in Europe. All his relatives live in North and South America (Mexico, Brazil, Argentina), and in Korea, China and Japan. That characteristic mark on the abdomen also makes species unmistakeable.

Importance for humans:

It can not bite, jaws could not penetrate the human skin
