[edit] Description
Males reach a body length of about six, females up to eight millimeters. The female has a brown and whitish cephalothorax, and an opisthosoma with a distinct pattern of black diagonal spots, sometimes with a white outline. The male is in contrast almost black with a copper-like gloss. His face features a horizontal pattern of black and white stripes. While males are found very frequently, females often hide in their retreats, for example between rolled leaves. During late summer she guards her egg sac there.[1]
[edit] Distribution
They prefer more or less moist areas, like moust meadows, riversides or some forests, but they are also found in dry places. In Central Europe they are almost as frequently found as Evarcha falcata.[1] The range extends through the whole Palearctic up to Japan. In England they are only found in the central and eastern South[2].
[edit] Name
The species name is possibly derived from Latin arcus "bow", with the meaning "arched", referring to the arched abdomen.
