Zygiella atrica

Description

Size female about 6.5 mm, male smaller about 4 mm. Most (but not all) specimens have more red-brown colouration than Zygiella x-notata, but the species need to be separated by an expert for identification purposes. Very difficult to distinguish from Z. atrica. Specimens found on window frames or car door mirrors are unlikely to be Z. atrica (but it's not impossible), but those from vegetation could be either.  Zygiella x-notata and Zygiella atrica need to be separated by an expert for identification purposes. Please state where the specimen was found when submitting a record.

Habitat

Vegetation and sometimes gardens. Unlike Z. X-notata, this spider is usually found a little way away from houses and human habitation, on bushes and rocks.

When to see it

Female can be seen all year round. The male is more likely to be encountered during the summer.

Life History

Zygiella atrica, like other Zygiella species, builds an orb web with two missing sectors and a signaling thread in the centre of those, leading to its hideout, whereas the young spiders build a complete web. Females of this species are among the few British orb-weavers to build webs all year round.
