Body length up to 12mm. The female of this spider is considerably fatter than the male. Very similar to A. similis, and can only be safely identified by microscopic examination of the genitalia, hence these images are only representitive of the species.
It feeds on insects caught in its web. When the spiderlings hatch the mother dies and provides nourishment for her growing young with her own remains.
The adult females are seen all year round, the males June to November. Not so much usually associated with human association compared to A. similis, but can be occassionally found in similar situations. Normally found in the hollows of old tree trunks in woodland, and under rocks, stones and logs. A common and widespread species throughout Britain.
