A description of the web / nest rather than the spider, which I couldn't see in any detail other than that it was dark coloured and appeared to have a large round abdomen. Size approx. 12 - 15 mm. The web was built at the top of the stems of four or five tall grasses by weaving the grasses together with silk. In the centre and attached to the web and one grass stem was a round hollow ball of silk about 25 mm across with a hole in the underside, presumably through which the spider could emerge. The spider was sitting in the centre top of this ball. Is this web characteristic of any particular species? Can anyone shed any more light?
