The Hammock Weaver

Photos from the past.  On a misty autumn morning, fine droplets of water cling to spider silk, revealing the huge number of webs on the gorse. This photo is from 2010; I haven't taken a better one of this phenomenon since. But a year ago I took some shots of the creature that makes all these webs; the Common Hammock-weaver, Linyphia triangularis.

You can see the distinctive tuning-fork mark on its thorax. This spider weaves horizontal platform webs with strands running up to the foliage above. A flying insect that hits those strands might fall onto the platform below; and underneath it, the spider waits. It can quickly run along the underside and bite its prey through the web. The spider can deal effectively with substantial prey ... This one is in the same place I took the top photo.
