When I was in the Camargue the autumn before last there were these spider's web-like threads all over the place. They were usually just single threads and sometimes up to a cm thick. They stretched out across the track we were cycling along to the extent that we ended up plastered in them. They were sticky like spider silk so the logical answer is that they were made by spiders, but I'm not aware of a species that produces such vast quantities of silk. This stuff was was draped along hedgerows and sailing for hundreds of metres in the sky - it was everywhere. I don't remember seeing any spiders or any other creature that might have been the cause. It was just very strange that there was so much of it. From other posts on iSpot I've seen that the Cherry Ermine Moth can produce large quantities of silk, but I don't think that this can be the cause in this case. Does anyone have any idea of a species that could have produced these threads, spider or otherwise? I wish I'd taken more photos because this one doesn't really give a good illustration.
