Spider's web in grass

Nature seems to be more obvious to people since lock down, there seems to be a growing awareness of all things green or tweety, people convinced the birds are louder and the spring blossom more brilliant than previous years.

This new found appreciation means more natural phenomenons are being noticed, like for example the horizontal spiders webs seen in the grass in the morning, often covered in droplets of dew.  Sheet webs as they are known are the work of the Linyphiidae family of spiders, this is a huge family of spiders which make up 40% of our native British spiders. The well known Money spiders are part of this family.

The spiders make horizontal webs in the grass with guide threads above and below the web. These guide threads deflect their prey into the web where the spider waits patiently.

It’s also this group of spiders which do the ‘ballooning’ method of dispersal. The spider lets out a strand of silk into the air, wind currents lift the spider and it ‘flies’ up and off to find new territories. These spiders have been detected in atmospheric data as high up as 3 miles!
