Spiders' Webs, Hoar Frost and a Festive Walk

Spiders’ webs are great structures for children to look at, copy the patterns and to view spiders.  Back in September the spiders were hard at work in the garden weaving away.  It was impossible for me to pass through my archway without getting threads tangled in my hair.  However by the time I got my act together to photograph some of the webs the spiders seemed to have all miraculously disappeared. 





So at Christmas I was delighted to find some webs sparkling with hoar frost.  The frost shows off the patterns perfectly.  Apparently an orb web is the one we most commonly see and link with spiders in the UK.  The spider anchors silk lines that radiate from a centre, to grass, stems and other structures. It then weaves a sticky spiral of silk around the centre.  Threads are then woven round to strengthen the outside of the web.  It is the stickiness of those threads that attracts water from the air so making water droplets.  There is more information on spiders and some activities for kids by The British Council.

That same day the hoar frost was so amazing that the camera was a must for a walk around the garden and then further afield.  This was certainly a snowy glittery Christmas for us.
