'something' on tree

'something' on tree

Observation - 'something' on tree - Global. Description: These white 'things' were on several trees. Images 0949 and 0950 were the same tree. You couldn't actually feel them as they were so small. I didn't notice them on the images with the spider until later. I was wondering whether they were eggs or maybe
