It was windy, cold and sunny as five volunteers completed this week's survey. Just as vertebrates leave tracks, scat or other signs of their presence, arthropods also produce clues to their identities. Below are three such examples: a silk retreat covering eggs, a cocoon enclosing a pupa and chew marks left by a twig girdler (a kind of longhorn beetle) on a tree branch.
