Hornet-like insect, very big, about 1 inch and a half. It was sucking up the wood from the fence.
No interactions present.
Does it use the wood to build the nest?
I think the red legs threw me there :)
They gather wood pulp for nesting. Check out the Information sheets on hornets and D.media at http://www.bwars.com/bwars_information_sheets.htm
