These are sculptures by New York sculptor David Rogers. Yes, you see correctly, these are giant bugs made out of wood, or more precisely various combinations of whole trees standing or dead, green saplings and other forest materials. Some quote from him:

“These little creatures which we often take for granted outnumber us one million to one. Many live in communal groups working as one for the common good of all. Their ranks include engineers, soldiers, weightlifters, weavers, hunters, stalkers, gatherers, and even royalty.

When you take this remarkable and diverse group of “hidden gardeners” and recreate them on a gargantuan scale using all-natural materials, you have the Big Bugs. The effect is a role reversal of dimension and perception.”
