We think it has something to do with the Marsh Discovery Trail repairs. (Thanks to Dennis Cheeseman for pointing this out…)

Last week, we posted a photo of a Cicada Killer, a wasp that preys on (you guessed it) Cicadas.

At Butterfly Day, folks witnessed a wasp dragging a spider all the way across the road, for similar nefarious motives — and managed to get photos of same. Good times again.

According to Bergen County Audubon Society’s bug consultant, Hadel Go, this gal “looks like Tachypompilus ferrugineus,” a spider wasp (aptly named, though “spider killer” might be better if she wanted to jazz up her image).

More on this wasp here.

Natalie Gregorio took the above photo of the wasp in action. Roy Woodford took the photo below. (Thanks, Hadel, Natalie and Roy!)
