Not listed for Middlesex County on NJOdes, but IDed by Jim Bangma -- Z-shaped thoracic stripe, among other things. Apparently he doesn't update the range maps on the basis of photo submissions, though, because it's still not listed in Middlesex County.
I thought I posted this a long time ago, but apparently it slipped through the cracks.
Finally got a shot of the top surface of one of these! It was basking in the sun.
Godawful invasive -- originally used as an ornamental shrub & a windbreak, but escaped and widespread, in successional clearings. Covered with showy masses of little yellow flowers in spring.
Silvery Cinquefoil (Potentilla argentea). Low plant, flowers 1 cm across, roadside in an upland barrier-beach forest.
Cypress Spurge. Very pretty; unfortunately, an invasive weed. Haven't seen it many places, come to think of it; this is the same site where I photographed it last year, but the flowers are further along here; the leafy bracts are turning red.
These are all over the place here, but I've missed photographing them in bloom the past couple of years; finally got a shot.
