Scoliid Wasp (male)

Habitat:

gardens, fields, parks.

Notes:

Spotted this male just staying put on a cold afternoon. By the way, when looking at the picture at home, I noticed the other insect on the upper leaf. Very small, kind of see through green, long antennae, doesn't appear to have wings. Anyone has any ideas??? I don't even know where to start with one in bugguide.
