Hymenoptera, vespa solitária se alimentando em planta escandente da restinga.
There are 5 different species reported from Brazil. I only know synoeca septentrionalis and Synoeca surinama. Synoeca septentrionalis was recently described next to your aera. I think you need a close-up shot or the native specimen to get closer than Synoeca sp.
