~1.5 mm body with yellow legs and setae on upper thorax. On a Boerhavia coccinea leaf. A similar wasp with white spots on the shoulder/tegulae was observed ovipositing into mealybugs the previous day on the same plant and posted here: https://www.inaturalist.org/observations/181858741
Second record in western hemisphere
I found this on the wall of a paddle hut near the ground. The hut is bordered by brushy/marshy areas and a large park
I found him under a board by my security light in the morning. Very quickly flew away.
Attracted to my front porch lights either last night or the night before. Was found hanging from a spider web on the light.
collected from white snakeroot in my yard along with another cobalt hoverfly (also seen here)

Don’t currently have any dorsatus observations on this account so here one is. I found this mating pair in some brush in a remnant tallgrass prairie. Returned to the spot they were found after this photo
