I found this little dude (Ezekiel) on the ground on a walkway, seemed to be having trouble flying. Kept sporadically buzzing wings and was unable to fly more than a second or so, so I persuaded her onto my jacket sleeve to avoid any possible stinging or biting and moved to a nearby flower bed to deposit her safely. She seemed very chill on my sleeve and didn't want to get off. She much preferred climbing around on my arm and coat than move to the flower I was positioning my arm next to. When I finally got her to move to the flower she seemed content and stopped moving for a moment before she proceeded to clean herself for a good minute or two while I took some more pictures. After a rest, Ezekiel flew away just fine. I estimated the size from the picture of the little dude on my jacket and measurements of my fingers.
