Tons of gulls that refused to get off the runway! Planes were landing and taking off pretty constantly, and the airport even set a guy in a truck to drive down the runway and try and chase them off, to no avail. They'd fly off a little ways and come right back.
unfortunately this one took off before I could get a better shot
terrible photo, but I am pretty sure of the ID
looks like a mimic of the Sphecodes sweat bees
