Nice shooting the smaller ones are this springs young. They grow pretty quick, don't know how your time schedule works but what is very effective is to scout out the holes. You will usually find them as you did in dense vegetation, or hidden under or by structure. The bot flies also will give away their location in vegetation, and often they will conceal their holes with addition vegetation, and debris. After a day of foraging they return home. I make the rounds on holes, giving 5-10 minutes of attention to each and move hole to hole. this is done about an hour before dusk. On one piece of nursery the workers pointed my attention to Mulberry trees, it was a feast as they ate both the leaves and berries. Looking up was the last thing I would have thought. I enjoy your vids, and applaud your video graphic commitment, I would have grabbed the gun before the camera.
