Went through almost all the hives in the past two weeks and have noticed that wax moths were in most of them on the bottom boards. The smaller hives had much more while the larger hives had very little as the larger population of bees are able to control the wax moth from invading. But anyways, on your next inspection, tilt your brood boxes and take a peek at the bottom board. Or if you use screen bottom boards, check the tray.
Last week we went camping in Santa Cruz/Watsonville at Manresa State Park. Couldn’t help it and snapped a picture of a bee working the mustard flowers.
