I was looking at my roses and I noticed that one flower had about 8 devil beetles in it. A little later, I noticed a sparrow and a bluebird hovering near the flower and picking at it. The sparrow landed on the ground below the flower, then flew away to its nest behind a window shutter. Some happy babies were feasting on devil beetles.
It is the first time I saw this. I won't zap the devil beetles with insecticide now.
That is really a good feeling knowing the devil beetles are being devoured.
