They like one of my rose bushes best. it is so weird to see these perfectly round pieces cut out of the leaves. Kind of cool. I have had them for years to no ill effect.

They are new to me this year. I haven't seen the bees, just the cuts. I did some searching and found they are actually considered beneficial as pollinators. The damage is considered of no consequence, although one of our roses is really chewed up.

Yesterday, I had the great experience of watching up close and actually hearing the bee cutting off a round-oval piece of leaf edge while sitting on a log in the woods. It was a small green, albeit tasty looking to him, some type of bush next to my log. Off he flew with it and came back about every 5 minutes and sliced and diced another hunk of leaf and flew away. Looking him up, he is called the " Leaf Cutting Bee". Mine was gold and black striped and resembled a miniature bumble. There are many different looking types. Just type in 'leaf cutting bee' and lots of websites come up. They are great pollinators and do no harm. It says they can out pollinate honey bees!
