What’s cutting big circles in my rose leaves?
The likely culprit is a leafcutter bee, which feed on other shrubs and plants as well. Leafcutter bees don’t live in colonies, but rather, individual female bees build brood chambers for their eggs, using those leaf circles as construction material. The damage is purely cosmetic, and since the bees only cut leaves for a short period, new growth will eventually hide the damaged leaves.
