spirea bushes

Question

Have 4 small spirea bushes planted in front of my house. They draw a large amount of flies. Can you tell me if this is normal or why this might happen?

Answer 1

Fortunately this is normal. The flies you are seeing are probably syrphid flies, also called flower flies. These are important pollinators of many plants, including spirea, and so they are actually beneficial to the plants.
