Once my Echenacia produce buds they are attacked by small brownish beetles that distort the buds and cripple petal production. I tried researching what the insects were with no clear results. They are not Japanese Beetles. What can I do to prevent this infestation? My Echenacia are coming up with green leaves and looking good. Is there a preventative or systemic treatment for these bugs? Last year I used insecticidal soap to remove and try to eliminate them. Any help would be appreciated.

Japanese beetles and eriophyid mites are two known insect pests of echinacea. We would need to see a photo of the insect in question in order to make an accurate diagnosis. Can you send us photos of the problem, please?
