bugs on columbine
This photo is so blurred we cannot see the insects (in fact, this doesn't look like most columbines.) However, it may be aphids, which you can control with horticultural soap or oil. Read the label carefully for dilution rates. Do not use strong pesticides which will kill your beneficial insects. Beneficial insects help keep aphids under control.
Please send us a sharper photos and we'd be glad to help further.
