Insects like plants with open access to pollen and nectar so, as said above, no doubles as they are often sterile. There are plenty of clematis that like shade. You could try rose Ballerina which has open blooms and tolerates shade. Just make sure it's planted in good soil and gets a regular top dressing as roses, like clematis, are hungry plants.
Aquilegias are good, foxgloves (bees not butterflies), astilbes if the soil is not too dry, primroses and primulas for early season nectar, japanese anemones, sweet cicely, geranium phaeum, lobelia cardinalis and simple busy lizzies. Try heliopsis and eupatorium if you have some sun on the bed.
