Likely causes
Aphid infestation
Most likelyHow to tell: You will see small, soft bodied insects clustered on the flower stalks or new growth. The plant may look slightly stunted or have sticky residue on the leaves.
What to do: Spray the plant with a steady stream of water to knock them off. If they persist, use a mild insecticidal soap once a week until they are gone.

When to worry
A few aphids are usually manageable, but you should worry if the flower buds start to deform or fail to open. If the infestation covers the entire plant, it is time to intervene.
Stopping it coming back
Keep your hawkbit in full sun to encourage strong growth. Avoid over fertilizing, as this creates the soft tissue that aphids love.
