Likely causes

Aphids
Most likely
How to tell: You will see small green or black insects clustered on the stems and undersides of leaves. The foliage might also look sticky or distorted.
What to do: Spray the plant with a strong stream of water from your hose to knock them off. If they persist, apply insecticidal soap every 5 to 7 days until they are gone.
Environmental Stress
Possible
How to tell: The plant looks weak and is struggling to grow, making it more attractive to pests. Check if the soil is too dry or if the plant lacks enough sun.
What to do: Ensure your vetch gets full sun and consistent water every 7 to 14 days. A healthy plant is much better at defending itself against insect attacks.
