Hard to see in pic above but my laburnum is being attacked by something that is eating the leaves. Leaf mining insects? or aphids?

What do i do, cut off the damaged leaves and what can i treat it with?. New buds a re coming out too so it must be fairly OK

Thanks

Hard to say without a clear pic, but Laburnum blong to the leguminaceae family and thus behave like peas. They suffer commonly from Calcium deficiency which causes balckening of shoot tips. Could this be a possibility?
Is it possible to see a closer pic?

sorry to disagree with you gardenman. Calcium deficiency unlikely to cause holes in leaves. I am not sure of the cause but it might be Capsid bug. AQs this is a forum and everybody is entitled to their opinion I always like to see people making a stab at solving problems.

Looks like plain and simple slug damage to me.
