My grape vine (Italia) has a plague of these tiny beetle, which look black, but have almost metallic stripes.
They also have black caterpillars. I presume these then turn into beetles, which lay eggs which....etc., although my biology is not very good.
They have virtually stripped a very large vine, and I cannot treat them, as we are eating the grapes at the moment.
I would like to identify them, and to find a way of getting rid of them, other than using pesticides, as they appear just before the grapes ripen. Advice please!
