leaves of shrub all brown

We had a beautiful shrub, sorry don’t know the name. Leaves are a dark red. I went to mow and all the leaves are now brown. There is a tiny nest around the leaves with tiny larvae. Only a few shoots remain with any color. Can I trim back the bush, eliminating all the affected areas? This has been a hardy and healthy shrub. They are not tent caterpillars. Hope that’s enough info. How far to cut back? It’s a 4 ft bush.

Yes, trim away the dead material and treat with Neem Oil. Destroy the material, do not compost.
