I have something eating my Laburnum Tree, Climbing Hydrangea and Viburnum Tinus shrub. I took cuttings to the nursery and they said it looks like tent caterpillars because the bites from the leaves are quite large. However, I cannot find any evidence of either that little critter nor his tent. They recommended I spray with Safer's Trounce which I have done, so I will keep an eye on what happens if anything. Also, my Butterfly Bush is being eaten they think by earwigs. If anyone out there could offer some advice on diagnosis and/or treatment, I would be so grateful.
