ID please. The caterpillar, rescured from a water butt located below a Forsythia bush from which it had appeared to have fallen from. Said bush also has sown leaves with little green caterpillars housed within which may or may not be same caterpillar that I rescured as 'my' caterpillar was somewhat larger. My picture shows green caterpillar with inset of 'tented caterpillar. Are they one and the same? Many thanks.
