Transplanted saw fly caterpillars

I was pleased to move these to a new location from yesterday position. They were in my friend's garden and I wanted some in mine. They live on solomons seal and do not do any damage to any other plant. Although they munch the solomons seal it recovers and flowers the following year. I love to see caterpillars in my garden. I plant nasturtiums specially for the caterpillars of small white butterflies.
