Caterpillar Sitting

Whilst J and D are away in my van I agreed to be J's caterpillar sitter.  He has a butterfly house in the back garden where he's got several Swan Plants and a host of voracious Monarch caterpillars.  Unfortunately I didn't take my tripod with me today when I went to tend the flock (hence the not-so-good image) - will have to remember it in a couple of days time when I go back.
