Some recent posts on a Facebook page and on the Wild About Britain forum, as well as finding some aquatic caterpillars on some of the currently daily pond dips at work, made me realise I never posted (or even uploaded) my photos of these interesting creatures.
These are the caterpillars of one of the china mark moths. They build cases ratehr like caddisfly larva, with which they are often confused, and those that I have photographed seem to favour building cases out of duck weed. All taken with my Photographic aquarium set up
You can find out more about these creatures here on Dave Hubble’s excellent blog.
