Cinnabar Moth Caterpillars on Ragwort
Comments(2) # Cinnabar Moth Caterpillars on Ragwort london e17

When I showed you the rather stunning Cinnabar Moth, MJ over in Canada did some research to find out that they'd been introduced over there in an attempt to try and control Ragwort which, due to its poisonous nature and the way in which it grows amongst other animal feed-crops, has become the bane of many horse-owners and other livestock farmers. Leaving aside the potential risk of introducing alien species I promised I'd show the caterpillars as soon as I came across any. So here they are, and almost as striking as the adults they will become. It is whilst eating the Ragwort, incidentally, that they are able to absorb but not be affected by the alkaloid poisons that gives them protection from predators. Canon EOS 40D
