Two clips (close ups) of cinnabar moth caterpillars on ragwort (Senecio jacobaea): 1. 20 seconds, cinnabar moth caterpillar stretched out on ragwort stem, resting, light breeze. A fly enters at bottom and walks through the frame and out. 2. 10 seconds, Cinnabar moth caterpillar in the act of feeding on the top of a ragwort plant, blown by a breeze. The caterpillars of the cinnabar moth (Tyria jacobaeae) are striped black and orange-yellow, a warning colour and contrasting pattern that is explained as follows: the caterpillars absorb bitter tasting alkaloids from food plants such as ragwort that make such plants distasteful to most animals. The caterpillars themselves become distasteful to birds as a result. The bright, contrasting colours are a striking reminder to birds not to eat them. Full 1080p HD video from Canon EOS 7D.
