Another week passes and this post must go up. A Garden Tiger moth (Arctia caja) turned up. What a wonderful moth it is. Arctia from the Greek for ‘bear’ – the hairy larva is called the ‘wooly bear’ –and caja is taken from a Roman lady’s name (the female of Caius). Linnaeus used feminine names for species with brightly-coloured hindwings and this moth certainly is a suitable candidate. The red colouring is so intense. The caterpillars have now embraced a dandelion leaf diet and they are increasing in size at an alarming rate. One larval skin-shedding has taken place and the hairs on their backs grow longer and longer.
