COMMON BLUE


Perhaps not the perfect name: it’s not that frequently seen in Otley – it’s more that it’s the most widespread of the British blues – and the female can be quite brown. The caterpillar has the classic green with yellow stripes colouring. They secrete a sugar-rich liquid called honeydew, which ants like to eat, in return for which they offer protection, sometimes even dragging a chrysalis into their nest.
