Common Heath

Fascinating facts about the Common Heath

• The common heath moth inhabits a vast trans-Eurasian belt that stretches from the Iberian Peninsula in the west across central and eastern Europe and reaches as far east as Siberia and Sakhalin. Its southern limit extends into the northern Mediterranean region and the Turkish part of the Black Sea area, giving it a truly pan-Palearctic distribution. This broad range means the species encounters a wide variety of temperate habitats throughout its range.
• Among the common heath's many colour forms, an exceptionally rare specimen with six wings has been documented, illustrating the extreme morphological flexibility of the species. In addition, a gynandrous individual was recorded in which the right side displayed the pattern of a small dark female while the left side matched a typical male, each side bearing short pectinate antennae.
• In the British Isles the common heath produces a single generation each year, with adults taking to the wing from May through June. Occasionally individuals may be seen later in the season.
• Female common heath moths are usually brown with a dusting of white, but some individuals are almost entirely white marked only by a series of brown crosslines.
• The common heath caterpillar is a slim, smooth larva that can reach up to 30 millimetres in length, a modest size that helps it move easily among low-lying vegetation. Its colour is highly variable, ranging from brown to yellowish, grey to violet-grey, with a dark dorsal line and light, wavy side stripes that break up its outline.
