Latticed Heath

Fascinating facts about the Latticed Heath

• Latticed heath moths trace their scientific name back to the 1758 10th edition of Linnaeus's Systema Naturae, where the genus was erected in 1758. A 2002 revision of the tribe Macariini by Malcolm J. Scoble reshuffled the group, showing that true Semiothisa species belong only to the Americas and confirming that this moth belongs in Chiasmia. Later molecular studies have reinforced that placement, anchoring the species firmly in modern taxonomy and showing how DNA can rewrite centuries-old classifications.
• With a wingspan of 20-25 mm, the latticed heath. Its wings shift from yellowish to white, overlaid with a lattice of brown lines that give the moth its common name; the lines can be thin or thick, and some individuals appear almost entirely dark brown.
• The latticed heath spans three continents, occurring throughout Europe, the Near East and North Africa, then marching east across Russia, Siberia, the Amur River, northern Iran, Kazakhstan, China, Korea and Japan. Its ability to thrive in open habitats, from grassland and moorland to waste ground, means it shows up in both pristine meadows and urban edges, making it a useful indicator of how moths adapt to human-altered landscapes across a huge geographic swath.
• In Britain the latticed heath squeezes out one or two generations each year, with adults on the wing from May through September. Though they are primarily day-flying, they are also drawn to artificial lights at night. The caterpillars, bright pale green with distinct white lines, munch on a menu of bedstraws and legumes such as clovers, trefoils, lucerne and meadow vetchling, mainly in June-July and again from mid-August to September. After feeding, they pupate and spend the winter underground as a pupa, emerging when warmth returns.
• Four subspecies of the latticed heath have been formally described, each bearing the name of its discoverer and year of description: the nominate Chiasmia clathrata clathrata (Linné), C. c. centralasiae (Krulikowski, 1911), C. c. djakonovi (Kardakoff, 1928) and C. c. kurilata (Bryk, 1942).
