Dark-Barred Twin-Spot Carpet

Fascinating facts about the Dark-Barred Twin-Spot Carpet

• In 1759 Carl Alexander Clerck gave science its first glimpse of the dark-barred twin-spot carpet, a moth that now spans the entire Holarctic. From the tundra of Alaska to the forests of Turkey, it blankets Europe, Siberia, Tibet, China, the Caucasus and even reaches as far south as North Carolina and California. Such a sweep means the species can survive a huge range of climates.
• Two full life-cycles spin out each year in Central Europe, with adults taking to the wing from late April through early July and again from early July to mid-September. The first-generation larvae appear in August-September, while their younger siblings emerge in June-July, and the first-generation pupae spend the winter in hibernation.
• Across its range, the moth splits into several named subspecies, each stamped with the year its distinct form was recorded: alaskae (1925) from Alaska, bilbainensis (1898) in Spain's Bilbao, infumata (1917) in Oregon's Crater Lake, malaisei (1929) on Kamchatka, and fuscata (1935) described by Nordström. These dates map a century-long trail of discovery, showing how naturalists have pieced together the moth's subtle regional tweaks over time.
• When the rare form ab. coarctata Prout appears, its median wing band shrinks to a razor-thin stripe only 1-2 mm wide, a stark contrast to the usual broader band.
• The caterpillars of Xanthorhoe ferrugata are picky eaters, feeding on a handful of low-lying plants: Galium, Stellaria, Campanula and Cirsium.
