Fascinating facts about the Dark Arches

• First recorded in 1766, the dark arches moth measures just 46 to 54 mm across its wings, yet its cryptic forewing shades range from pale grey-brown to almost black. This modest size hides a long taxonomic history, linking the species to the 18th-century work of Johann Siegfried Hufnagel.
• The dark arches' forewings display a striking black mark near the dorsum and a pale zigzag subterminal line, while the hindwings stay whitish with darker veins and a shaded margin. These markings, including a black streak from the wing base and pale, zigzag submarginal lines.
• Across most of Europe, from the British Isles to Siberia and Mongolia, the dark arches thrives, skipping only the far north of Fennoscandia and the southern of the Iberian Peninsula and Greece. In the Alps it climbs to 2,500 m.
• Active under the cover of night, the dark arches takes flight from June through August in the British Isles, with a surprise second brood sometimes appearing in September and October.
• The caterpillars of Apamea monoglypha live underground, feeding on the roots of a variety of grasses such as tussock, orchard, rye, reed grasses and sheep's fescue. They spend the winter as larvae, overwintering.
