Square-Spot Rustic

Fascinating facts about the Square-Spot Rustic

• The square-spot rustic's most eye-catching trait is a 30-40 mm wingspan crowned by a large, pale, squarish stigma that gives the moth its name. Its forewings sit in dull brown shades while the hindwings range from pale to dark grey and finish with a whitish fringe. This combination of size and the distinctive pale square spot lets naturalists spot it even among the many brown moths that flutter at dusk, turning a routine night-survey into a reliable identification.
• Adults take to the night sky from July to September, a flight window that aligns with the British summer. During these months they are strongly attracted to artificial light, which makes light traps an effective way to monitor their numbers, and they also sip sugary baits.
• The caterpillars are greenish-ochreous with pale dorsal and subdorsal lines edged in dark, and a row of oblique marks between them. They munch on a mixed menu of plants, from low-lying bedstraw to sturdy oak and willow, plus a variety of grasses, and they do not pause for winter. Instead, the species overwinters as a larva, staying active and feeding throughout the cold months.
• Colouration in the square-spot rustic is highly variable. While the typical form shows dull brown forewings, several named aberrations exist: ab. budensis displays a grey ground colour; ab. elutior shines in cinnamon brown or yellow-grey; ab. palaestinensis is paler but with sharper markings; and the darker ab. obscura and ab. nigra appear reddish-black or grey-black, especially in northern Scotland where the hindwing can turn blackish.
• From North Africa to Europe and across the Palearctic (excluding China) into North America, this moth occupies a vast stretch of the Northern Hemisphere. In Britain, with a distribution that covers most of England.
