Square-spot Rustic

Xestia xanthographa

Very common & widespread in Britain, mainly nocturnal.

Larva greenish ochreous, with pale dorsal and subdorsal lines edged with dark; between them a row of oblique marks. 

The nocturnal Larvae feed during the winter, mainly on grasses, but also on other low-growing plants.

The species overwinters as a Larva.

Forewing dull brown; the upper stigmata with pale annuli, the reniform sometimes wholly pale, the orbicular round; claviform absent; hindwing ochreous white, suffused with fuscous towards termen only in Male, more broadly in Female.

This Moth flies at night from July to September and is attracted to light, making it susceptible to light traps, and sugar.
