Dark Sword-grass Agrotis ipsilon


Family Noctuidae » Subfamily Noctuinae » Agrotis ipsilon (Hufnagel, 1766) 73.327 (BF2091)
Forewing length 15-25 mm. This is one of our regular migrants, and numbers can vary year to year. Its markings very much resemble knotted wood, which makes for good camouflage. The larvae feed on or below the ground and at night, on various herbaceous plants and their roots. Due to its retiring nature, breeding in this country has never been reliably proven. Mostly seen August to October, but can also be observed from March to November. It can turn up almost anywhere, but most frequent in the south.
