The hindwing is translucent white with dark veins and ta dark terminal line. with yellow striped armyworms, Spodoptera ornithogalli (Guenee). The white mark below the reniform spot forks to form a sideways Y shape. Black triangles are positioned above the yellow stripe on most abdominal segments. Less distinctive stripes are below that, including a pink stripe above the prologs. Contact individual photographers for permission to use for any purpose.

The forewing is brown or gray with bluish shading, white lines and black markings. Adults are difficult to distinguish from their relatives (such as the fall armyworm), but the larvae are distinct. praefica are white or gray and have a small brown dot on the ventral side. The Yellow-striped Armyworm Moth has a wingspan of approximately 1.25 to 1.75 inches. praefica's fore-wings are paler and lack the blurry white stripe. It is similar in appearance to Spodoptera ornithogalli, but S. Yellow -striped Armyworm : They have two large yellow stripes and many smaller ones. Sixth instar larvae burrow into soil to pupate. Young beet armyworms hatch, web up, and feed together on leaves. Eggs hatch in about 6 days, and larvae feed for 3 weeks. 45 and 46) and yellow-striped armyworm moths lay eggs on leaf surfaces in masses covered by a whitish, velvety material. Egg masses placed on foliage, trees, or buildings. The wingspan is 35–40 millimetres ( 1 + 3⁄ 8– 1 + 9⁄ 16 in). Adult emergence begins in early April and continues into May. As of 4 October 2021 it is absent from the EPPO ( European and Mediterranean Plant Protection Organization) area, but is considered a high risk for invasion there. I didn't rear these to adulthood, but I'm so glad that you got to see your Noctua pronuba through their development.Spodoptera praefica, the western yellow-striped armyworm, is a moth of the family Noctuidae found from British Columbia to California, east to Utah, and north to Alberta. Spodoptera ornithogalli (yellow-striped armyworm, cotton cutworm) is a moth of the family Noctuidae found in Guadeloupe, Marie-Galante, Saint Kitts, Dominica, Cuba, Dominican Republic, Mexico, Guatemala, Costa Rica. I've added a few photos which show the details of the anatomy I used to identify these fellows. The yellow-striped armyworm moth, which has the enchanting Latin name Spodoptera ornithogalli, is a noctuid moth living all over the southern United States (from California to Florida), and much of South America. I'll paraphrase about the Yellow-striped Armyworm from Wagner's caterpillar book: Abdominal segments frequently with set of four, thin, white stripes beneath subdorsal stripe.Often with a black spot on A1 above spiracle.Many have rusty line beneath each spiracle which may join to form thin subspiracular stripe. This spot is often (though not always) seen on the Yellow-striped Armyworm, but not on the Large Yellow Underwing. The way that I tell them apart is to look for a large black spot on the side of A1 above the spiracle. You're absolutely right to point out that the Spodoptera ornithogalli larva and the Noctua pronuba larva can look incredibly similar. After people and pets, I would consider the most devastating loss to be the loss of my books. The production of this crop in open field is constrained by major pests like fruit borer, yellow striped armyworm and caterpillar. Avoid confusing this insect with either the true armyworm (Mythimna unipuncta), which we are used to seeing in May-June in vegetative corn and other crops in particular, note that fall armyworm is much more capable of causing meaningful defoliation in soybean than the true armyworm. I can't begin to tell you how sorry I am about your fire.
