Amyna stricta, the eight-spot moth, is a species of owlet moth in the family Noctuidae. It is found in North, Central, and South America. The New World population of Amyna axis was determined to be a separate species in 2015, and is now classified as this species, Amyna stricta.
The moth is common in southern North America, from Florida to Arizona. It is a regular migrant to the mid-eastern states, and rarely as far as Wisconsin, Ontario and Quebec. It migrates north each year in late summer and fall.
The MONA or Hodges number for Amyna stricta is 9070. The larvae feed on Amaranthus, Croton, Celosia, Digera, Helianthus, Chenopodium, Spinacia, Ipomoea, Ricinus, Arachis, Crotalaria, Medicago, Phaseolus, Hibiscus, Cardiospermum, Solanum, Corchorus and Parasponia species.
It is an irregular minor pest of mung beans (Vigna radiata), black-eyed peas (Vigna unguiclata), lucerne (Medicago sativa) and soy beans (Glycine max). Their prevalence may be under reported due to the resemblance of the caterpillar with those of Chrysoieixis species.
The larvae are thin bodied and have faint white stripes and two pairs of ventral prolegs. At low... Wikipedia →
