About Amyna stricta
Amyna stricta, commonly known as the eight-spot moth, is a species of owlet moth in the family Noctuidae. It is found across North, Central, and South America. In 2015, the New World population previously classified as Amyna axis was recognized as a separate species and reclassified as Amyna stricta. It is common in southern North America, ranging from Florida to Arizona. It is a regular migrant to mid-eastern United States states, and has been rarely found as far north as Wisconsin, Ontario and Quebec. It migrates northward annually during late summer and fall. The MONA (Hodges) number for Amyna stricta is 9070. The larvae of Amyna stricta feed on plant species from the following genera: Amaranthus, Croton, Celosia, Digera, Helianthus, Chenopodium, Spinacia, Ipomoea, Ricinus, Arachis, Crotalaria, Medicago, Phaseolus, Hibiscus, Cardiospermum, Solanum, Corchorus and Parasponia. It is an irregular minor pest of mung beans (Vigna radiata), black-eyed peas (Vigna unguiculata), lucerne (Medicago sativa) and soy beans (Glycine max). The species' prevalence may be under reported because its caterpillars resemble caterpillars of Chrysodeixis species.
