Amyna axis
species of insect
Amyna axis, the oriental eight-spot, is a moth of the family Noctuidae. The species was first described by Achille Guenée in 1852.
Distribution
It occurs in Africa, temperate Asia, Australia and the Cook Islands. The New World population of Amyna axis was determined to be a separate species, Amyna stricta, in 2015.
The moth migrates north each year in late summer and fall.
Food plants
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). Its prevalence may be under reported due to the resemblance of the caterpillar with those of Chrysoieixis species.
Early stages
The larvae are thin bodied and have faint white stripes and two pairs of ventral prolegs. At low densities of groups, caterpillars are pale green.

Why this record matters
“Amyna axis” is worth following because a concise public description often conceals a longer documentary argument. Here, Amyna, axis and species provides the most credible route into that argument.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Mar 8, 2026. The linked authority identifier is Q4749565. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1852 and 2015.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
