can be distinguished from other Apoda by the straight, linear wing patterns referenced in the species name. From A. y-inversa (Yellow-collared Slug Moth), which has a prominent yellow collar, A. rectilinea lacks such bold markings. Caterpillars may be distinguished from other Apoda larvae by association and subtle morphological differences, though specific larval diagnostic features are not well documented.
