pronged fork pointed away from the body, AND

of the genus Spodoptera especially if the moth was found on an appropriate
host:
• White patch on the highest point of the forewing, AND
• Oblique whitish band, extending from mid-costa to mid-forewing cell, AND
• Forewings with circular and kidney-shaped spots (could be partially
hidden by the oblique band), AND
