Explanation of Names
Latin: clava (club) + forma (form) = club shaped
A Claviform Spot is a club-like or elongated spot on the FW (forewing) of Noctuid moths, extending from the AM (antemedian) through the submedian area, toward the PM (postmedian) line.
It is located next to or may be touching the orbicular spot.

Sometimes it may be round-shaped or circular. Often it is absent, just a small dot or maybe a thin dash.
