Technical description and variation

Heliothis peltigera has a wingspan of 29–40 mm and forewings reaching a length of 16–19 mm. These moths are rather variable in pattern and colour.

On middle of costa there is a reniform grey dot, with dark brown edge and centre, joined to a brown mark. A brown band appears between outer and submarginal lines. A black dot is present below vein 2 before margin. Hindwings show a broad brown-black marginal border, containing a pale blotch between 2 and 4. Cellspot is dark and fringes are white. Larvae are reddish grey or ochreous, dotted with white. Dorsal and subdorsal lines are dark, while spiracular line is white.
