About Zanclognatha lunalis (Scopoli, 1763)
This species is described here under its synonym Zanclognatha tarsiplumalis Hbn. The forewings are grey-brown with a faint purplish tinge. The outer lines are dark brown, fine and faint. The inner line bends on each fold and is primarily vertical. The outer line is widely excurved, irregularly crenulate beyond the cell, and insinuate on the submedian fold. The subterminal line is stronger, oblique starting from before the apex, straight, and edged outwardly by whitish. A conspicuous slender brown lunule sits at the end of the cell. The terminal line is dark, edged by a bright white line at the base of the fringe. On the hindwings, outer and subterminal lines are only marked on the inner marginal half of the wing. The larva is reddish yellow, with paler segmental incisions. It has a red-brown dorsal line, and three finer, parallel, pale reddish subdorsal lines that are irregularly crenulate or hidden within blotches. Below the black spiracles, there is a double irregularly crenulate lateral line. The wingspan of the adult moth measures 32–36 millimetres, equal to 1.3–1.4 inches.
