The only Ghost I ever saw — Ghost Moth

The only Ghost I ever saw 1
Was dressed in Mechlin-so-
He wore no sandal on his foot-
And stepped like flakes of snow-

His Gait-was soundless, like the Bird-5
But rapid-like the Roe-
His fashions, quaint, Mosaic-
Or haply, Mistletoe-

His conversation-seldom-9
His laughter, like the Breeze-
That dies away in Dimples
Among the pensive Trees-

Our interview-was transient-13
Of me, himself was shy-
And God forbid I look behind-
Since that appalling Day!
(F.331/J.274)

Why is the ghost-moth so called? Because of its singular flight in the twilight hour, haunting, as it were, one particular spot—wherefore the fancy of some collector probably considered it a spectre-like action. ─ Knowledge for the People (1831)

Humuli (Ghost Moth): wings yellow, striated with orange; those of the male with white. It inhabits Europe. The Caterpillar feeds on the roots of the hop and burdock: it is of a cream colour, and somewhat glossy; the head is nut-brown; on the back, close behind the head, is a brown, shining mark, of a hard, callous substance. It changes, in May, to a dark brown pupa, and the Moth appears in June. It flies in the dusk of the evening, hovering up and down, in one particular spot, for a long time. It is often seen in church-yards; whence its English name. ─ The Young Lady's Book (1829)

The Ghost Moth, Phalaena Humuli, feeds upon the roots, and the mottled Orange Moth upon the stalks. ─ A Botanical Arrangement of All the Vegetables Naturally Growing in Great Britain (1776)
