Ghost Moth (Hepialus humuli)

The ghost moth indigenous to different parts of Europe gets its name because of the hovering flight pattern displayed by the males as they attract females at night. Their white wings make them look like tiny specters moving up and down as they are in motion.

Described by Swedish botanist Carl Linnaeus in 1758, the ghost moth has two subspecies: Hepialus humuli humuli and Hepialus humuli thulensis.

Description and Identification


The caterpillar has an opaque, white body with a reddish-brown head and brown markings all over. They eat plant rootlets during their initial instars, moving on to larger roots and other parts of the plants’ lower regions as they grow older. The larva has a prolonged development period, taking 2-3 years.
