The adults are attracted to light and feed on foliage.

They can be an agricultural pest affecting a wide range of crops because their larvae feed on plant roots and can weaken or kill the plants.

As in other members of this genus, the males have large distinctive antennae consisting of several lamellate plates, which they close up when threatened.

The underside of the thorax is covered with brownish hairs.

Larva: The grub can grow up to 2 inches with 3 pairs of legs, with a white body and brown head.
