Xylorhiza adusta can reach a length of about 35-40 millimetres. The background color of this mimetic bark-like long-horned borer is greyish-brown, with dark brown longitudinal lines on the hairy elytra.

This widespread species can be found in Cambodia, China, India, Laos, Malaysia, Myanmar, Sri Lanka, Sumatra, Taiwan, Thailand and Vietnam.

Xylorhiza is a genus of flowering plants in the sunflower family, are known as woodyasters. These are daisylike wildflowers usually having blue to purple or white ray flowers with yellow centers of disc florets. Woodyasters are native to western North America.

The longhorn beetles (Cerambycidae; also known as long-horned beetles or longicorns) are a cosmopolitan family of beetles, typically characterized by extremely long antennae, which are often as long as or longer than the beetle's body. In various members of the family, however, the antennae are quite short and such species can be difficult to distinguish from related beetle families such as Chrysomelidae.

The family is large, with over 20,000 species described, slightly more than half from the Eastern Hemisphere. Several are serious pests. The larvae, called roundheaded borers, bore into wood, where they can cause extensive damage to either living trees or untreated lumber. A number of species mimic ants, bees, and wasps, though a majority of species are cryptically colored. The rare titan beetle from northeastern South America is often considered the largest insect, with a maximum known body length of just over 16.7 centimetres (6.6 in).
