Dorcadion pusillum is a species of longhorn beetle of the subfamily Lamiinae.

Longhorn beetle Family of beetles characterized by long antennae

The longhorn beetles 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 the Chrysomelidae. The family is large, with over 26,000 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 cm (6.6 in). The scientific name of this beetle family goes back to a figure from Greek mythology: after an argument with nymphs, the shepherd Cerambus was transformed into a large beetle with horns.

Lamiinae Subfamily of beetles

Lamiinae, commonly called flat-faced longhorns, are a subfamily of the longhorn beetle family (Cerambycidae). The subfamily includes over 750 genera, rivaled in diversity within the family only by the subfamily Cerambycinae.

Description

The length of the adults is 8–10 millimetres (0.31–0.39 in). The first segment of the antennae and legs is reddish brown. The back and shoulder are striped and dull, and the color is either gray or pale brown. The suture and manifold are bright white. There is a black stripe on the bugs spine. The elytron is with dark round spots.

Antenna (biology) appendages used for sensing in arthropods

Antennae, sometimes referred to as "feelers", are paired appendages used for sensing in arthropods.

In anatomy, a suture is a fairly rigid joint between two or more hard elements of an organism, with or without significant overlap of the elements.

Manifold topological space that at each point resembles Euclidean space

In mathematics, a manifold is a topological space that locally resembles Euclidean space near each point. More precisely, each point of an n-dimensional manifold has a neighborhood that is homeomorphic to the Euclidean space of dimension n. In this more precise terminology, a manifold is referred to as an n-manifold.

<i>Hordeum pusillum</i> species of plant

Hordeum pusillum, the little barley, is a diploid annual grass native to the United States, which arrived via multiple long-distance dispersals of a southern South American species of Hordeum about one million years ago. Its closest relatives are therefore not the other North American taxa like meadow barley or foxtail barley, but rather Hordeum species of the pampas of central Argentina and Uruguay. It is less closely related to the Old World domesticated barley, from which it diverged about 12 million years ago.
