Synonyms and other taxonomic changes
Leichenum variegatum and numerous other synonyms listed in U. of Florida article cited below
the only species in this genus in North America listed at
adult body length about 5 mm
larva length to 12 mm
Adult: The body appears gray, although actually mottled with black, gray, brown, and whitish spatula-shaped, scale-like setae. This mottling is sometimes variable, depending on the number of these scale-like setae that have been rubbed off. The eyes are globose and slightly emarginated, with erect setae between facets. The setae located between the facets are hypothesized to protect the eyes from damage when they burrow into the sand (Medvedev 1973). The antennae are short with a clearly defined 4-segmented club on the apical half. [text copied from U. of Florida page]

Larva: body orange, hairless, resembling a small wireworm (Elateridae larva); see detailed description of each larval body section at U. of Florida
first found in United States in Alabama in 1906 and Florida in 1920 (apparently introduced from its presumed native land, Madagascar); now known in coastal areas from Mississipi to North Carolina
also occurs in many countries throughout the Old World
beaches, dry dunes, lake and river shorelines, and other open sandy habitats; adults usually hide under small piles of leaf litter, boards, or pieces of wood, and are attracted to light
recorded from March to November, but probably occurs all year
adults and larvae probably feed on roots of plants

Digging Darkling Beetle (Ammodonus fossor) is not so mottled; its elytra have distinct linear bands with pale spots, and its pronotum is uniformly grayish-brown
