About the Clover Stem Borer
Languria mozardi, the clover stem borer, is a North American species of lizard beetle (tribe Languriini within the family Erotylidae, the pleasing fungus beetles). Two subspecies are generally included in this species: Languria mozardi mozardi Latreille, 1807
Languria mozardi occidentalis Vaurie, 1950 A third subspecies, Languria mozardi cyanipennis, established by George Crotch in 1876 as a supposedly distinct species but later included in L.mozardi, is sometimes recognized.
This is a smallish beetle even by the standards of its family, with adults being 4–9 mm long. They are mostly red in color, with black elytra, red-based brown legs, and blackish antennae; the last 1–3 ventrites of the abdomen are also blackish. The antenna "clubs" are fairly narrow and consist of the last 5 segments which gradually widen; the first of these (segment 7) is less than twice as wide as the segments of the antenna "stem". In general, the "club" segments are expanded more towards the centerline of the beetle than to the outsides.
The similar relative Languria laeta is common on the Great Plains, where L.mozardi is more rare. L. laeta is typically found on pricklypoppy (Argemone), which... Wikipedia →
