About Ptosima undecimmaculata (Herbst, 1784)
Ptosima undecimmaculata can reach a length of about 9–14 millimetres (0.35–0.55 in). Its body is cylindrical, and its head is much broader than it is long, and narrower than the pronotum. The Latin species name undecimmaculata translates to eleven spots, from the words undecimo meaning eleven and maculatus meaning stained, which originally suggested the species should have eleven spots. Usually, the actual number of spots differs from eleven, due to variation in the number, arrangement, and form of these spots. The pronotum is black, with longitudinal rugose stripes. The elytra are black with three pairs of lateral, yellowish-orange or reddish transverse markings, and frequently have preapical maculae. Occasionally, maculae may also be present on the frons and pronotal disc. This widespread species occurs across most of Europe, the Near East, and North Africa.
