Stictoleptura scutellata

Classification Diagnostic Features of Larvae
  • Mature larva. Similar to that of Stictoleptura quadrifasciata, from which it differs as follows. Head with genae with a deep transverse furrow immediately in front of ocellus. Antenna as in Rutpela maculata. Labrum with a semicircular transverse impression behind front margin, which is densely setose. Hypostoma with anterior margin pitchy. Labial palpi separated by about twice their width. Prothorax with eusternum without spicules or pubescence, but surface coarsely rugose and bearing a few scattered setae. Abdomen with ampullae present on segments one to seven.

    Pupa. Similar to those of Leptura species, from which it differs as follows. Length 14-19 mm; maximum breadth 6.5 mm. Head with vertex bearing a group of three to five long, stout setae above each eye; front with about nine to eleven long, stout setae opposite base of each antenna and with a deep transverse impression above. Antennae extending as far as first or second abdominal segment, where they are recurved to terminate near middle of hind tibiae or apex of mid tibiae. Eyes with a single large seta on upper margin. Labrum glabrous; base with a deep transverse impression. Pronotum quadrate to very slightly elongate, with hind angles almost right-angled; front margin with a pair of paramedian protuberances, each bearing four to six short, stout setae; hind margin with a transverse row (interrupted medially) of stout setae; remainder of pronotum with widely scattered setae. Abdomen with tergites one to six each bearing paired oval papillate protuberances. Seventh tergum elongate, with a transverse row of shorter setae near hind margin. Eighth tergum similar but shorter. Ninth tergum short, with sides converging posteriorly, practically glabrous and terminating in a pair of slender, excurved urogomphi, which are directed downward. Sternites three to seven sometimes with minute setae. Eighth sternite glabrous. Ninth sternite with three or four pairs of short setae. Legs with a row of small setae (above which are a few finer setae) on outer face of each femur; tarsi as long as tibiae. Functional spiracles with peritreme very broadly oval, thin and slightly raised above general level of cuticle. Adapted from Duffy (1953).
