Cerambyx cerdo Classification Family Cerambycidae > Subfamily Cerambycinae > Tribe Cerambycini > Genus Cerambyx Diagnostic Features of Larvae Mature larva. Very similar to that of C. scopolii, from which it may be distinguished as follows. Length up to 100 mm; breadth (at prothorax) up to 18 mm. Form robust. Head with genae coarsely but more evenly rugose; temples with postocular carina less marked and the elongate-oval area at the posterior end of the sclerotized part scarcely raised. Dorsal boundary of antennal foramen not raised. Front margin of head less broadly sclerotized, the pigmented band being about two-thirds as wide as the labrum is long. Front margin of frons with upper boundary at most feebly carinate (rounded in small larvae). Hypostoma with front margin and sutures pitchy. Prothorax with pronotum less coarsely sculptured. Pupa. Similar to that of C. scopolii, from which it differs as follows. Length 30-70 mm; maximum breadth 15 mm. Pronotum slightly transverse and strongly transversely striate. Mesonotum with scutellum broader and depressed. Metanotum with scutellar groove distinct, strongly striate and without basal protuberances. Abdomen with tergites two to six with oval groups of much stouter spines, which arise from ferruginous papillate bases, which are each surrounded by a pigmented disc. Adapted from Duffy (1953). Biology and Economic Importance Members of this tribe are known from various host plant families. Species of this tribe are potentially invasive outside their native range.
