Pachytodes cerambyciformis Classification Family Cerambycidae > Subfamily Lepturinae > Tribe Lepturini > Genus Pachytodes Diagnostic Features of Larvae Mature larva. Rather similar to those of Strangalia species, from which it differs as follows. Length up to 19 mm; maximum breadth (at prothorax) 4 mm. Head with antenna with third segment cylindrical, elongate (at least twice as long as basal diameter); second segment with supplementary process conical, elongate, extending at least as far as apex of third segment. Mandible without an oblique striated plate on cutting edge. Ocellus with lens slightly protuberant anteriorly; pigmented spot rather indistinct. Hypostoma about four and one-half times as wide as median length; sutures almost straight; anterior margin ferruginous. Gular sutures very slightly raised. Maxillary palpi with third segment elongate, slightly longer than second. Labial palpi separated by slightly more than their width. Prothorax with eusternum very feebly rugose, reticulate, shining and with a few scattered setae; never spiculate or pubescent. Abdomen with ampullae on segments one to seven, the seventh being very small, feebly tuberculate, but distinctly spiculate. Legs with unguiculus very long and slender; ventral margin concave for about apical two-thirds; basal third parallel-sided. Spiracles with marginal chambers forming a characteristic crescent. Pupa. Rather similar to those of Strangalia species, but differs in the following respects. Length 7-12 mm; maximum breadth 3.25 mm. Head with vertex bearing five or six pairs of short setae. Pronotum strongly bent downward so that it is almost at right angles to the meso- and metanotum; rather densely covered with scattered ferruginous setae. Metanotum with a pair of raised oval tuberculate areas, each bearing numerous setae. Abdomen with setae on all tergites Jong, pale and slender. Ninth sternite with short, stout urogomphi. Legs with hind femora very long, their apices being considerably higher than general dorsal level of body; bind tarsi long, extending as far as seventh abdominal segment. Adapted from Duffy (1953).
