Gracilia minuta Classification Family Cerambycidae > Subfamily Cerambycinae > Tribe Graciliini > Genus Gracilia Diagnostic Features of Larvae Mature larva. Very similar to those of Molorchus species, from which it differs as follows. Form much more slender. Head with a distinct ocellar lens laterad and slightly ventrad of antenna; pigmented spot black, very distinct. Prothorax with pronotum more closely and evenly longitudinally striate. Abdomen with ampullae more strongly protuberant. Epipleura of eighth and ninth segments much less strongly protuberant. Legs present but very minute. Pupa. Length 3.5-7 mm.; maximum breadth 1.3 mm. Head with vertex visible from above, smooth and with about six papillae (each with a long, fine, subapical seta) on each side of disc; front with two or three minute setae near base of each antenna; clypeus with a transverse impression at base. Antennae extending as far as fourth abdominal segment, where they are strongly recurved to terminate near fore coxae. Eyes moderately convex, with a stout seta near mesal margin. Labrum triangular, glabrous. Pronotum bearing numerous long pale papillae (each with a long, fine basal seta) along front and lateral margins and two groups of fine setae near base. Mesonotum smooth and usually glabrous; scutellum moderately protuberant. Metanotum smooth, but sometimes with two or three minute setae. Elytra and wings extending to third abdominal segment. Abdomen with tergites one to six, each with a transverse row of from four to six short papillae (each with a fine seta). Ninth segments retracted into eighth and not visible from above. Sternites glabrous or almost so. Pleura slightly protuberant, each with fine, paired setae. Legs with hind femora extending as far as fourth abdominal segment, and lying almost parallel to longitudinal axis of body. Functional spiracles present on first seven abdominal segments; peritreme round, very thin, and inconspicuous, but slightly raised above general level of cuticle. Adapted from Duffy (1953). Biology and Economic Importance Biology unknown for members of this tribe. Species of this tribe are potentially invasive outside their native range.
