Chlorophorus carinatus
Classification
Diagnostic Features of Larvae
- Mature larva. Length up to 21 mm; maximum breadth (at prothorax) 5.2 mm. Head subtrapezoidal, with sides almost straight, slightly diverging posteriorly (maximum head-width 3.2 mm). Gena somewhat shouldered, pale, smooth, bearing several fine setae. Frons smooth, pale testaceous, with a transverse row of fine setae near front margin. Mouthframe rather strongly sclerotized, ferruginous; sclerotization complete beneath antenna and enclosing ocellus. Antenna with segment 3 cylindrical, about four times as long as broad and slightly more than half length of segment 2; supplementary process very short. Labrum semicircular, fringed with fine silky setae. One pair of ocelli present; lens round, protuberant: pigmented spot rather indistinct. Hypostoma testaceous, with front margin broadly ferruginous and rugose (mainly transversely) and bearing a few fine setae; sutures slightly curved, ferruginous. Gula rather broad, distinctly raised. Maxilla with segment 3 of palp as long as segment 2; dorso-external process of palpifer much shorter than segment 3 of palp. Labial palpi with segments 1 and 2 equal in length. Prothorax orange-testaceous anteriorly; rather coarsely longitudinally striate posteriorly; median cleavage line deeply impressed. Eusternum with a pair of paramedian, oval, glabrous, shining areas. Abdomen with dorsal ampullae extremely finely micro-granulate. Anal lobes sparsely setose. Pleural discs indistinct. Legs minute, about as long as segment 3 of maxillary palp. Spiracles with peritreme rather broadly oval, thin and pale. Adapted from Duffy (1957).
Biology and Economic Importance
- Members of this tribe are known from various host plant families and several genera (e.g., Chlorophorus, Xylotrechus) are considered economically important. Species of this tribe are potentially invasive outside their native range. More information is available at the CAPS website.
