Eucrossus villicornis Classification Family Cerambycidae > Subfamily Cerambycinae > Tribe Hesperophanini > Genus Eucrossus Diagnostic Features of Larvae Larva. Form elongate, robust; integument thin, dull, rather thickly covered with short golden-yellow hairs. Head subtrapezoidal, somewhat depressed; mouth-frame darkly chitinized; epistoma suddenly emarginate in middle; labrum suborbicular, the disc glabrous; mandible black at tip, basal half lighter and shorter than apical, latter with a slight impression on outer face; one pair of large ocelli enclosed by the strongly shouldered and tuberculate gena; genal setae short, dense; antennae salient, first joint shorter than second, a little longer than third; last joint of maxillary palpi shorter than others, shorter than last labial; process of palpifer distinct, as well as the process on first maxillary joint; hypostoma smooth; gula very short, wider than long; no subfossal spine. Prothorax rectangular, densely and coarsely haired at sides and across anterior margin of pronotum; posterior area of pronotum shining and finely alutaceous, projecting forward in middle, hind margin velvety pubescent, no median suture; eusternal spots large, shining, separated by a fine, dull granulate band. Mesonotum and metanotum dull, very finely velvety pubescent; extremity of sternellar fold distinct, passing beyond spiracles. Legs four-jointed. Ampullae broad, dull, very finely granulate, dorsal bearing two lateral and two transverse impressions. Pleural discs very large and dull granulate, bearing a very deep pore, distinct on five segments, largest on third; spiracles broadly oval, peritreme very thin. Pupa. Disc of prothorax bearing scattered, acute, chitinous points, projecting anteriorly; posterior portion of metanotum and each abdominal tergum also bearing much stronger conical chitinous points, projecting posteriorly, arranged on the anterior segments in transverse rows, and the middle points often set on a chitinized disc; two small curved spines on last tergum. Adapted from Craighead (1923). Biology and Economic Importance Members of this tribe are known from various host plant families and at least one genus (Trichoferus) is considered economically important. Species of this tribe are potentially invasive outside their native range. More information is available at the CAPS website. Selected References to Larvae Specimens Craighead, 1923
