Glenea giraffa
Classification
Diagnostic Features of Larvae
- Mature larva. Length up to 24 mm; maximum breadth (at prothorax) 4.1 mm. Head moderately depressed, with sides subparallel (maximum head-width 3.2 mm), feebly constricted before middle and broadly rounded at base; antennal foramen closed posteriorly. Mouthframe moderately sclerotized, ferruginous, the ferruginous band much narrower than length of clypeus; frons with a transverse row of ten to twelve setae; six epistomal setae present; genae strongly shouldered and ferruginous. One pair of ocelli present; lens round, strongly convex; pigmented spot distinct. Clypeus bearing two to six short lateral setae. Hypostoma slightly convex, smooth, testaceous, with front and hind margins ferruginous; sutures ferruginous and incurved. Gula indistinct, with two widely separated setae on each side. Antenna 2-segmented; segment 2 quadrate and bearing a conical hyaline process. Maxillary palp with segment 3 conical, slightly shorter than segment 2; palpifer elongate, subparallel-sided. Mentum not distinct from submentum. Prothorax obliquely slanting anteriorly; posterior area of pronotum covered with coarse individually distinguishable asperities which become gradually smaller towards posterior margin; sublateral impressions rather shallow, transversely oval. Presternum with scattered fine setae; posterior area of eusternum and anterior area of sternellum each with a transverse band of asperities. Abdomen with each dorsal ampulla with two curved transverse furrows, a distinct median longitudinal furrow and bearing numerous scattered, short, blunt asperities. Segment 9 unarmed. Epipleurum protuberant on all segments. Pleural tubercle oval, bearing about four pale setae; sclerotized pits absent. Anus rather strongly protuberant, trilobate. Legs absent. Spiracles with peritreme very pale, rather narrowly oval and moderately thick. Adapted from Duffy (1957).
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.
