Eburia quadrigeminata
Classification
Diagnostic Features of Larvae
- Mature larva. Length up to 25 mm; maximum breadth (at prothorax) 7 mm. Form rather robust, compressed posteriorly. Head quadrate, with sides almost straight and parallel-sided (maximum head-width 4.2 mm). Gena moderately shouldered, smooth, narrowly testaceous and bearing a few long, fine setae. Front margin of head rather indistinctly ferruginous. Front margin of frons evenly rounded. Antennal foramen with upper boundary not raised or produced. Mouthframe entirely sclerotized beneath antennae. Antenna slender, with second and third segments at least twice as long as broad; third segment cylindrical, about half length of second; supplementary process minute. Clypeus very short. Labrum suborbicular, thick, fleshy, with front margin densely setose. Mandible short, stout; basal part ferruginous, two-thirds length of pitchy, apical part. Ocellus subcontiguous with base of antenna; lens large, round, white; pigmented spot very indistinct and partly surrounded by shouldered gena. Hypostoma with front margin longitudinally rugose, testaceous. Gular sutures protuberant, parallel. Maxilla with third segment of palp shorter than second; process of palpifer minute. Prothorax quadrangular, with four pale yellow, sclerotized plates; pronotum slightly transverse; anterior part bearing scattered fine setae; posterior part alutaceously striate and with scattered lenticular pits; median cleavage line deeply impressed. Sternum wrinkled, with scattered setae, except for two glabrous, smooth patches on eusternum. Abdomen compressed laterally; dorsal ampullae alutaceous, shining, with two lateral and two transverse grooves. Anal lobes rugose. Pleural discs wrinkled, indistinct. Legs four-segmented, moderately long; unguiculus flagelliform, feebly sclerotized and imbricately spinose. Spiracles with peritreme thin and pale. Adapted from Duffy (1953).
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.
