Classification
Diagnostic Features of Larvae
- Mature larva. Head subrectangular, posteriorly straight. Mouthframe pitchy, genae pitchy, temples ferruginous to pitchy, rugose. Antenna with segment 3 three to four times as long as basal width and about half as long as segment 2; supplementary process very short, about one-fourth length of segment 3. Mandible pitchy rugose, bearing numerous bristly setae on basal half of outer face. Labrum transversely oval and fringed with very coarse setae. Three pairs of subcontiguous ocelli present; arranged in a straight row laterad and ventrad of antenna; lens round, convex, pigmented spot indistinct. Hypostoma pitchy anteriorly with front margin enlarged sublaterally into a pair of :flattened plate-like structures; sutures pitchy, incurved; gula abruptly raised. Maxilla with segment 3 of palp about half length of segment 2. Labial pal pi with segment 2 less than half length of segment 1. Pro thorax with posterior area of pronotum, eusternum and sternellum dull, microspiculate. Abdomen with dorsal ampullae each with two transverse furrows, nontuberculate, rather densely micro-spiculate. Tergite 9 without a sclerotized process. Anal lobes glabrous, surrounded by rather dense, short, ferruginous setae. Pleural discs indistinct. Legs with unguiculus long, slender, ferruginous, imbricately spinose. Spiracles with peritreme broadly oval, thick, pale, without marginal chambers. Length up to 60 mm; maximum breadth (at prothorax) 15.5 mm.
Pupa. Head smooth and glabrous except for small paired groups of setae at base of labrum and clypeus; vertex almost concealed from above by pronotum. Antenna with segments 3-6 produced apically into a large spine; extending to abdominal segment 5, where they are recurved and crossed beneath abdomen. Eyes feebly convex, glabrous. Pronotum subquadrate, with front margin broadly rounded; sides with a pair of short blunt conical tubercles; disc with a pair of sublateral semicircular impressions near base; bearing scattered minute setae. Mesonotum and metanotum with a few scattered minute spinules. Elytra and wings extending as far as abdominal segment 4. Abdomen with tergites 2-6 each bearing numerous short, stunted spines arranged more or less in an ellipse. Tergite 7 with numerous similar but slightly stouter spines; sides converging and broadly angled posteriorly. Tergite 8 similar, but with only a few scattered spines and a pair of paramedian, distinctly stouter spines. Tergite 9 retracted. Sternites glabrous. Legs with hind femora extending to abdominal segment 4. Functional spiracles present on abdominal segments 1-5, the sixth pair being partly closed; peritreme narrowly oval, thick, ferruginous. Length up to 44 mm; maximum breadth 12.25 mm. Adapted from Duffy (1960).
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.
