Subfamily: CassidinaeGenus: Cephaloleia
SUMMARY
EGG
Cephaloleia dorsalis eggs are are about 2.5 mm long and are laid singly or in clusters or two or more on host plant petioles, the surface of bracts, or the inner surface of inflorescence bracts and are covered with frass. Eggs hatch in 10 to 14 days. The larvae have two instars the first lasting 10 to 18 days and the second 36 to 48 days. The pupal stage lasts from 14 to 20 days. Adults live about 157 days.
LARVA
From García-Robledo et al. (2010): Color when live pale yellowish, margins translucent; venter pale yellowish. Color when dead dirty-brown with paler margins. Total length 6.4-6.7 mm (n=3); width 4.3-4.4 mm.
Dorsum. Prothorax surface of central elevation micropustulate; with two diagonal carinae laterally extending to lateral margin, carinae wide at base, narrowing apically to sharp point; surface laterally punctate. Meso- and metathorax with base elevated, sloping back to apex, narrowing laterally into sharp point; punctate laterally. Abdominal tergites 1-6 wider than long, decreasing in width; base elevated, sloping back to apex, ending in sharp point; punctate laterally. Tergites 7-9 with two diagonal carinae on each side which extend to lateral margin. Spiracles just off central elevation, with margins darkened.
Venter. Surface of expansions punctate, rugose-striate. Head surface rugose-punctate; labrum with surface alutaceous, without setae; clypeus with fringe of long setae at apex, with four setae on apical ½, surface alutaceous; mandibles tridentate; maxillary palps with 2 palpomeres and short, robust setae at apex; maxilla robust, clavate, with fringe of long setae at apex; labium densely setose. Antenna with antennomere 1 short, robust; 2 narrower than 1, transverse; 3 elongate, cylindrical, narrower than 2, with fringe of short setae at apex. Pro- and mesothorax wider than long; slightly depressed in middle; surface rugose-striate. Metathorax longer than others; depressed in middle; with suture along apical margin. Abdominal sternites 1-8 wider than long; decreasing in width; laterally with curved sulcus dividing the sternite into thirds; sterna 9-10 fused, rounded at apex. Leg: femur short, robust; tibiotarsus subconical, with a strong claw and eight setae at apex.
PUPA
Larvae pupate inside the second instar larval exuviae. Pupa is yellow, covered with transparent ornaments (see figure).
ADULT
Head, antennae, and pronotum black; elytra yellow with black sutural spot and vitta; legs yellow. Head: vertex densely punctate; faint medial carina; keel between antennae; frons not projecting. Antenna: filiform; more than ½ body length; antennomere 1 thickened, subequal in length to 2; 2 cylindrical; 3 cylindrical, as long as 1 and 2 combined; 4-10 cylindrical, decreasing in length; 11 longer than preceding, rounded at apex; 3-11 setose. Pronotum: black; slightly wider than long; arched; disc strongly punctate; side strongly margined; anterior angle slightly produced, rounded; posterior angle angulate; pronotal length 0.7-1.0 mm (n=10); pronotal width 1.1-1.6 mm. Scutellum: pentagonal; smooth. Elytron: oblong; moderately convex; strongly punctate-striate; margined laterally; lateral and apical margins smooth; apices cojointly rounded; puncture rows lightly impressed; puncture rows complete; sutural vitta orbicular at base, to puncture row 3, narrows to only suture, darkened after middle; last segment of pygidium u-shaped in male, ovoid in female; elytral length 3.3-4.0 mm; elytral width 1.9-2.3 mm. Venter: pro-, meso-, and metasterna red and smooth in middle, dark and punctate laterally; abdominal sterna 1 and 2 fused in middle; abdomen setose. Leg: dark; tibia with fringe of setae at apex; femur punctate on top. Total length: 4.4-5.4 mm; females are larger than males.
