|
||
Two scales appear on the dorsal base of Ant. I–II during 2nd Inst.; there are no scales on Ant. III–IV or on the ventral side of any segment. The distribution of scales remains unchanged during 3rd Inst. and expands minimally at 4th Inst. By 5th Inst. scales cover all the dorsal surface of Ant. I, the basal half of Ant. II, and the basal fifth of Ant. III. In adults, two thirds of the dorsal surface and somewhat less than half of the ventral surface of Ant. II are covered with scales; Ant. III has scales dorsally on the basal fourth and ventrally on the basal fifth; scales are absent from Ant. IV and the ventral surface of Ant. I.

|

The first instar has three ciliate setae and is devoid of botriothrica (Fig. 13). The number of setae and sensilla increases during 2nd -3rd Inst. (Figs 14, 15), but no botriothrica appear until 4th Inst. (Fig. 16). A second botriothricum is added during 5th Inst. (Fig. 18). Adults appear to be dimorphic in the number of botriothrica: males have four, females three (Figs 19, 20).

|

The first instar (Fig. 9) has one botriothricum and some ciliate setae, but no other sensilla. At 2nd Inst. (Fig. 10) the number of ciliate setae increases, and a thin-walled, tapered sensillum is added. A second botriothricum appears at 3rd Inst. (Fig. 11). The third botriothricum is added at 4th Inst. (Fig. 12). In subsequent instars the relative distance between the three botriothrica changes, but only ciliate setae and sensilla are added. Short, conic setae associated with the botriothrica appear by 5th Inst. (arrows in Fig. 17), increasing numerically during subsequent instars (Fig. 21).

The pro- and mesothoracic legs lack scales during 2nd Inst., but there is a single scale, distally on the external side of the metafemur and metatibiotarsus. Scales appear on the meso- and metacoxae in 3rd Inst. By 4th Inst. there are scales on all segments of all legs, but on the first two pairs the scales do not cover all surface.

; the transformation of a1 into a microchaeta, which together with a2 and p3 are displaced close to m2, becoming precursors of the fan setae of the botriothrical complex; and the relocation of m4 closer to a5. At 3rd Inst. the chaetotaxy of area M is completed with the addition of two ciliate microchaetae (Fig. 71). The lateral botriothrical complex is unstable at this instar. All specimens add seta c3 between pm6 and emp, but three additional setae are asymmetrically present, in different combinations, in three of seven specimens examined. The chaetotaxy of the a5 complex remains unstable at 4th Inst.: three specimens have six setae, two have five setae, one has three setae on one side, and one has seven setae on one side. In addition, am6 is a short truncate macrochaeta in two specimens. By 5th Inst. the chaetotaxy is identical to the adult (Fig. 72): all setae in the botriothrical complexes are fan-shaped; am6 is a macrochaeta; and p
