Fodina Guenée

Type species: oriolus Guenée, Bangladesh.

The species are typically moderately robust, and the wings strikingly marked. The forewings are dark brown with an oblique white or paler brown bar dividing them from the centre of the costa to the tornus, and with a finely banded pale brown to whitish marginal zone. In some species the central band continues basad along the costa and also there may be an additional loop or semicircle at its tornal end. The hindwings are usually yellow with a dark brown border that is broadest around the apex. The male antennae are filiform. The lower clypeofrons is unscaled.

In the male abdomen, the eighth segment is not modified or only slightly so. The genitalia of the type species have the apical part of the valve divided into two digitate processes that cross over each other. The juxta is massive, arising from the valve bases to expand into a winged structure that terminates in a long, upcurved horn. In the only Bornean species, the uncus has a scaphial structure similar to that in
Macrobarasa Hampson (Holloway, 2003) or, less close, the Scoliopterygini (p. 213). The valves are narrow, weakly divided distally, and the juxta is much weaker, with tapering processes directed dorsally from where its margin fuses on each side with the valve sacculus. The vinculum is closely associated with valve bases in both species, and there is no saccus.

The female of the type species has the ostium within the meeting point of the posterior corners of the seventh tergite and the bifurcate apex of the reduced seventh sternite. The ductus is very short and the corpus bursae is elongate, sausage-like, with general scobination and corrugation near the basal two-thirds up to a large, bluntly and asymmetrically triangular signum.

The genus is found (Poole, 1989) throughout the Old World tropics to Australia and as far east as New Caledonia (but not recorded there by Holloway (1979); material in USNM). It is possibly more diverse in areas with a marked dry season; there are many species described from Madagascar.

The larvae of two Indian species have been described:
F. stola Guenée (Gardner, 1941, 1948a; Bell, MS); F. pallula Guenée (Gardner, 1948a; Sevastopulo, 1944). They have a full complement of prolegs that are approximately equal in size. The crochets are heteroideous, a short row at each end of the mesoseries being abruptly smaller. The colour in stola is very variable, the head yellow to pale brown or reddish. The body is black and yellow (Bell referred to a watery blue ground virtually obscured by these colours), the black varying in extent, from four thick transverse marks on each segment to being more continuous, restricting the yellow to entire or broken dorsolateral bands, often wider on A8, and distinct spiracular bands. The spiracles are black. In pallula the colour is mostly pale green with paradorsal white lines and some dorsal white spots. There are black spots on T1 and A2 and also on A8.

Pupation is in the soil in a thin cocoon. The pupa lacks a bloom.

The egg in
stola is a low dome, pearly yellow white, with 34-38 ridges running up from the base, though only about 10 of these extend up to the micropyle, the rest terminating at a variable distance from it.

Host records are all from the Apocynaceae:
Holarrhena, Tabernaemontana, Vallaris (see also Common, 1990, and Robinson et al., 2001).
