Hippotion rosetta Swinhoe
Chaerocampa rosetta Swinhoe, 1892, Cat. Lep. Het. Mus. Oxon., p. 16.
Hippotion depictum Dupont & Roepke, 1941: 70, syn. n.
Diagnosis. See Hippotion boerhaviae
Taxonomic notes. See previous species. The record of H. boerhaviae from
Cocos-Keeling I. (Holloway, 1983) was a misidentification of rosetta.
Geographical range. Indo-Australian tropics to Solomons.
Habitat preference. This species is common in lowland open habitats, but
has also been taken at 2600m on G. Kinabalu.
Biology. The larva was described by Dupont & Roepke (1941); these
authors consider that Bell & Scott (1937) also described this species
under boerhaviae. The larvae are green or greyish brown. Both forms have a
configuration of ocelli as in boerhaviae, perhaps slightly smaller
overall. That on A1 is black with white spots circled by a yellow and
black ring. Those on other segments are brown, ringed black and yellowish
white. The horn is short, yellowish green with a black tip in the green
form, and unicolorous grey-brown in the brown form.
The host-plant was Borreria (Rubiaceae); the larvae would not feed on
Oldenlandia, the Javan host of boerhaviae. Host-plants recorded in the
literature (see boerhaviae above) could be referable to either species.
