Cephonodes picus Cramer
Sphinx picus Cramer, 1777, Uitl. Kapell., 2: 38.
Cephonodes picus Cramer; Rothschild & Jordan, 1903: 469.
Diagnosis. This species can be distinguished from C. hylas
yet recorded from Borneo, by the strong spine at the apex of the foretibia.
Otherwise the two species are very similar.
Geographical range. India to Queensland and New Guinea.
Habitat preference. All recent Bornean material has been taken in coastal
localities in Brunei, in populated areas.
Biology. Two Brunei specimens were recorded from Gardenia (Rubiaceae)
(Harman, 1981). The larva is entirely green with a bluish white dorsal
line and white dorsolateral ones, tending to be more glaucous above the
latter (Dupont & Roepke, 1941). Bell & Scott (1937) stated the
larva to resemble that of the type species. In hylas there is also a dark
form with T1 ochreous orange, the rest of the body white with a broad
black or bluish dorsal stripe, a white or pink subdorsal stripe with a
broad black stripe below it. The flanks are illustrated as yellowish.
Recorded host-plants (Bell & Scott, 1937; Dupont & Roepke, 1941;
Holloway, 1983; CIE records) are: Jasminum (Oleaceae); Adina, Coffea,
Gardenia, Guettarda, Morinda, Pavetta, Randia, Tarema (Rubiaceae);
