Diagnosis.
There is some sexual dimorphism, males being larger than females with paler
brown basal halves to the wings. The forewing has a slight, double submarginal
fascia, and centrally the fine, dark brown antemedial and postmedial fasciae
form an approximated triangle round the faintly darker reniform, except the
postmedial curves round basad over its anterior third and the fasciae converge
but do not quite meet at the dorsum forming more of a trapezium.
Geographical
range. Indo-Australian tropics to Queensland, Bismarcks and New
Caledonia.
Habitat
preference. Most records have been from disturbed forest or areas of
cultivation from the coast of Brunei to the slopes of G. Kinabalu (Kundasan and
Bundu Tuhan; 1050m and 1200m).
Biology.
No information on early stages has been located, but the Australasian O.
parcemacula Lucas,
which shares some features of the male genitalia, particularly uncus structure,
with trapezium,
has been reared from Loranthaceae and Melaleuca (Myrtaceae) (Holloway, 1979; Common, 1990).
The
adult of trapezium pierces fruit (Wu, 1981; Bänziger, 1982).
