Bunaea oremansi,
flies on Sao Tomé Island, about 240 km (150 mi) west of Gabon.
As of May 2012, this species is not listed on BOLD systems, so it may have been synonymized with Bunaea alcino?.
If it is a distinct species, it is probably very similar to Bunaea alcinoe.
FLIGHT TIMES AND PREFERRED FOOD PLANTS: Specimens have been taken in October.
ECLOSION, SCENTING AND MATING:This species probably emerges at
dusk and females attract the night flying males with an airbourne
pheromone.
The pair remains coupled for a relatively short time.
Females have thinner and blacker antennae and their abdomens are
much broader and forewings are more rounded than in males.
EGGS, LARVAE AND PUPAE:Eggs are large,
round, and cream coloured, and have a deep indentation at the
micropyle.Larvae prefer fresh food and a warm, humid atmosphere.
In the final instar, airy conditions are preferred. When larvae are
disturbed they will lash their heads and front segments violently
back and forth.
Rough,
black pupae are probably formed deep (10-15 cm) underground. Under artificial
conditions pupae will emerge after being kept moist following
immersion in tepid water.
The species name, oremansi, is honourific for Oermans.
Larval Food Plants
It is hoped that this alphabetical listing followed by the common name of the anticipated foodplant will
prove useful. The list is not exhaustive. Experimenting with closely
related foodplants is worthwhile.
