other images on this page.

Males use their more highly developed antennae to seek out females (right, at rest) who release an airbourne pheromone into the night sky.This species mates readily in captivity with most pairings occuring around 3:00 am and lasting only 20-30 minutes. |
Incubation lasts as long as three weeks and humidity should be provided if ova are indoors.
The young larvae are highly gregarious, gradually becoming solitary as they grow.These larvae fashion small silk platforms on foliage, even in the first instar, leaving the platforms to feed and returning to rest. Photo courtesy of Bernhard Jost. |
There is some variation in colour among larvae, particularly in late instars.Larvae can take on a pale rosy hue or be powdery white. |
Mature larvae usually descend the host plant stems or trunks to spin a cocoon amongst leaf litter or grasses.Pupation takes place three or four days after spinup. |

The pronunciation of scientific names is
troublesome for many. The "suggestion" at the top of the page is
merely a suggestion. It is based on commonly
accepted English pronunciation of Greek names and/or some
fairly well accepted "rules" for latinized scientific names.
The suggested pronunciations, on this page and on other pages,
are primarily put forward to assist those who hear with internal
ears as they read.
There are many collectors from different countries whose
intonations and accents would be different.
