DISTRIBUTION:

Aurivillius diversus (forewing length: males: 95-98mm; females: probably larger) flies in
Zambia: Lusaka Province: Rufunsa Ranch: Lower Zambesi National Park; at elevations of 3730 feet.

The forewing apex is slightly produced and slightly pointed, not nearly as produced or pointed as in lucidus. The outer margin is slightly concave, not nearly hollowed out as much as in lucidus.

The dark transverse line is fairly even in its thickness, and it is further removed from the outer margin allowing for a wider post median/subterminal-marginal area.

The highly irregular pm line is pronounced and quite distinct in this species.

Ventral markings are very subdued n the male of this species, while in the female the ventral markings are quite distinct.

In March 2013, Philippe Darge described three new Aurivillius species from the same locale in Zambia, based on collecting done by Robert Minetti.

I do not have permission to post the images from Saturnafrica #15 (thus there are no images on this page), but hopefully the descriptions I have provided, based on my viewing of images in the publication, will help myself and others with determinations.

If you have Aurivillius specimens in your collection, and you send me images of same, with data, I will do my best to offer identifications, and will incorporate your images, credited to you, into the data base.

It might seem unlikely that three quite similar species would be flying at the same time in the exact same locale, but the images published in the journal support just that!

FLIGHT TIMES AND PREFERRED FOOD PLANTS:

Aurivillius diversus specimens have been taken in December. I suspect there are at least least two broods annually.

Larvae probably feed on Silk tree (Albizia).

ECLOSION, SCENTING AND MATING:

Females scent and attract males at night by releasing an airbourne pheromone. Males fly in a zigzag pattern into the wind to pick up the pheromone plume with their antennae.

EGGS, LARVAE AND PUPAE:

Eggs are probably translucent yellow and are probably deposited in groups of 6-10 on foodplant leaves.

Mature larvae descend tree trunks to pupate in subterranean chambers.

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.

"Aurivillius" is the last name of Dr. Per Olaf Aurivillius, a famous collector of lepidoptera and coleoptera.

The species name diversus is chosen to indicate a definite difference between this species and Aurivillius lucidus despite similarities in appearance and the same specimen type locale.
