Paukstadt, U. & Paukstadt, L. H. (1992): Beschreibung der Präimaginalstadien von Attacus inopinatus Jurriaanse & Lindemans 1920 von Flores, Indonesien, sowie Angaben zur Ökologie und Biologie (Lepidoptera: Saturniidae). - Entomologische Zeitschrift (Essen), 102 (12): pp. 213-220; 17 figs.

Summary: Attacus inopinatus Jurriaanse & Lindemans, 1920 is an extremely rare wild silkmoth (Lepidoptera: Saturniidae) in collections. Two entomological expeditions to the island of Flores, Eastern Lesser Sunda Islands, Indonesia were carried out by the authors to search for this species, which is closely related to Attacus atlas (Linnaeus, 1758). Several cocoons and adult specimens were collected and field observations on the life-history of A. inopinatus were made. A. inopinatus was maintained in Germany under laboratory conditions by the junior author. For the first time rearing observations on the ecology and biology are recorded and the preimaginal instars of A. inopinatus from Flores are described and figured in detail. No taxonomic conclusions are drawn in this contribution to knowledge the wild silkmoths of Indonesia. Records for which A. inopinatus (Flores) is on the wing are from January to March, May, July, and September to December. Host plants on which cocoons were found are: Avocado (Persea americana) and Kayu Rukus (a still not identified forest tree). A. inopinatus was collected at the light in altitudes between 600 m and 1820 m above sea level in the eastern Manggarai district.

Description of the pre-imaginal instars:
Egg whitish colored, length approximately 2.7 mm, width 2.3 mm and height 2.1 mm.
1st instar larva ground coloration white with two black stripes around each segment. Segments mostly with six fleshy scoli, two dorsal scoli and each side one subdorsal and one subspiracular scolus. Scoli mostly colored as body, each scolus with spines at apex. Subspiracular scoli of prothorax, subdorsal scoli of 9th abdominal segment and two long anal scoli gray with plenty of spines (compared to other scoli the number of spines is doubly). Head and thoracic legs black, prolegs and anal prolegs colored as body.
2nd instar larva ground coloration white or yellowish. Lateral orange blotches on 1st abdominal segment present. Head, thoracic legs and some subspiracular scoli black colored. Straight scoli and body covered with whitish powder (wax).
3rd instar larva ground coloration greenish. Orange blotches only on 1st abdominal segment present. Dorsal and subdorsal scoli of meso- and metathorax yellow colored with white tip. Some subspiracular scoli black colored.
4th instar larva waxy powder reduced. Anal scoli reduced, dorsal and subdorsal scoli of meso- and metathorax yellow colored with white tip. Anal prolegs black, ventrally with a pink line.
5th instar larva thoracic scoli and subdorsal scoli of 8th abdominal segment reduced. Dorsal and subdorsal scoli of meso- and metathorax yellow. Scoli on meso- and metathorax and anal scoli (partly?) transformed to defensive glands. Waxy powder much reduced. Patch on the outside of each hindmost proleg blackbrown, ventral orange bordered.
6th instar larva ground coloration lateral and ventral green, dorsal pale green. Defensive glands on meso- and metathorax orange colored, subspiracular scoli blue, all other scoli colored as body. Spiracles white, brown bordered. The patch on the outside of each anal proleg is fully dark purple, ventral rose bordered.
Pupa ground coloration redbrown, length approximately 45-55 mm. Length and largest width of the antennal covers in the male pupa 25/13 mm and in the female pupa 21/7 mm.
