Hybrid Pairings:Dominique writes, "Some of these pairings have, of course, no chance of producing hybrid moths or even caterpillars because of genetic barriers. Others, surprisingly produce caterpillars (Graellsia x Eudia), but not homozygot ones. "Still others, perhaps genetically potentially fertile, are highly non-probable because mechanical barriers such as penis waist/length (for example luna male with regards to Graellsia), spur (for example Argema with regards to Graellsia male) and so on provide insurmountable difficulties. Some pairings are difficult to obtain without a calling female, others are very easy because of male activity such as that of Ceranchia and Eudia males that pair with every thing, even other males or inert objects."

"Successful" Pairings:All of the following is from Dominique Adès. The first section shows exemplars from interspecific pairings done from 1991 to 1993 between two Actias species: luna Linnaeus male (L) on the one hand, truncatipennis Sonthonnax female (T) on the other hand (See publication in “Bulletin de la Société Sciences Nat” n° 78 in June 1993, p 15-24, 28 coloured photographs in 9 pages (http://www.insects.demon.co.uk/revuebullsn.html)). An aberration sometimes appears in homospecific Mexican “Normal” truncatipennis stock rearings with then systematically a 25% yield with regards to the eggs. This aberration is recessive, agreeing with Mendel’s first law and doesn’t seem to have been described (from our knowledge) for wild truncatipennis moths. It also appears in luna x truncatipennis hybrids in such a ratio that agrees with Mendel’s law. All abnormal moths are perfectly fertile, set up and fly perfectly. All F1 to F6 hybridizations show that luna and truncatipennis are obviously regional variations with geographical isolation and not two different Actias species. This stable and viable aberration (morph) shows moreover the easiness of those actiens evolution capabilities. Listing of done hybrids:
