Hybrid: Graellsia isabellae male x Actias sjoeqvisti female (2012).
Participation to the different pairings includes the following people: Y. Barberoux, D. Chanselme, P. Cluck, T. Dissert, P. Guivarch , F. Goussard, E. Legrand,
J. Lejeune, C. Lopez, J-P. Pagnon, J-C. Tavernier.
Different Actias and hybrid rearings and others were performed by: R. Beck, H. Evin, G. Flutsch, F. Goussard, S Kohll, H. Guyot, M. Lamour, L. Lefaix, H. Prosbt,
R. Zaun.
Several successful pairings in May 2012, two were in part fertile.
Rearing of the caterpillars was conducted without problems on Liquidambar though with some losses in the last stage, and a subsequent liquefaction of
some pupae. Male and female pupae were obtained, but for the moment only a small amount of males have emerged , females seem to remain blocked for
overwintering, or perhaps they will require the injection of a molting hormone to induce their hatching.
A very big thank you to Serge (Jevgeni Azhypa) who gave me eggs in 2011, which allowed to secure the Actias sjoeqvisti stock.

Robert Lemaitre writes, "A great and good news just arrived from Steve with the natural emergence of a female hybrid "Graellsia isabellae male x
Actias sjoeqvisti female".
Now please, can you add image and a brief comment already sent text style:
PS: unexpected natural emergence of a female hybrid without a winter diapause and without hormone injection, two months after the first emergencies of
males (picture by Steve Kohll)!
