About the laying of Agrius convolvuli
Hello,
I have tried several times to obtain eggs of this sphinx from females captured at the end of August, September in Belgium, without success. I suppose that these are specimens that will migrate to the south. Is it possible that these specimens (or their eggs) only become fertile once they arrive at their destination?
Has anyone already obtained eggs +/- under the same latitude or further north at the end of summer?
Regards
Philippe
