Hi Jeff, thanks for speculating it is apreciated. I am relatively new to frogs but have had my gecko's since the early 1990's. I remember that back then even bought wax worms would often spin cocoons to pupate but the actual silk production was very low compared to that produced by the F1 generation now. I dont know when the bought ones stopped making silk, I was just curious as these guys are so different from there parents! Thanks for trying to find the answer.
