From Q. How long before they emerge as moths?
"However, in order to have the moth continue to develop and not enter diapause, this way eclosing (emerging) 4 weeks after pupating, you will need to expose the larva to 13-15 hours of daylight, mimicking early season photoperiod (day length). This can be done with UVB light setups if normal day needs to be extended."
So, if you want them to go into diapause (therefore not emerge as moths for several months as opposed to having them eclose in about 4 weeks) you need to "mimic" nature and adjust natural light during their larval stage.
In the winter, this is easy to do because our days are shorter anyway. You can leave them in a room where they are exposed to current daylight cycles, no additional lights - UVB or other. If you have a shade in the room you can even close it about an hour before the sun goes down to assure diapause. About a week or two after they pupate you can put them into a plastic, covered container and place into the crisper section of your fridge. This will continue to inhibit their emergence, but be SURE to wait the 2 weeks. If you place them in cold before fully pupated you can kill it.
The UVB light is more for extending their day length exposure. So if you want them to eclose within a month or so after they pupate you will need to use UVB lights to extend the day by a few hours (mimicking summer day length)
I hope this clarifies it for you. let me know if you have other questions!
