Black Soldier Fly

Been learning/utilizing them for composting here in Eastern W. TN.
The forum, http://blacksoldierflyblog.com/forum/memberlist.php?mode=viewprofile&u=5049 is near unusable for me, needing pictures resized, etc.
Wondering if anybody here has knowledge on how they overwinter and what I can do to help them. Would REALLY prefer phoning. I’m 731 584 6591.
