I added the pics of Abe's senescence to the tread, check those out for some comparison. I don't know how long I "typically" had one, it so depends on how old they are when you get them (no sarcasm intended there…). I think they naturally die off in the late spring if they hatched out the summer before. I never really start worrying until I see autophagia setting in. At least since you have a male, you get to see him until the end. Female aculeatus brood for about 6 weeks then die. The whole time you hardly get to see them, then a flurry of babies and everyone dies. My girls like males better, they don't think loosing them is as hard.
