How long for Dynastes tityus to emerge?

[ElvenAnnie]

My beetle went from larvae to pupa in mid-march(he made his pupal cell partially against the bottom of the container so I have been monitoring him) but I don't know how long he should be in there before I'm supposed to worry and I can't find a consistent answer for how long it takes for them to pupate. Please help!

It seems it depends highly in each individual from couple weeks to more than a month. Each species, each individual seems to have varying time spent in pupal cell as prepupal stage... If I remember it correctly, I think My D. tityus specimens have spent somewhere about 3 to 6 weeks after completely constructing a pupal cell until they pupated.
