chickenman97 Posted March 26, 2019 Report Share Posted March 26, 2019 Hello Forum, I am wondering if anybody knows of a species of beetle that has an extended pupal stage of 1 month or more in captivity at room temperature? Ideally, the longer the pupal stage the better(2-6 months). I appreciate any guidance that can be given regarding this subject. Thank you, CM Quote Link to comment Share on other sites More sharing options...
Pewrune Posted March 27, 2019 Report Share Posted March 27, 2019 I think room temperature is very broad. Personally I set my AC/heater to 67F in winter, 77F in summer. And temperature affects a beetle's time to emerge. I know some Cheirotonus may take 2 months. After emergence, some species may sleep in pupa cells for a few months before active. Like Lucanus elaphus, Dynastes tityus, Goliathus regius Quote Link to comment Share on other sites More sharing options...
JKim Posted March 29, 2019 Report Share Posted March 29, 2019 Differs per species, differs per temperature, yes. They may take extra weeks when it's cold (not ready, thinking it's not spring yet). Also, if you keep them very warm, they can emerge out earlier than average time the species would take. Nothing too bad or good about it. No changes really. I used to rear Dorcus titanus castanicolor (very long time ago, in Korea) female spent about 4 months as larva, and spent 2-3 weeks for pupal stage. That isn't normal, but still emerged very large size (42mm) for the species, and lived long enough. Quote Link to comment Share on other sites More sharing options...
