GoHeracross Posted January 11, 2022 Report Share Posted January 11, 2022 I’ve noticed a lot of beetles live only a few months as full grown adults. Which ones tend to have the longest lifespan as adults? Thanks! Quote Link to comment Share on other sites More sharing options...
Goliathus Posted January 11, 2022 Report Share Posted January 11, 2022 Some adult tenebrionids can live for an exceptionally long time. Some adult lucanids can survive for at least several years. Quote Link to comment Share on other sites More sharing options...
Acro Posted January 11, 2022 Report Share Posted January 11, 2022 As adults, I believe Phileurus truncatus can live about 2 years. Gymnetis Thula can live about 1 year or longer if I remember correctly. Quote Link to comment Share on other sites More sharing options...
Goliathus Posted January 11, 2022 Report Share Posted January 11, 2022 I haven't been able to track down any references, but a colleague once told me that certain darklings had been recorded as living for up to 20 years as adults. He might have been talking about some of the species that have been tagged and monitored in the Namib Desert, along the southwest coast of Africa.

jake7917 Posted January 11, 2022 Report Share Posted January 11, 2022 Although not really available captively bred yet, or as larvae, Blue Feigning Death beetles live for years as adults. Quote Link to comment Share on other sites More sharing options...
Kati Lee Posted January 12, 2022 Report Share Posted January 12, 2022 I have gymnetis Thula and dorcus titanus beetles because they’re both supposed to be long lived. The stags hibernate to live that long, my gymnetis have not hibernate but move pretty slow this time of year. They’re all about 5-8 months old now and I hope will live longer.

Species Lucanus are among the shortest-lived adult stags, maybe you're thinking of maximum lifespan from egg? Quote Link to comment Share on other sites More sharing options...

I've heard some crazy longevity statements on darklings including Asbolus and Eleodes but I've kept quite a few from eclosion and 2-5 is realistic. Anything past 6 is likely entirely imagined. Phileurus 18-30 months, Dynastes tityus up to 12, Dorcus ~12 months Quote Link to comment Share on other sites More sharing options...
