Darkling beetle rose from the dead

Walking on a trail one year ago I happened to notice a darkling beetle scurrying on the ground, scooped it up in a Tupperware, and brought it home to put it in an empty enclosure I had available with some substrate. A week or so later it died, not sure why, I figured it was just at the end of its life cycle. But I ended up just leaving it there in the enclosure.

One year later, today, I noticed a new beetle in the enclosure. I thought, "huh, I guess she laid some eggs before she died, and one must have survived all on its own and became an adult". I checked the enclosure more thoroughly and found that the beetle that I thought was dead, who was still in the same place, upside down, was moving. I flipped her over and she started walking and eating. What the . I am shook. What is happening. Did it contract a zombie fungus or something? There's no way a beetle can survive for a whole year on its back motionless, right? Was it hibernating?? If so why?? And why wake up now in August???

 
For what it's worth (and that may not be much according to recent reports), Bard asserts that 2year+ diapause has been observed in Tenebs. This assertion is ostensibly supported with the following cites:

  • "Occurrence of prolonged diapause in ethm-iid moths and Teneb-rionidae (Insecta: Coleoptera)" by V. K. Gupta and J. K. Srivastava. Bibliography of Agriculture, vol. 74, no. 1, pp. 193-194, 1974.
  • "Carpophilus hemipterus: A facultative parasite of laboratory animals" by J. E. Flynn and J. F. Anderson. Flynn's Parasites of Laboratory Animals, pp. 349-351, 1975.

Wow! That is amazing! I'm assuming what Anacimas said is what happened. A long diapause. I have seen blue death feigning beetles when kept at very cool temperatures during the winter go many months with eating extremely little or none. Can you take a picture of the species?

Wow, interesting information! Thanks for sharing!
