Hemiphileurus illatus

For about 3 years, I've lived and worked in an area of Phoenix where H. Illatus are common, although I grew up in the city and have never seen them anywhere else. Each year, a handful of them crawl into my house or office, and I can sometimes find them when I dig through my compost heap. I've kept them as pets and I think they're very cool so I'd like to give them the attention I think they deserve.  This is my effort to record details of the H. Illatus beetles I keep in captivity.

Summary of Captive Larva: Larva X1 - Found February 1, 2020: Pupated, eclosed. Deceased. Larva X2 - Found February 1, 2020: Pupated, eclosed.  Deceased. Larva X3 - Found October 17, 2022. Deceased. Larva A - Found April 3, 2023. Pupated. Deceased. Larva B - Found April 3, 2023. Pupated, eclosed. Still alive. February 2020 . These were found under some bricks in the garden. They pupated sometime later and both were males. I was not recording dates at this point. To the best I'm able to find records of, I found them on February 1 and put them in separate lidless mason jars of their native soil substrate. I dug them up once on March 1 and they were still larvae. On April 15 I dug them up again and they were adults. October 2022 . These were found in my compost heap when I shoveled up some dirt. I looked thoroughly for others but again, there was just a pair. The previous pair were the same size but one of this pair is smaller. Also, when disturbed, the smaller one started pooping, whi
