Megasoma vogti question

@JunkaiWangisme @Beetle-Experience
I went to Davis Mountains last year.. (UV trapping at one location only two nights straight) Found Chrysina gloriosa, was little late for C. woodi, found lots and lots of non-insect inverts with Alan, just outside tent.. lol. Found a single male of Xyloryctes thestalus. It was a dry season, with no water stream at all, everything was kinda dried out, and dying from low humidity, so it wasn't the best time of the year. No records of Megasoma vogti was even there when I researched ahead of trip. (actually couple weeks early for M. vogti too). I can't remember the name of place, but there was a protected area near Davis where M. vogti has been recorded multiple times. (look up either iNaturalist or BugGuide!) I tried to contact their office hoping I could access there, since overnight camping as well as hunting is allowed (in hunting season), but..... The office closed an hour earlier than posted office hours, so never even had a chance.

I went to Davis to light for a night, then backpack. I wasn't planning to find vogti there, gave up after San Antonio was a bust... Davis I went to early August, got 3 woodi, some gloriosa, and probably 30+ Xlyocrates, but the Xlyocrates didn't breed for me sadly.

Surely, any records of M. vogti in the Davis Mountains are in error, as that area is much too far west for this species?  I've not heard of vogti being found any further west than the area around Brackettville.

Yeah....its not Davis. Its closer to central TX

 
Th thing with this species is you'll never see them outside a monsoon season. You have to hit the spot right after it gets a heavy rain or you wont have any luck. Also, larvae often starve and die if you change out their substrate (like many other Megasoma species) so couple of people who tried them lost their culture this way.

 
1. Do you put the larvae together in a large container?

2. When they turn L2 do you put 1 in each individual container separately?

3. Can you filter out the frass and mix the old substrate with new substrate without any problems?

I was told its best to just move the eggs to the enclosure you'll keep them in until they turn into adults with no substrate change
