  1. Yesterday
  2. Thanks Teneb! Just saw the link you sent. Great videos!
  3. Hi all, This is my first time breeding beetles, so I'm still learning. Earlier this year I had a Chrysina gloriosa get apparently eaten by mites after it emerged. So I saw a ton of mites in my D.tityus pupal chamber containers and it looked like they had emerged in the chambers so I took them out so that they wouldn't get eaten by mites. I partially buried them in another tub with some old substrate and sprayed it a little. They were already hard but still dark brown. Should I wait till they turn yellow then put them in the fridge for diapause? Also do I need to feed them/offer water at this point or are they just gonna chill? They're moving around a little but mostly just sitting. @Nathan I saw you had some good advice with this species in some other posts, any words of wisdom? Others welcome to answer as well Best regards, Joe
  4. Yes, they are ovaries that you can find on female stag beetle larvae.
  5. Last week
  6. That last picture is of the larvae. I was shining an led flashlight on it as well. So I am correct then, the first two photos, the orange circled organ is ovaries?
  7. Give me some pictures of the back of the larvae. If you see the orange ovaries it is a female.
  8. And then here is the one I have been keeping, nothing seems to be visible. Not sure if any breeders can confirm, but seems like this should be a male if the article in the first post is correct?
  9. Here's the second grub I found today, also with that yellow/orange organ visible.
  10. So I was not able to compare my larvae to anything, until now! I examined my larvae for maybe 10-15 minutes, could not find any sign of the ovaries. However I also could not definitively figure out if I was able to find the black dot for the terminal ampulla, it seemed like it was possible but depending on how the grub was squirming about it was sometimes maybe possible I saw something other times nothing seemed visible. I was able to finally get out to the forest I found my grub in, and my goal was to find a few more grubs to compare it too. I found two grubs almost immediately under white rot logs, flipped over to see their back, and immediately noticed this yellow/orange oval shaped organ. So with that said, obviously I can't be 100% certain until it pupates, but is this a pretty good chance I have a male?
  11. Thanks, his legs are black so he should eclose in a couple days.
  12. @Teneb The hybridization done by Lucas of Insect Brothers is considered a hybridization, not a valid species. That is why He stated as a hybrid, not came up with some names. To become a valid species, the name has to be published in scientific journal. When I said a valid species, that's what I mean: "Published Name." G. atlas is a published name, so it is a valid name. However, normally, a hybridization between two (or more, if there is any) species are not given a name since it is rarely researched to be published because no one know whether it really is a hybridization between different species or just a variation, just like how the member @Goliathus has mentioned. That is why hybridization is usually referred as A x B. If Lucas of Insect Brothers, just randomly came up with a name like Goliathus insectbrotherus for that hybridization, then that's invalid name, since such name has never been published πŸ˜‚πŸ˜‚. A most recent study I was able to locate for the status of Goliathus (with barcoding) is a work done by De Palma et al. 2020. Here is a link to the research just in case anyone is interested: https://www.entomoafricana.org/ent afr 2020 25 1 De palma et al goliathus b.pdf
  13. In isopods and reptiles they are called morphs. so forms are just variations? Morph, form, and variation are all essentially interchangeable terms. Also the Regius goliathus hybrid Bred by insect brothers would in theory create a new species? No - it's a hybrid, in the same way that a cross between a lion and tiger, or a horse and donkey, are also hybrids. Hybrids can be fertile or infertile, depending on genetics. Incidentally, it's still not yet been truly established whether Goliathus "atlas" is indeed a hybrid between regius and cacicus, or simply a rare form that occasionally turns up within the regius gene pool. There are at least two (or more) rare forms of regius that look quite similar to atlas, but are not the true atlas, which is distinguishable from the others by a particular detail of the dark band that runs along the inner elytral margins (elytral suture).
  14. I want a beetle infestation! I would give anything for one!
  15. Woah, These are awesome! We have nothing like that in contra costa county.
  16. Hmmm check out aquarimax's videos on breeding them He will probably say I will give a link to his playlist
  17. Hmmm, maybe its getting older? or has just mated and pregnant? So its More clumsy?

  19. You may be right but it is spelled Braf on a dozen different pictures so it is not a typo. They were from a friend who speaks Czech and different languages spell many cities and countries differently.
  20. Might be a typo? Could it mean Brac? - https://www.google.com/maps/place/Brač/@43.3239049,16.373684,10z/data=!4m5!3m4!1s0x134a9b3548954eaf:0x927404eda9b10653!8m2!3d43.3048913!4d16.6527099?hl=en
  21. I have a few invert photos labeled Braf Croatia but it does not show up on searches. Anybody know where this is?
  22. The legs turn black days before they molt. If the body turns black they died.
  23. Exactly, Goliathus, I've seen plenty of "forms" listed on eBay as well, that's not even a subspecies, just a variation, like the spring and summer "forms" of Actias luna . Clearly a lot of individual variation within the genus. It'd be cheaper and easier just to make a poster out of that picture.. a 2D collection.
  24. Most of these are forms, rather than species. By the way, G. albosignatus albosignatus and G. orientalis undulatus have been left out. As for G. goliatus - in the words of entomologist Gilbert Lachaume (1983), some coleopterists have "amused themselves by naming a large number of varieties". I can't even recall all of the G. goliatus forms that I've seen listed on sites such as eBay over the years, many of which are not actually "officially recognized", and seem to have been coined by sellers. I believe that one such example, is hieroglyphicus -
