Goliathus goliatus exists an all-white-form known as "quadrimaculatus." While it is not common, it's not entirely rare. However, the "quadrimaculatus" form is not known in Goliathus orientalis. Since its description in 1909, only forms such as orientalis, conspersus, pustulatus, undulatus, and preissi have been described. I may have stumbled onto something. My latest eclosion has revealed what appears to be the first documented case of "quadrimaculatus" in Goliathus orientalis. All his brothers and sisters exhibit the "preissi" form. Attachments:

Very interesting specimens! Have you a pictures of their "parents"?
It seems like from Tanzanian population.

Here is another dorsal view. The initial origin is Tanzania. Attachments:

That white male is great shame that so many other failed to emerge correctly, did you by any chance remove them from the cocoons before they hatched. That is great news that you are now hatching out larvae, Is that normal that they stay in the cocoon for so long after hatching compared to Goliathus goliathus, or is it just the conditions you had them in and they thought that it wasn't the rainy season yet. I have loads of Goliathus goliathus larvae if you are interested in swapping some depending were you are as i am in England. Here is a picture of my Goliathus goliathus that i hatched out about 3 months ago from which all my larvae are coming from. Biggest male was 84mm.

Dear Ian,
Thanks for your reply.
Goliath beetles die easily when removed from their cell (unlike rhinoceros beetles), so I leave them alone for at least 4 months before openning any cell.
G. o. usambarensis are beetles with characters. I've tried watering them, raising themperatures, coaxing them with beetle jelly. But they just don't become active for 5-6 months. At least 4 breeders here in Taiwan experience the same thing: 5-6 months for G. o. usambarensis, but only 2 months for G. goliatus.
Some people believe that goliatus, orientalis, usambarensis, regius are all the same species (just different regional forms). But judging from usambarensis' very long inactive period, I think it might be safe to say it is a different species, although usambarensis and goliatus can hybridize for sure, as some breeders have done so many years ago.

Here is a 75 mm G. o. usambarensis that JUST crawled out of the soil a few minutes ago. He "slept" for 5 months.  |

I think that one of the important factors for large beetles is the protein source, I am giving mine freeze dried river shrimp which they seem to like so far (biggest are just L3) which contain 60% protein.
Also when they start to wander, i put them straight into a bucket full of the sandy/substrate mix and put them in a slightly lower temperature.
With the adults that i have just had out all the larvae went down quickly and stayed down to pupate, with the largest larvae being only about 65g in weight which produced a 84mm beetle, so the quicker you can get them to stay down the less weight they tend to lose so producing larger adults.
