Goliath beetle pupation

Originally shared by Austin O. in the IB EXOTIC community.

Hello!

So I received a goliath beetle larvae early June (its now mid november) so its been about 5-6 months and i received the larva as a L1-L2. I'm not super familiar with their lifecycle timeline (I worked with tobacco hornworm a lot previously but never these guys). From what i have observed I believe they have gone through their wandering phase and should have been entering their pupation stage. But they have just been holding on... i notice they are still up and about and often will hang out on their back on top of their substrate (currently using the white oak substrate from the beetle bros). I'm wondering if anybody can comment on their behavior during this stage and if this is normal/ if i should be doing something. Thanks so much for your time and help!
