Beetle collection

[Primož]

Hello.

Can someone identify the beetle species  0:39 seconds?

I am mainly interested at the bigger Rose chafers in the middle they look like Cetonia aurata but seem bigger.

Thanks.

 

[Goliathus]

Agestrata sp. (possibly A. orichalca).  I've heard that this genus is difficult to rear in captivity.

Dont find much on them on Google.

Not much appears to be known about the biology of Agestrata.  It may possibly be that the larvae are specialist feeders -
