Goliathus
Pachnoda
Euphoria fulgida, the Emerald Euphoria - captive bred generation F2 is now emerging. The original stock was collected in Kansas, from thistle flowers. They measure around 17 mm, on average. This species has a long larval diapause after making a cocoon. The cocoons are made using clay soil - they don't seem to be able to form cocoons properly using organic substrate, as Gymnetis thula does.

Interestingly, the larvae grow to a much larger size than would seem necessary to produce an adult beetle of this size.
