BeetlebreederGermany Posted November 14, 2021 Report Posted November 14, 2021 Hello, I wanted to ask if anyone here knows if Scarabaeoidea species from other genera than Mecynorhina , Eudicella, Oryctes and Euchirus can show that reddish brown chitin plate on their abdomens in L3? Additionally, if someone knows anything about the function or whereabouts of this morphological feature, I would like to hear about that. Best regards, BeetlebreederGermany Quote
Goliathus Posted November 14, 2021 Report Posted November 14, 2021 A shield to help protect against predators attacking from the rear, presumably. Among the cetoniine scarabs, it seems to be unique to certain genera of Goliathini (e.g. Mecynorhina and Eudicella). Quote
BeetlebreederGermany Posted November 21, 2021 Author Report Posted November 21, 2021 Hello, that‘s what I‘m thinking as well, but I can’t seem to find any scientific studied on that, but I‘ll continue searching. The unique feature thing is something I have noticed as well... weird how it pops up. Thanks! BeetlebreederGermany Quote
