Green fruit beetle

[critterguy]

Ok, down in So-cal right now I am seeing quite a few of these. Do they make good captives?

 

[Dynastes]

The adults live a few months. They lay eggs readily and the grubs are easy to grow but getting them to pupate and change into adults correctly is extremely difficult.

 

[critterguy]

Well, have you succeeded?

 

[Dynastes]

I've reared Cotinis to maturity a few times but I wouldn't call it success.

Do they require diapause to mature during pupation??

No, it's just difficult to provide the proper nutrition without massive mite problems and then pupal cell formation and eclosion include many troubles.

have you tried with lower humidity level?

If you limit the humidity you'll cross over the point where you damage the larvae before you reach the point where you kill the mites. Short-term you can dry out the mites and not the larvae without substrate only. It's not an impossible species but it's far more difficult and time intensive than other flower beetles. Gymnetis caseyi on the other hand is an extremely easy to rear USA native.

Thanks Orin for your comments.

I hope to be successfull with my Gymnetis breeding!.

I will try with my next Cotinis breeding.
