Polyphaga saussurei adult?

[Manuel_P]

Hi, I have kind of a stupid question...

How do I know if my P. saussurei are adult?

Here are a few pics





So are they already adult? I thought so, because their light markings on their thorax are not really prominent anymore..

I think so, Hisserdude will be able to tell you for sure.

Yeah, they look like adults, their pale markings become smaller and less prominent when they are mature.
