Gymnetis flavomarginata

[Dynastes]

(newly relegated to G. caseyi)

I have way better pictures around somewhere. This photo is probably from a scan of a 35mm print made a long time ago (though I remembered the 35mm prints being much nicer). It's a really pretty beetle but a color morpher like Dynastes (yellow turns black green).

Here's a more representative one.

Nice pic. What lens did you use? Digital, what mag?
