【5.1cmの怪物】判別できない巨大個体を捕まえた。

I caught a mysterious giant stag beetle, 5.1cm long, and I'm not sure if it's a Dorcus rectus or a Dorcus titanus. If this is a Dorcus rectus, it might be an exceptionally large specimen, just 2-3mm away from the wild Guinness World Record of 5.4cm. However, I couldn't determine its exact species until the very end. I hope to show this stag beetle to my daughter during our next video call. Summer has just begun. #stagbeetle #stagbeetlecollection #giantstagbeetle #Dorcusrectus #Dorcustrumpetrum
