Wow! What an interesting looking beetle. I have some photos of a red one that looks similar to this one. How awesome that you were able to get a photo of them mating! On a dandelion, no less. We were just talking about dandelions. LOL! Amazing photos @irvet! Thanks for using #insectpub tag. : )
Yes, the beetles were on the dandelion, I was a bit uncomfortable to disturb them at this moment :)
