I finally managed to make a trailer for my video channel on Youtube. I guess that "the making" was motivated by this lock-down effect as I had a huge surge in number of questions in my email inbox. The trailer features some of my beetles and its content was massively saved by a free music track :). For those who have not yet seen the video, please watch it below. It also seems that answering some questions is easier in Youtube comments, so I would be happy to answer most, if not all, beginners questions there (to the best of my knowledge :).
Please also do not forget, about this post for beginners

and this post about substrates

These posts will provide most of the information which you would need to start with beetles. The internet these days provides lots of useful data about different species, so please research well before getting a beetle :)
