It was a bit unexpected. Moreover, I found it again later and that one was the first to be identified; Only then I could realise something like “deja vu”. The appearance of this firstly is only related to chronology.
Thanks, Jason, for your kindness.

Neat species!

Great specimen and observation! I just saw it for the first time a couple of weeks ago. What a beautiful and unexpected thing to find under one’s microscope. :)
