Quote – Holmes on ‘Entomology’
” I suppose you are an entomologist ? “
” Not quite so ambitious as that, sir. I should like to put my eyes on the individual entitled to that name.
No man can be truly called an entomologist,
sir; the subject is too vast for any single human intelligence to grasp.”

Hi Waldo,
i think this is some species of the genus Desmidium...
Could you post some more images, perhaps at higher
magnification ?
Thanks,

Gerd

Thank you, Waldo for posting another image !
Ok, no Desmidium, a Diatom. NikonUser is right,
it is some species of Fragilaria, but no suggestions,
which species, there are about 100 of them....
