If this are blue flowers then no. Then it is E. ritro (http://agrozoo.net/jsp/Galery_one_image.…8af273b74&l2=de). Else it might be.
I have blue flowered in my garden, I dont know where it grows naturaly but apparently it does somewhere in Slovenia.
If not otherwise stated all my observations are from Slovenia. Exact location can be found under linked image (the one with checkmark).
How do I do to 1/100 mm exact measuremets of bugs ..--> http://agrozoo.net/jsp/Help.jsp?p1=help_object_measure&l2=en
Hi,
Thanks a lot for your answer. By mistake I posted this text twice. Sorry for that. Now I definitely know that it is E. sphaerocephalus, as its blossoms are white.
Regards
Gabriele
