This is definitely a bug - as indicated by the characteristic body form and the segmented (it should be five) antenna. My guess here is that this is Nezara viridula, also known as the "southern green stink bug" or the "southern green shield bug".

See this image (from here):

Besides being a pest for agriculture, they are harmless and not toxic, although they can spread a stinking substance when threatened, hence their name. You can find more about them here and here.


Looks like a common green stink bug - https://en.wikipedia.org/wiki/Green_stink_bug

Give it a test. If you put it into a handkerchief and scare it a little, it should give off a foul smelling odor

  • $\begingroup$ the exact same bug is present in central Europe. I saw it today. So maybe the wikipedia article needs updating $\endgroup$ Sep 21, 2019 at 21:31
  • $\begingroup$ the edges around it's body might be different because of the age difference. The body shape (hexagonal back) looks identical though $\endgroup$ Sep 21, 2019 at 21:33
