I really wonder what this is:

enter image description here

I find it near pound in Czech Republic (Central Europe). It's 2 inches long, AP. half wide. It was quite fast.

enter image description here


It is a Coleopteran insect (Beetle order) in the Ground beetle (Carabidae) family. Based on the elytra (protective wings) and the dark first antennal segment, it looks like Carabus granulatus. C. cancellatus is very similar, but has reddish first antennal segments. I don't think there are any other similar species in the Czech republic, but don't know the fauna there well. Overall, Carabus has many species and several are native to Eurasia and can be a size of 2 inches.





  • $\begingroup$ I agree, based on the european species I know of, it should be Carabus granulatus, C. clathratus or C. cancellatus. I suspect all of them are found in the Czech republic. $\endgroup$ – fileunderwater Apr 16 '18 at 20:21
  • $\begingroup$ Scratch C. clathratus, which has pits between the elytra lines (instead of raised bumps). In my literature, the other two are separated by the color of the first antennal segment, which cannot be seen clearly in the picture. $\endgroup$ – fileunderwater Apr 16 '18 at 21:40
  • $\begingroup$ I am so sorry. I wanted to do better picture, but it run away as soon as it noticed me. But I have a picture, where it can be seen (I think so). Anyway I didn't put it there in first place because don't have clue how to identify a bug in science way. $\endgroup$ – L.Diago Apr 16 '18 at 23:23

    $\begingroup$ @user40760 The dark first antennal segment in your second picture says that it is Carabus granulatus. On C. cancellatus it is reddish in colour. $\endgroup$ – fileunderwater Apr 17 '18 at 7:49
