Hello all. This is my first time posting a topic on the forum so please tell me if I am doing something wrong, or if this is not the right place to ask a question like this.
I recently went to the library and got the DK handbook “Insects” because I want to learn more about them. The book features most of the main insect families. In the beginning of the book, there is a page called “What is an insect?”, and it features an image of a dissected beetle which I will include a picture of. The beetle was labeled as Xixuthrus heros, the giant Fijian long-horned beetle. I was drawing it in my notebook when I decided to look it up online. None of the pictures that I found looked the same as what was in the book. After uploading it to iNaturalist (not to post just to use the AI identifying tool), I think that this was not an image of Xixuthrus heros. Now I am not a beetle expert by any means but I think it may be a member of the genus Callipogon and not Xixuthrus. Just compare the following pictures:
^^ this is the book page
^^ This is Xixuthrus heros
^^ And this is Callipogon barbatus, which I think may be the beetle depicted in the book.
You can even see the striking differences in the elytra of Xixuthrus heros vs Callipogon barbatus. Every time I look at the pictures of Xixuthrus barbatus I see how different it is from the beetle picture in the book! And also, I do believe that the version of the book I borrowed was the 1st edition published in 2000, and I think there is a second edition that was published in 2002. I wonder if the second edition copy of the book has the same error, if I am correct in thinking that it was an error? (Can anyone confirm this or correct me? Thanks!
