Tripe. The TaNaKh was written in Hebrew and we Jews know what it says. The back legs of certain insects such as locusts have a jointed hind leg designed for jumping which have a special name in Hebrew וקרצולים. Some other insects, including some beetles, have similar hind legs. Which is why the Scriptures include multiple characteristics that the kosher insects must have. An insect is only kosher that has
all of the characteristics. You are arguing from ignorance. The Jews have had these Scriptures for thousands of years and understand them quite well. They would have discovered if there was an inconsistency or error long before you came around to point it out.
