This table compares the insect taxa that were the subject of study in the research literature with those included in the textbooks as examples of sexual selection. The percentage for each book is presented individually, followed by the collective proportion for that taxon across all of the books collectively, and finally the proportion that taxon represented among the insects studied in the peer reviewed articles
