As we have seen in many of my past photos, common names can be very misleading. While the term "bug" is often used for any insect, it really only applies to one group, order Hemiptera, which included insects like Stink Bugs and Assassin Bugs as well as aphids, cicadas, and leaf hoppers. The June Bug is actually a beetle. So are Lady Bugs and Lightning Bugs. As much as common names "bug" taxonomists, even Entomology books include them, so it is important to understand that they might not be taxonomically accurate.
