You should know know by now that in entomology the word “bug” is a term of art, referring specifically to members of the order Hemiptera, which includes creatures like aphids, cicadas, and leafhoppers. Things like “ladybugs” are really beetles, in the order Coleoptera. Here’s a “true bug” picture taken by naturalist/photographer Piotr Nackrecki (personal website here, natural history website here), with his caption indented. It’s one of the most beautiful insects I’ve ever seen.
A beautiful Neotropical gem – lantern bug Scaralis neotropicalis from Costa Rica.
