Nature Note #179: Strange Clicks and Whirring Trills

But despite being named for something else entirely (the name Katydid is allegory about a girl who refused to tell the truth about something and suffered dire consequences as a result), but this other name suits them just as well. Another insect that springs to mind is the water strider ( Gerridae ) which is often misnamed as the "water spider". However, according to a quick glance on Wikipedia, they are ...
