I know that this headline is a little misleading; it conjurs up images of enormous moths straight out of the pages of one of Doctor Dolittle's lunar adventures, but the truth is - sadly - a treensy weensy bit more prosaic (though still exciting to a dyed-in-the-wool lepidopterist like yours truly).
