What is lost when you grow up not knowing the names for different varieties of fireflies? When you don’t have these words ready to pop on your tongue: Shadow Ghost, Sidewinder, the Florida Sprite, Mr. Mac, Little Gray, Murky Flash-train, the Texas Tinies, the Single Snappy, the Treetop Flashers, a July Comet, the Tropic Traveler, Christmas Lights, a Slow Blue, a Tiny Lucy, the mischievous Marsh Imp, the Sneaky Elves, and—in a tie for my personal favorite—the Heebie Jeebies and the Wiggle Dancer?
