© THE KATYDID (Scudderia) How marvelously equipped such a creature as this is to live! The great eyes, with many facets,enable ittosee bynight aswell asbyday. Its long, slender antenna catch the faintest odor, and probably are sensitive to a host of perfumes that we donotknow. Inthe front ofeach fore leg, just below the knee, is a dark, sunken area-the ear-with which it can probably hear sounds toofaint for our ears, and bymoving them can tell from which direction the sounds come. Its long muscular legs enable it to jump great distances, and itswings not only enable itto fly well, but in the males are provided with an apparatus near their base for making a musical sound.This sound ismade byhalf opening the long green wings and closing them again rapidly. While the wings are opening no sound is produced; asthey close thecharacteristic sounds so like the words "Katy did" are made. Photo and note by David and Marian Fairchild.
