There are five subfamilies of Cicadidae: Derotettiginae, Tibicininae, Tettigomyiinae, Cicadettinae, and Cicadinae. Leafhoppers, spittlebugs, and jumping plant lice are close relatives of the cicada. Hemiptera is different from other insects in that both the nymph and adult forms have a beak (aka rostrum), which they use to suck fluids called <strong>xylem<\/strong> from plants. This is how they both eat and drink.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"\/images\/drinking-cicada.jpg\" alt=\"A feeding cicada.\" \ntitle=\"A feeding cicada\" width=\"207\" height=\"242\"><br \/><small>A Magicicada drinking from a tree. Photo by Roy Troutman.<\/small><\/p>\n<p>The body of a cicada is composed of a head, thorax &#038; abdomen. The head features two antennae, two compound eyes, three simple eyes (<a href=\"https:\/\/www.cicadamania.com\/cicadas\/can-cicadas-see\/\">ocelli<\/a>), a clypeus that connects the beak to the head (the clypeus looks like the grill of a combustion vehicle). The thorax features two sets of wings (forewings &#038; hindwings), six sets of legs, spiracles for breathing, opercula covering the tympana (&#8220;eardrums&#8221;), and in males of species that have them, tymbals &#038; tymbal covers. The abdomen features tergites (dorsal) &#038; sternites (ventral), more spiracles for breathing, and reproductive organs. <strong>Cicadidae<\/strong> and  <strong>Tettigarctidae<\/strong> have major differences in anatomy, <a href=\"https:\/\/www.cicadamania.com\/cicadas\/tettigarcta-tomentosa\/\">which you can learn about here<\/a>.<\/p>\n<p>The <strong>Latin root<\/strong> for the word for cicada is <strong>cicada<\/strong>.
