Number 6587. This is a nymph of a dog-day/annual cicada (Hemiptera/Auchenorrhyncha: Cicadidae). The nymphs spend three to five years underground feeding on sap from roots, and when fully grown, they tunnel up to the surface to find a safe place for the adult winged insect to emerge from its nymphal ‘shell.’ They are called annual cicadas because some emerge every year, and dog-day because their peak emergence usually in late summer (the dog-days).
