![]() ![]() The dog days refer to the hot days of summer when the Dog Star Sirius, which is part of the constellation Canis Major, rises at dawn together with the sun. The whole process may take up to a few hours before the insect has hardened, changed colors and is ready to fly into the safety of the trees.ĭog-day cicadas are named for the time of year during which they are noisily conspicuous. The dry husk of their exoskeleton will remain clinging to the trees bark like a rock climber frozen in time. Clutched to the bark of the tree, the exoskeleton of the nymph will split open on the dorsal side and the soft, plump light green shape of a winged adult cicada will soon crawl free of its past life. The insect will go through a metamorphosis of sorts and begin life as an adult. ![]() ![]() Once on the surface, they search for the base of a tree and climb a few feet up the trunk. After about three years of digging around in the dark, the nymphs will emerge from their subterranean home when the ground temperature reaches around 64 degrees. Here, they will search for tree roots, then sink their needle-like mouth parts into the roots and extract the sap for sustenance. Using their powerful legs, they will burrow into the ground where they will spend practically their entire life. After about six weeks, the eggs will hatch and the tiny nymphs will fall to the ground. Each female will lay more than 500 eggs in clusters of 15 to 20 eggs. She uses her rasp-like ovipositor to cut a trough into the bark where she places her eggs. These cicadas begin their life as an egg that is laid by the female in tree branches. They differ from the periodical cicadas that emerge after 13 or 17 years. The dog-day cicada is a type of annual cicada that emerges from underground every year. The cicada’s three small, simple eyes are visible in between its two large, compound eyes. Like a sound machine, it is nature’s lullaby, the call of the cicada, a white noise that can lull you to sleep on the soft breeze of a summer afternoon. We grow so accustomed to the noise that we almost don’t even notice it. In mid-summer, the sound starts gradually and gains strength each day as new members join the chorus.
