Large insects such as the cicada could provide a good source of nutrition to predators able to take them. An article in the Arkansas Gazette and Democrat reported them on May 25, 1855, with a note that some people believed them to be an omen of war because "they have red eyes, and the letter W (for war) on their wings." Brood XX of the periodical cicada appeared here in 1998, so brood XXI is due to appear in 2011. It emerges in great numbers and makes an incredible noise. Because these insects appear annually in the heat of late summer, they sometimes are called "dog-day" cicadas.Ī particular brood of a smaller species called the periodical cicada appears here only once every 13 years-May and June, instead of August. When the wings are firm, the cicada flies into the trees and begins making the characteristic calls usually heard in August. The adult stage first frees itself from the skin, then waits for the wings to grow. Close observation of an exuvium reveals fine details of the shape of the insect, and a crack along the thorax (the back) from which the adult has emerged (see photo).
#PREDATORS OF CICADAS FREE#
They climb up trees or whatever is available near their exit holes, latch on with the claws at the ends of their feet, and break free of their skins to emerge as adult insects.Ĭhildren often collect the shed skins, technically called exuvia, to hang wherever they please. After development underground, larvae come to the surface to metamorphose into adults, leaving holes about 1/2 inch wide that are commonly seen in late summer. Eggs laid under the bark of trees hatch, then larvae fall to the ground and enter the soil where they use piercing mouthparts to feed on sap from the roots of trees. Pictured here is a large insect called a cicada, a true bug known to many people as a locust (real locusts such as in "plagues of locusts" are grasshopper-like insects).
