(Kansas:Sedgwick County: Lincoln and Rock Road: 37 40'N/97 14'W on a tree August 25)

Diagnosis- Adult T.Dorsata have two pairs of clear membranous wings folded over their abdomen. They have stout bodies and broad heads. They have large compound eyes. Their mouth parts are piercing sucking. Females and males have the same characteristic brown, white, and black markings. The males are around 3 cm females are slightly smaller. Males can be identified by the presecence of tymbals. Tymbals are a form of striated muscle that expand and retract rapidly to produce a species specific mating call. The newly molted adults can be identified by the absence of a white waxy buildup

Nutrition- They are herbaceous xylem ,of woody plant, feeders. The larvae feed also feed on the Xylem but its from the roots of woody plants. Feeding serves two purposes nutrition and body temperature control through evaporative cooling.

 

 

Natural Adult life history- T. Dorsata emerges every year from June to September. The average life span is 2 to 5 years majority is spent underground as a larvae.T. Dorsata is hemimetabolous. The female T. Dorsata will oviposit 500-600 eggs on a twig or leaf. Once the eggs hatch the larvae will fall then dig underground. There they will feed on the roots of a woody plant. When ready they emerge find a tree to attach then molt into an adult. Once their wings are dry they disperse and find a mate. When threatened, cicadas will play dead or let out a alarm squawk to scare the predator away. The males use their tymbals to sing. The singing tends to occur at the hottest hours of the day.
