In biology, a biological life cycle (or just life cycle when the biological context is clear) is a series of stages of the life of an organism, that begins as a zygote, often in an egg, and concludes as an adult that reproduces, producing an offspring in the form of a new zygote which then itself goes through the same series of stages, the ...
The males aggregate in chorus centers and call there to attract mates. Mated females lay eggs in the stems of woody plants. Within two months of the original emergence, the life cycle is complete and the adult cicadas die. Later in that same summer, the eggs hatch and the new nymphs burrow underground to develop for the next 13 or 17 years.
The earliest fossils of cicadas more closely related to Cicadidae than to Tettigarctidae date to the Jurassic period. The morphology of well preserved stem cicadids from mid-Cretaceous Burmese amber from Myanmar suggests that unlike many modern cicadas, they were either silent or only made quiet sounds. [2]
Some species have much longer life cycles, such as the North American genus, Magicicada, which has a number of distinct "broods" that go through either a 17-year (Brood XIII), or in some parts of the region, a 13-year (Brood XIX) life cycle [51] The long life cycles may have developed as a response to predators, such as the cicada killer wasp ...

Cordylobia anthropophaga, the mango fly, tumbu fly, tumba fly, putzi fly, or skin maggot fly, is a species of blow-fly common in East and Central Africa.It is a parasite of large mammals (including humans) during its larval stage. [1]
During the aggregation phase of their life cycle, Dictyostelium discoideum amoebae communicate with each other using traveling waves of cyclic AMP. [51] [52] [53] There is an amplification of cyclic AMP when they aggregate. [54] Pre-stalk cells move toward cyclic AMP, but pre-spore cells ignore the signal. [55]
