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 ...
When the rains begin, the beetle breaks open its cocoon, locates a mate, and the entire life cycle starts over again. The adult beetles feed on materials rich in sugar, especially tree sap and fruit. [1] Under captive conditions, adults can sometimes live for about a year after emerging from their pupal cells. [2]
Salps have a complex life cycle, with an obligatory alternation of generations. Both portions of the life cycle exist together in the seas—they look quite different, but both are mostly transparent, tubular, gelatinous animals that are typically between 1 and 10 cm (0.4 and 3.9 in) long.
Adactylidium is a genus of mites known for its unusual life cycle. [1] An impregnated female mite feeds upon a single egg of a thrips, rapidly growing five to eight female offspring and one male in her body. The single male mite mates with all his sisters when they are still inside their mother.
The Thecosomata (collective/plural: thecosomes, [1] meaning "case/shell-body"), [2] or sea butterflies, are a taxonomic suborder of small, pelagic, free-swimming sea snails known as holoplanktonic opisthobranch gastropod mollusks, in the order Pteropoda (also included within the informal group Opisthobranchia).
The eggs take 6–8 days to hatch, and there are three nymphal stages which together take 10–17 days before the adult develops, making a total life cycle from egg to adult of 16–25 days. Adults live for up to 30 days. [ 6 ]

Unlike all other known larvaceans, Oikopleura dioica shows separate sexes, which are distinguished on the last day of their life cycle through differing gonad shapes. [11] The immature animals resemble the tadpole larvae of ascidians, albeit with the addition of developing viscera. Once the trunk is fully developed, the larva undergoes "tail ...
