Defect life cycle, also known as Bug Life cycle is the journey of a defect cycle, which a defect goes through during its lifetime. It varies from organization to organization and also from project to project as it is governed by the software testing process and also depends upon the tools used.
Bed bugs have five immature nymph life stages and a final sexually mature adult stage. They shed their skins through ecdysis at each stage, discarding their outer exoskeleton. Newly hatched nymphs are translucent, lighter in color, and become browner as they moult and reach maturity.
There are five progressively larger nymphal stages, each requiring a single blood meal before molting to the next stage. The entire bed bug life cycle from egg to adult takes anywhere between 5 weeks to 4 months. Adults live up to 10 months. Bed bug eggs are white to a pale creamy color. The bed bugs eggs are barely visible to the naked eye.
The bed bug life cycle starts with an egg. It is milky white in color, and about a millimeter long, resembling a grain of rice. Pregnant females lay three or four eggs per day (though sometimes as much as five), and up to 500 eggs can be laid in her lifetime. This high volume of eggs can allow a single pregnant bed bug to form a large infestation on her own. The eggs hatch within two weeks, and nymphs emerge.
The bed bug life cycle begins like that of most insects—with an egg. Bed bugs will only romance to fertilize eggs after a blood meal. They meet back up at their harborage (a community of bed bugs)
Under normal circumstances adult bed bugs will live for about 2 to 4 months. Bed bugs need to feed at least once before each molt, although they could feed as often as once a day. Young nymphs can survive without a blood meal for days up to several months.
