If the weather is too warm, they may be unable to go into hibernation and not expand their life spans by the full four months. Sometimes the straggler butterflies who do not fly all the way to the major Monarch Butterfly groves will not survive all winter; sometimes they will be the ones who do survive.

Hibernating Monarch Butterflies wake up and fly from time to time; they like to hibernate near sources of water and fly down for a drink when they wake up. Some changes in their bodies do take place while they rest. For one, by February the mild poison they absorb from milkweed begins to break down, allowing some predators who have eaten one Monarch to consider eating another one. That does not happen at other times of year. However, enough of their body processes shut down that instead of dying and giving place to another generation in October, most Monarch Butterflies complete migration, then mate and lay eggs in February.

No Monarchs hatch between October and February. However, in Florida, along the Gulf Coast, and in Mexico it is sometimes possible for Monarch Butterflies to stay active all winter, laying their eggs on a tropical species of milkweed and producing one or even two extra generations of Monarchs in winter. When Monarch Butterfly populations started to decline, some people thought that extra generations would restore population counts. Actually, as those people learned, interfering with the normal Monarch Butterfly life cycle created some problems.

Tropical milkweed can harbor tiny parasites that weaken butterflies. Monarch Butterfly migration is strenuous for the butterflies. Not all individuals who migrate survive. Monarch Butterflypopulations normally decrease in winter, but this offsets their increase in summer and keeps the species in balance. Some scientists consider D. These butterflies are better adapted to live in their environments, with little competition from D. Fortunately, nature has limited the extent to which Monarch Butterfly populations can be affected by the possibility of individual butterflies producing extra generations.

Slight variations in the general Monarch Butterfly life cycle are possible; major changes would be harmful. Our articles are free for you to copy and distribute. Make sure to give www. Monarch Butterfly.

They multiply their body mass several thousand times, shedding their exoskeletons as they outgrow them.

This can happen a number of times before they pupate, when they form a chrysalis and transform into an adult butterfly.

Instead, most butterfly caterpillars pupate by hardening into chrysalises, which serve as protective shells as the insects mature into adults. This complex stage lasts just days in most species, during which the larva body liquefies and is rebuilt as a butterfly. In some species, found in extreme environments, butterflies can stay inside their chrysalis for years, waiting for favourable temperatures or other conditions.

Because temperature is one of the main triggers for this stage of the life cycle to end, butterflies that form their chrysalis inside human dwellings can emerge early, prompted by central heating.
