The migration of animate being species is a vernacular natural result that happens each fall across the North American continent . Many species of bird and even mammals , such as the great giant , travel thousands of mile to over - wintertime in warmer climates . Check out these photograph of one of the most spectacular migrations .
Mass migration
Surely one of the most unique and amazing migration events occur each fall when thousands and thousands of monarch butterfly ( Danaus plexipus ) transmigrate to the warm mountains of central Mexico and the coastal region of southerly California . ( Credit : NPS )
Getting to sleep together this beauty
Monarch butterflies are tropical insects . Their family range broaden as far north as Canada . They may be the most recognized of all butterflies , with their beautiful and distinct orangish , white and black wings . The insects range throughout Canada , the United States and Mexico . During their larvae stage , the milkweed butterfly caterpillar eat almost alone on the common milkweed works ( Asclepius syriaca ) , while grownup butterflies feed upon the nectar of bloom .

unequalled among their kind
Monarch migration is unique to all butterflies found in North America . Some single butterfly stroke travel upwards of 3,000 mile ( 4,830 klick ) and can vaporize at altitudes as in high spirits as 10,000 feet ( 3,050 meters ) . They are the only butterfly mintage to make such a long , two - way migration every year . Their materialization return each wintertime to the same wintertime roosts and even to the same trees used by previous monarch generations . ( deferred payment : NPS )
Wintering in Mexico
If the Danaus plexippus butterfly stroke has spent the summer east of the Rocky Mountains , it will trip to the Sierra Madre Mountains of Mexico . Here , they are live as Mariposa monarca and will expend the wintertime day from October to former March in the affectionate , unequalled habitat of oyamel fir tree trees ( Abies religiosa ) .

Wintering in the Golden State
If the crowned head butterfly has spent the summer Cicily Isabel Fairfield of the Rocky Mountains , it will travel a shorter distance , to the many grove of Monterey pine(Pinus radiaita ) , Tasmanian bluegum eucalyptus ( Eucalyptus globulus ) and Monterey cypress ( Cupressus macrocarpa ) found along the coasts from northerly to southerly California .

phratry secrets
All monarch butterflies seems to apply environmental clues to stimulate the beginning of their annual journeying . It is speculated that the shortening length of daytime and cooler temperature playact a character in the beginning of the migrant journeying . The position of the sunshine in the sky and the magnetic pull of the Earth may both help in the butterfly ' accurate seafaring . Monarchs will travel to the very same Tree each twelvemonth , which is an amazing fact of nature when one realizes that they are not the same butterflies that used the tree the premature winter . In fact , they are three to four generations removed from the previous wintertime ’s butterflies . ( Credit : NPS )
regain shelter on the road
Monarchs have been known to travel between 50 to 100 stat mi ( 80 to 160 klick ) each day . The tenacious journey can take upwards of two months to complete . One tagged monarch butterfly stroke was recorded to have jaunt some 265 stat mi ( 430 km ) in just one day . Since monarchs only change of location during the day hours , they must receive protective environments in which to roost each night of their journey . Some such roosting sights are known to be used year after yr by the migrating Danaus plexippus butterflies . ( Credit : NPS )
Power of the masses
Once they reach the Tree in which they will over - winter , the crowned head butterflies will cluster together to stick around warm . ten of thousands of beautiful orange tree butterfly can cluster together on a single Sir Herbert Beerbohm Tree . Even though a single monarch weighs less than fraction of an troy ounce , the monolithic clustering of butterflies exert a heavy exercising weight on Sir Herbert Beerbohm Tree branches , which sometimes discontinue from the combined free weight of the butterfly .

wintertime cluster
One of the largest colonies of milkweed butterfly butterfly find along the California coastline is found in the quaint and Graeco-Roman beach town of Pismo Beach . The butterfly begin make it at their wintertime home in mid - October , allow visitors to at leisure walk beneath the branch of a modest grove of eucalyptus trees and gaze upon some 25,000 beautiful butterflies clinging to the leaves and branch .

A long winter ’s nap
During the tenacious winter calendar month , the M of sovereign butterflies rest relatively inactive , hold out on their store fat reserves . During a affectionate , sunny day , single butterfly stroke will flutter about or be interpret on the ground , bask in the strong sunshine . The Pismo Beach monarchs will stay on in the eucalyptus grove until late February , when they become participating again and begin the migratory journey north . ( Credit : Linda & Dr. Dick Buscher )
Vulnerable and protect
Since monarch butterfly only over - winter in a few location , they are extremely vulnerable to any outstandingly cold weather condition at those sites that can kill thousands of them . So , too , do they face great danger from the destruction of their habitats from human activities . Most of the declamatory monarch over - wintering internet site along the California coastline are now protect as Danaus plexippus sanctuaries . ( Credit : Linda & Dr. Dick Buscher )
Generation after multiplication
When the quick weather and lengthen daylight hour come again with a new spring , the monarch butterfly stroke of Pismo Beach will become alive again . They before long become procreative and set about laying their eggs , give hike to a new generation of caterpillars and soon - to - be adult butterflies . Unlike their parents , who made the migration to the south and west , this contemporaries of monarch butterfly will make their migratory journey back to the east and north . ( Credit : NPS )
Breathtaking wonderment
The migration of the monarch butterflies is certainly one of nature ’s most amazing phenomenons , and is made even more particular by the monarch sanctuaries along the California coastline that receive visitors to see , watch and enjoy all about these beautiful creatures of our born world .
