In North the States it is but present during summer months (Evans, 1984). Butterflies begin to move south during crepuscle months, initially in small groups that join unitedly to get going flocks of thousands of male and female Monarchs (Evans, 1984). Western Danaus plexippus populations fly southwesterly; central and eastern populations fly south or southwesterly (Elzinga, 2004). Western populations spend winters in the Pacific coast range between Los Angeles and San Francisco. Tens of thousands of Monarchs spend winter in semi-hibernation, clustered on branches of Monterey pine trees and eucalyptus. In the spring months, pair occurs and both sexes exceed to their previous locations. Females stop along the commission to deposit ballock on milkweeds (Elzinga, 2004). Populations from the eastern United States hole up in a different area, but despite prolonged research involving the fall guy of thousands of monarchs to follow their route, their hibernation site remained a mystery until a a couple of(prenominal) years ago. The marking, which consisted of attaching a numbered label to the forewing of the Monarch, provided important information.

On the same day, a mark butterfly was found 77 miles away from its airplane pilot capture site (Pennesi, 2003). It was found that the marked butterflies were traveling towards Mexico, but the trace lines disappeared at the Texas state line. Estimates catch b! een made that roughly fourteen million Danaus plexippus depose be found hibernating in a region further four soil in area. Monarchs are capable of quick up to 30 km per hour. Total mileage of a migratory move around can total over 3000 km (Pennesi, 2003). They generally fly close to the ground; heights normally do not varying to a greater extent than 5m. Fall migration is more leisurely than the return during the spring. An estimated...If you want to get a luxuriant essay, order it on our website: OrderCustomPaper.com
