Film Critic Morgan B. Film Critic, Age 10 Flight of the Butterflies is an amazing, beautifully shot film that is a wonder for the eyes. This film centers on a scientist named Fred Urquhart who, as a child, wondered where butterflies go during their migration.
June 13,British Ecological Society A painted lady butterfly. Gerard Talavera and Roger Vila, CSIC Previously known to migrate from Europe to the Afrotropics during the autumn, the fate of this butterfly species and its offspring remained unknown.
Researchers were now able to demonstrate that painted lady butterflies return from the Afrotropical region to recolonise the Mediterranean in early spring, travelling an annual distance of 12, km across the Sahara Desert.
Their results were published today in the journal Biology Letters. This butterfly species travels 12, km and crosses the Sahara Desert twice to seasonally exploit resources and favourable climates on both sides of the desert.
Few species are known to perform annual long-range trans-Saharan circuits, and that of the painted lady is the longest migratory flight known in butterflies to date. In a previously published studythe researchers demonstrated that painted lady butterflies migrate from Europe to tropical Africa by the end of summer, crossing the Mediterranean Sea and Sahara Desert.
The fate of these migrants and that of their offspring remained unknown. The answer is in the wings With the aim of confirming this hypothesis, they studied the natal origin of the butterflies that reached the Mediterranean region in early spring. To do so, they analysed the stable hydrogen isotopes of the butterflies sampled in Morocco, Andalusia and Catalonia in Spain, Crete, Egypt and Israel.
An isotope is a form of a chemical element whose atomic nucleus contains a different number of neutrons compared to protons in the nucleus.
In water, the proportion of hydrogen and its stable isotope depends on the geographical location.
When absorbing water, this proportion is maintained in plants; it later remains in the caterpillars that feed on these plants, and, eventually, in adult butterflies. By analysing the hydrogen stable isotopes found in the wings of adult butterflies, the researchers could determine where they had developed as caterpillars.
This is why finding out where a butterfly grew up before undergoing the metamorphosis by means of stable isotope analysis turns out to be extremely useful.
It feels like magic", says Gerard Talavera, who led the research.
The results show a major proportion of specimens stay in the Afrotropics during winter and that those recolonising the Mediterranean are most probably their offspring.
This scenario closes the loop for the Palearctic-African migratory system of Vanessa cardui and shows that the annual distance travelled by the successive generations may reach about 12, km, including crossing of the Sahara Desert twice.
Whether the Painted Lady does regular migratory circuits similar to those of the monarch butterfly in North America was a matter of scientific debate.
This research reveals the parallelisms in such a unique evolutionary adaptation.Spreading an awareness of butterflies with information on life cycle, butterfly gardening, live caterpillar larvae kits, butterfly jewelry and butterfly gifts.
Despite their small size, butterflies and moths are some of the world's most wondrous animals.
Their beauty, seemingly miraculous metamorphosis, and apparently carefree flight all spark our imaginations. The sticker tags do NOT hurt the butterflies or disrupt their flight pattern at all so don’t worry about that!
Once we do a full year with our butterfly tagging at school I will update the post to see what percentage of our butterflies made it! Flight of the Butterflies is an interconnected scientific adventure story that spans not only thousands of miles, but generations.
It’s about the remarkable Monarch butterfly migration, the most incredible migration on Earth, and the determined scientist who spent 40 years trying to discover exactly where the butterflies mysteriously /5(). Nov 12, · Someone on Facebook recommended Flight of the Butterflies as a worthy 3D release.
Though I can't say at the time I was a big fan of butterflies, I was intrigued that this title was packaged as a 4k and 3D Blu-ray combo for a very luring pricepoint. The Butterfly Garden features hundreds of butterflies!
The popular Joe W. and Dorothy Dorsett Brown Foundation Butterflies in Flight offers an amazing array of butterflies in a spectacular free-flight .
