“There are earlier records of swarms of dragonflies flying out to sea, and at sea.
But it was always assumed that those dragonflies were doomed. Which says rather more about our earth-bound lack of imagination than it does about the globe skimmers’ extraordinary flying abilities.”

<H3>A remarkable dragonfly migration stretching between 14,000 and 18,000 
kilometers has been discovered which spans the Indian Ocean.</H3></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://ecoworldly.com/2009/07/22/14000km-dragonfly-migration-discovered-longest-of-any-insect/"><div align="center"><img src="http://content7.clipmarks.com/blog_cache/ecoworldly.com/img/45824F68-855C-45D1-92B1-F02415F3132A" alt="dragonfly" /></div></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://ecoworldly.com/2009/07/22/14000km-dragonfly-migration-discovered-longest-of-any-insect/"><H4>The migration is by far the longest known insect migration, dwarfing the 7,000km journey of monarch butterflies. Millions of dragonflies make the epic migration every year, which spans from India to the Maldives, the Seychelles, Mozambique, Uganda and back again.</H4></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://ecoworldly.com/2009/07/22/14000km-dragonfly-migration-discovered-longest-of-any-insect/">the journey appears to follow the rains, from the monsoon season in India to the 
rainy season in eastern and southern Africa. The swarm of dragonflies complete a 
total of 4 generations by the time the entire migration is completed. 
Furthermore, the trip is mirrored by the migratory paths of a number of 
insect-eating bird species, which scientists now know must feed on the 
dragonflies as they travel.</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://ecoworldly.com/2009/07/22/14000km-dragonfly-migration-discovered-longest-of-any-insect/">Perhaps the only thing more amazing than the migration is that it has somehow 
dodged scientific discovery until now.</blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/D199BC94-F2FA-4CF4-827D-E6BE4DB0C6AC/blog/" title="blog or email this clip"><img src="http://content8.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
