A biologist in the Maldives is claiming that millions of dragonflies fly thousands of miles across the sea from southern India to Africa. If this hypothesis were confirmed, this would be the first known insect migration across open water. It would also dwarf the notorious Monarch butterfly trip taken annually, as their trip is just half the distance of the dragonflies. Biologist Charles Anderson has written his research over the mass migration in the Journal of Tropical Ecology. Annually,...

GAINESVILLE, Fla. -- Flowering plants near ponds may owe their pollination not only to the winged creatures of the air, but also to the finned ones of the deep. Scientists have discovered that fish indirectly help spread pollen among flowers near the water. That's because they eat dragonfly larva, which live in freshwater ponds and other water bodies. Adult dragonflies are major predators of bees, butterflies and other insect pollinators. The result is a simple but unexpected cascade: The...
