The globe skimmer is one of the most widespread of the dragonfly species. It also has the longest known migration of any insect, let alone any other species of dragonfly (1,2,3). Their migration takes them from India to east Africa and back, covering distances of around 14,000 to 18,000 kilometres (1)! Imagine, a tiny insect, covering that far of a distance. What is also remarkable about this dragonfly is that the migration entails crossing the Indian Ocean, a distance of over 3500km (2,4). This transoceanic crossing is what brings them through the Seychelles.<\/p>\n<p>For such a tiny creature, with such a short life span, what would drive it to travel such distances? It\u2019s all about fresh water. The globe skimmer requires fresh water to reproduce. The migratory route follows shifting weather fronts, allowing it to also follow seasonal rainfall in order to reproduce (2). \u00a0In case you weren\u2019t already impressed, they also fly at altitudes of over 1000m along these winds. Several bird species also migrate along the same pathway (using the same winds) to their wintering grounds in Africa, seemingly using these dragonflies as a convenient food source.<\/p>\n<p>Next time you think of a big migration, give some credit to these globe skimmers, who for their size and lifespan, cover enormous distances.<\/p>\n<p>___<\/p>\n<p>(1.)
