Abstract: In the tropical Indian Ocean, the Maldive Islands lack surface freshwater, so are unsuitable for dragonfly reproduction. Nevertheless, millions of dragonflies (Insecta, Odonata; mostly globe skimmer, Pantala flavescens) appear suddenly every year starting in October. Arrival dates in the Maldives and India demonstrate that the dragonflies travel from southern India, a distance of some 500–1000 km. Dates of arrival and occurrence coincide with the southward passage of the Inter… 
Isotopic Evidence That Dragonflies (Pantala flavescens) Migrating through the Maldives Come from the Northern Indian Subcontinent
The measured wing chitin δ 2H values in 49 individual Pantala flavescens from the November–December migration through the Maldives strongly suggests that the migratory circuit of this species in this region is longer than previously suspected, and could possibly involve a remarkable trans-Himalayan high-altitude traverse.
Seasonal Migrations of Pantala flavescens (Odonata: Libellulidae) in Middle Asia and Understanding of the Migration Model in the Afro-Asian Region Using Stable Isotopes of Hydrogen
It is suggested that in spring, the already-mature dragonflies arrive in Middle Asia for reproduction from tropical parts of East Africa and/or the Arabian Peninsula, and, in autumn, summer-generation dragonflies migrate to the south, and in the Afro-Asian region there is an extensive migration circle of the globe skimmer covering East Africa, Central Asia and the Indian subcontinent with a total length of more than 14,000 km.
First record of Pantala flavescens (Anisoptera: Libellulidae) from the remote Amsterdam Island, southern Indian Ocean
Analyzes the weather conditions in this sector of the Indian Ocean in February 2017 to assess the probability of arrival of the dragonflies by air from their known migration route at lower latitudes between India and East Africa and reports observations of Vanessa cardui (Nymphalidae) which has established a permanent population on Amsterdam Island and has been observed on several occasions in the Crozet Archipelago.
Migrations of dragonflies (Odonata) in the south of the West Siberian plain
A summary of mass dragonflies migrations observed previously in Russia, in particular in West Siberia, is presented and an original generalized classification of dragonfly migrations is proposed.
Unraveling the World’s Longest Non-stop Migration: The Indian Ocean Crossing of the Globe Skimmer Dragonfly
Insect migration redistributes enormous quantities of biomass, nutrients and species globally. A subset of insect migrants perform extreme long-distance journeys, requiring specialized morphological,

Large scale movements of these and other species raises questions about population connectivity, ecosystem impacts, the nature and evolution of cues that initiate migration, and effects of climate change on these phenomena.

Corrigendum to: Long-Distance Migration of the Globe Skimmer Dragonfly to Japan Revealed Using Stable Hydrogen (δ2H) Isotopes
The investigation underlines the power of combining stable isotope data with other information such as wind speed and direction, arrival dates, and body mass to estimate origins and to understand the life history of this and other insects.


Understanding and misunderstanding the migration of the monarch butterfly (Nymphalidae) in North America: 1857-1995
The present paper reconstructs the history of understanding the migration of the monarch butterfly in North America and reflects the spirit in which Charles Remington, then a graduate student at Harvard, and his friend and colleague Harry Clench founded The Lepidopterists' Society are reflected.
Simple rules guide dragonfly migration
The migratory patterns and apparent decision rules of green darners are strikingly similar to those proposed for songbirds, and may represent a general migration strategy for long-distance migration of organisms with high self-propelled flight speeds.
A field study of larval development in a dragonfly assemblage in African desert ponds (Odonata)
The results indicate that dragonflies cannot recognise whether a pond will retain water long enough for full larval development and oviposit in waters that will not allow larvalDevelopment, and may not have grown fast enough to emerge before the ponds dried up.

New records of birds from the Maldives
Fifteen species of bird were recorded from the Maldives for the first time, mainly during 2001–2007, which appear to be the first records of both Long-tailed Jaeger and Band-rumped Storm-petrel for the South Asian region.

We examined the convective activity over the tropical Indian Ocean in boreal autumn using satellite‐observation data. In November and December, we detected an intertropical convergence zone‐like
