Distribution
(
Fig. 95
). Expanding its range northward in the recent years, this pantropical species reached
Canada
(
Pilon & Lagace 1998
), eastern Siberia north of Vladivostok (D. Grand, unpubl. data) and the Balkans (
Ober 2008
). In
New Caledonia
, it is recorded from 40 localities and
Bigot (1985)
reports it from Ouvéa. Some specimens, collected in
1999 in
the Bourail municipality (Gouaro) and in
2003 in
La Foa (Pocquereux valley), are preserved in the
CXMNC
collection.
Habitat.
Pantala flavescens
is found in a wide range of mostly sunny habitats, including coastal swamps, tempory pools, ponds and lakes, as well as slow open sections of rivers, streams and pools in torrents. It tolerates brackish water.
Biology and behaviour.
Its larva, illustrated by
Lieftinck (1962)
, lives in diverse habitats, including those lacking aquatic vegetation and development is extemely rapid (
Corbet 1999: 218
). Exuviae are found on any potential perch that emerges from the water. This highly migratory species is able to cross stretches of ocean of several hundred kilometres. Adults, which spend most of the day airborne, can be observed in urban areas, at higher altitudes or in forest clearings, typically flying comparably high and sometimes forming vast feeding swarms. Males are moderately territorial and mating takes place in flight at a height of
2–3 m
and lasts about a minute. The female oviposits alone, often at several well-separated sites, rapidly touching the water surface about a dozen times with the tip of her abdomen during each bout (
Grand 2004b
).
Status.
Without known threats,
P. flavescens
is ranked LC.
