Dragonfly and damselfly migrations crisscross planet, with 100 species confirmed

Migration flights of dragonflies and damselflies crisscross much of our planet, new research reveals.

Scientists from the universities of Exeter and Lund reviewed global evidence and found 100 dragonfly and damselfly species that migrate, and a further 85 possible migratory species.

This means that only 1.5% of all dragonfly and damselfly species migrate (or 2.9% including possible migrants)—but the migrations can include millions of individuals, and some travel thousands of kilometers.
