A dragonfly migration in the High Hindu Kush (Afghanistan), with a note on high altitude records of Aeshna juncea mongolica Bartenev, and Pantala flavescens (Fabricius) (Anisoptera: Aeshnidae, Libellulidae)

A large scale dragonfly migration across the main crest of Hindu Kush was observed on August 9, 1973 in the upper Mandaras Valley, at an elevation of about 6000 m. Due to the difficult terrain no specimens could be collected and therefore the identity of the species involved is uncertain. On July 25 and 28, however, 2 dead specimens of A. juncea mongolica Bart, were recovered on the Mandaras Glacier, at approximate altitudes of 4600 and 5000 m respectively. These are the highest hitherto known records of this species.
