New Hong Kong dragonfly
Macrodiplax cora, a dragonfly newly recorded for Hong Kong in May 1997 (see Porcupine! 16: 5), is a widespread species found in three zoogeographical areas - the Ethiopian, Oriental and Australasian regions. It is highly migratory with populations established on islands in the Indian and Pacific Oceans. The larvae are salt tolerant with populations occurring in lagoons and estuaries. The genus Macrodiplax is both tropical and neotropical and closely allied to Pantala which is also found throughout the tropics. Macrodiplax cora and Pantala flavescens are perhaps today's most successful dragonflies in terms of numbers and distribution.
