Name
Mecistogaster Rambur, 1842

Mecistogaster is a genus of large Neotropical damselflies in the family Pseudostigmatidae, commonly known as helicopter damsels. There are eleven species distributed from Mexico to Argentina.[1]

Members of this genus have very long abdomens which they use to deposit their eggs in the water-filled rosettes of bromeliads growing on trees in the forest.[2]

Species include:

Mecistogaster amalia (Burmeister, 1839) - Amalia Helicopter[3]
Mecistogaster amazonica Sjöstedt, 1918
Mecistogaster asticta Selys, 1860
Mecistogaster buckleyi McLachlan, 1881 - Blue-tipped Helicopter[4]
Mecistogaster jocaste Hagen, 1869
Mecistogaster linearis (Fabricius, 1776)
Mecistogaster lucretia (Drury, 1773)
Mecistogaster martinezi Machado, 1985 (nomen obscurum)
