Etymology
editThe species name fragile is a Latin word meaning fragile, or easily broken. In 1906, Robin Tillyard named this species probably in contrast to other members of the genus Ischnura, where it had been provisionally placed.[7][8] While the name was originally spelled "fragilis", the ICZN mandates that species names that are adjectival must agree in gender with the genus name, so when this species was moved to the genus Aciagrion, which is neuter in grammatical gender, the spelling of the species name changed to fragile.[3]
