An insect of the family Gracillariidae; a leaf-roller moth with a complex life cycle.
From Gracilaria (probably through taxonomic naming) plus '-id' (member of a family). The family name comes from the genus Gracilaria, though the connection isn't entirely clear.
Gracilariid moths have an amazing trick—the larvae roll or fold leaves into tiny shelters while eating from inside, creating nature's origami! Some species have never been seen by scientists.
