Gracillariidae

The adults have narrow wings and long legs. Gracillariinae have a distinct head up resting posture supported by the legs.  The Lithocolletinae and Phyllocnistinae rest with the head lowered or body horizontal.

The larvae generally spend the first few instars in a gallery and then a blotch mine. They then feed externally, usually in a rolled leaf, often shaped like a hanging cone.
