Family Gracillariidae

Leaf Blotch Miner Moths

Leaf Blotch Miner Moths have a wingspan as small as 4 mm, and seldom exceed a 15 mm span. The labial palpi are slender, 3-segmented and point forward, sometimes forward and upward. The maxillary palpi are 4-segmented. Tibial spurs are lacking on the front legs, but they are present on the middle (two) and back (four) legs.

The larvae of some species make inflated blotch-mines in leaves, and may partially line the mine with silk. Some make serpentine mines. Other begin life as leaf miners, and later emerge and fold the leaf to make a shelter. A majority of species mine in woody plants, but some are found in herbacous plants (Arnett, 2000).

Some species are diurnal, others nocturnal.
