Marmara arbutiella is a moth of the family Gracillariidae. It is known from Canada and the United States (Oregon, Washington and California).[1]

The larvae feed on Arbutus menziesii, Arbutus unedo and Arctostaphylos species. They mine the leaves of their host plant. The mine has the form of a very long, irregular, winding, serpentine mine just under the upper epidermis of the leaf. There are three behaviorally and morphologically distinct larval forms. There are six to eight sap-feeding and two non-feeding, structurally differentiated instars. The early instars are legless sap feeders. The first of the non-feeding instars never issues from the cuticle of the previous (feeding) instar. The second non-feeding stage is a fully legged, with rudimentary feeding structures and a functional spinneret. Upon issuing from the mine, this instar spins a cocoon that is elaborately decorated with clusters pearly bubbles that are extruded from its anus and then individually attached to the exterior of the cocoon.[2]
