Cheek
The cheek is inflated in the same way as that in the thumbed image. This might be Scambus, but the small size and the elongation of the areolet seem a bit anomalous. Alophosternum foliicola Cushman is a small species with an elongate areolet that has been reared from leaf-mining sawflies and microleps, including one species of Cameraria, but the face, frons, scape, cheek, etc. are white in males. According to TaxaPad, Scambus decorus Walley has also been reared from a species of Cameraria. That is a rather small species of Scambus (front wing 2.5 to 4.2 mm), but Walley says the front coxa is mostly black in males. Scambus inanis (Schrank) has also been recorded from Cameraria but apparently not in North America. That species was misidentified as Scambus nucum (Ratzeburg) by Walley (1960). Walley said that the hind coxa is usually black in that species. For some species of Scambus, the shape of the underside of the front femur is diagnostic.
