Bucculatrix coronatella

Clemens, 1860

Larval feeding type: leaf-miner initially, then feeding externally
Larval substrate: Betula nigra (River Birch), B. populifolia* (Gray Birch)
Phenology: Adult: 5/10 to 8/19 (10 records)

Comment: Similar to B. canadensisella, also a birch feeder, but is generally brighter orange-brown and it lacks the white forewing base (but is paler). The white markings are generally weak against the bright ground color. The first costal streak is narrowly interrupted with ground color on the costa and the area behind the raised scales is not dark. This species is also very similar to B. improvisa, a Basswood feeder, and some specimens reported from MA as B. coronatella may in fact be that species. Also similar to B. trifasciella, which should have silvery markings, but often they are more whitish and it can then be confused with this species.
