Similar Species:
  • Smerinthus cerisyi is mostly absent in western US. The blue ring within the hindwing eyespot tends to be solid, not broken into two arc as is often found in astarte. The forewing tends to have outer margin more deeply scalloped; outer margin of apical white mark more deeply notched; pm. line more jagged, composed of a series of wedge shaped dashes between the veins. In astarte the pm. line tends to forms two smooth outwardly convex arcs with dashes straighter. Intermediate examples exist. Best separated by DNA barcode.
  • Smerinthus ophthalmica is found in British Columbia and west coast states with apparently no overlap.
  • Smerinthus saliceti may be conspecific and, if so, would have priority. If they are separate species, it may be that astarte replaces saliceti north of Mexico. Both names are retained pending further study.
  • Pinned specimens of related species. (Hint: select View by Region on the related species page.)
