About Bastilla arctotaenia
This moth species has a wingspan of approximately 52 millimeters. While it resembles the related species Bastilla arcuata, it can be distinguished by a key difference: the postmedial line of its forewings is distinctly white from the costa to the angle at vein 6. Its medial white band is always well-defined, narrow, and nearly uniform in width across its entire length. The larvae are elongated, slender semi-loopers. They are greyish brown in overall color, with a speckled head. A pair of black spots can be seen marking the species' small larval tubercles. Known host plants for the larvae include species from the genera Quercus, Ricinus, Rosa, and Salix. Adult moths of this species act as fruit piercers.
