This is a highly polymorphic species. According to Powell (1964), California specimens usually have uniform brown, black, or dull red forewings with a gray basal band. Males lack a forewing costal fold.
Related or similar species
Acleris hastiana may appear similar to other species of Acleris due to its highly variable forewing pattern.
A. hastiana completes two generations per year in California. Adults are active in June and July and again in August through October.
First instar larvae bore into buds. Later intars feed within shelters constructed by webbing together terminal leaves. Pupation occurs within the larval shelter or on the ground.
In North America hastiana has been recorded feeding on blueberry (Vaccinium sp.), bog rosemary (Andromeda sp.), Ceanothus sp., huckleberry (Gaylussacia sp.), oak (Quercus sp.), Rhododendron sp., and willow (Salix sp.).
