(Chambers, 1872)
Redbud Leaffolder Moth, redbud leaffolder
Fascista cercerisella, commonly known as the redbud leaffolder , is a small moth to eastern and central North America. The is notable for its specialized larval association with eastern redbud (Cercis canadensis), where leaves by feeding within folded leaf structures. are active from spring through fall, with geographic variation in time— in northern and possibly in the south.

Identification
are small (13–16 mm wingspan) requiring dissection or genital examination for definitive identification. are more readily identified by their distinctive zebra-striped appearance and association with folded leaves of eastern redbud (Cercis canadensis). The combination of specificity and larval shelter-building distinguishes this from other leaf-folding .

Behavior
construct leaf folds or rolls on foliage, feeding within these shelters and skeletonizing the leaf tissue. This shelter-building gives the its 'leaffolder'.
Ecological Role
specializing on eastern redbud foliage; specific functions not documented.
Human Relevance
Minor pest of ornamental eastern redbud trees due to leaf damage caused by larval feeding; not considered economically significant.
