Hodges Number
Possibly mistaken for Filatima biminimaculella (of which see BugGuide photo 364610 for a good example), from which it can be differentiated via the following particulars: in Fascista bimaculella, (1) Ground color of forewing uniformly dark gray (versus darker on either side of the central white spot in Filatima biminimaculella); (2) White patch near base of forewing absent (versus present); (3) Dorsum of prothorax dark gray (versus contrastingly ochreous); (4) Head dark gray (versus white or whitish).
Midwestern USA; common in Illinois and Kentucky; also recorded from Colorado.
Sometimes common in light-trap samples from tallgrass prairie, but also collected at light in other plant communities. Based on its morphological structure, it does appear to be closely related to the redbud leaffolder, Fascista cercerisella, which is a tree feeder. Being a gelechiid, F. bimaculella probably is hostplant specific. Rearing is needed, to assess its biotic affinities. Who among us will be the first to figure out and make known its life history?
Records of adults collected at light indicate general summer occurrence.
