Rectiostoma xanthobasis

[1] It is found along the Atlantic Coastal Plain from south-eastern Massachusetts south to central Florida and eastern Texas, and north in the Mississippi Valley to Missouri and Illinois.

The forewings are dark brown, with lemon yellow triangular area, continuous with a yellow tegula, occupying the basal third except for the short costal lenticular spot and a longer, narrower spot along the posterior wing margin, both spots concolorous with the ground color.

There is a short curved band extending from the distal white area and a submarginal longer straight, iridescent blue violet band parallel to the outer wing margin.

The hindwings are dark brown with a white patch on the basal half of the anterior margin.

They feed from within a shelter constructed of two leaves sandwiched together with silk.
