| Adult Markings: This species is very similar to Ecdytolopha insiticiana but lacks the black patch in the subtornal region. The palps and antennae are brown and the head tuft brownish black. The thorax is mottled with brown and black and has a blackish scale tuft on the posterior half. The basal half of the forewing is dark brown to grayish brown with fine blackish mottling. The dark coloration extends from the base to about mid-way on the inner margin, then slants posteriorly towards the costal margin and adjoins a pronounced pale dirty white region that covers much of the remainder of the forewing. The whitish region has a small, irregular, and often faint black patch at around three-fourths near the middle of the wing, along with a rather faint and slightly curved dark brown to blackish streak at around four-fifths that extends from above the costal margin to the subapical region near the mid-point of the termen. The fringe is grayish to grayish-white and there is a series of basal black dots that extend from near the apex to the middle of the termen. The hindwing is uniformly grayish-brown to brown with a paler fringe that has a narrow dark brown basal line. |

| Adult ID Requirements: Identifiable from good quality photos of unworn specimens. |
| Immatures and Development: The larvae appear to specialize on hackberries (Celtis spp.; MacKay 1959; Brown 2022), but most aspects of the larval life history are poorly documented. Limited evidence indicate that the larvae feed within leaf galls or petiole galls on the trees. |
