Species Ormenoides venusta

Ormenoides pauperata (Melichar 1902)(1)(2)

Ormenoides venusta (Melichar 1902)

The only unmarked flatid in e. US with wing crossveins almost completely random - only a single row of them parallels the wing edge. Wings are narrower at the tip than in Anormenis and without a prominent double row of crossveins that traverse the wing. The orange edges to the wings are distinctive. In nymphs, the orange spots and 4-6 black tail spots are distinctive. (Dr Hamilton)

polyphagous(1); Often found on wild grape

Ormenoides may occur in large numbers, but do little apparent damage and have not been directly implicated in plant disease transmission (although this has not been excluded either). (1)

Among eastern flatids, Ormenoides venusta is smaller than Flatormenis proxima, and tends to have a brownish or orangish border on the wings. (1) Wingtips are more rounded in Ormenoides venusta (below, left). Wingtips in Flatormenis proxima are more angular (below, right):
