| description |
A strikingly-marked species, unlike anything else in the region. The head, pronotum, and scutellum are a light yellow color; the scutellum may be orange in some individuals. The forewing is light yellow with two dark brown markings that usually form two broad bands: one over the crossveins at the tip of the wings, typically at a noticeably tilt facing inwards and forming an inverted V, and the other around the middle of the clavus and slanting obliquely forward to the coastal margin. Some specimens from the Great Smoky Mountains (TN) also have a longitudinal streak down the clavus that connects these two wings bands (in this case, forming a dark X across the wings), while others from this region only had traces of this longitudinal band. The abdomen has black markings dorsally, the venter is yellow. Adults are 3.75 to 4.0 mm long. (Christian, 1953)

Recently recorded from Mt. Mitchell, likely found elsewhere in high elevation montane regions. |

| comments |
There are two strongly-banded Ossiannilssonola species in eastern North America (O. hinei is also banded but those bands are thin). O. ulmi, which feeds on elm (Ulmus americana, U. rubra, U. fulva) is known from the northeastern United States and southeastern Canada. This species has a different wing pattern, with the anterior brown band transverse rather than oblique (Hamilton, 1982). There is also an (undescribed) species that feeds on Ulmus crassifolia in Texas.
Since specimens of this species from southern Appalachia in TN and now NC have a different wing pattern than individuals in the North, and there are currently no reported specimens between this region and the next closest locales in the Northeastern United States (NY & PA), it could entirely be possible that these populations represent a cryptic, undescribed species. Additional specimens would be needed to determine whether these southern populations are different. |
