Synonyms and other taxonomic changes
Acrolophus texanella (Chambers, 1878)
Anaphora texanella Chambers, 1878
Acrolophus hulstellus, (Beutenmüller, 1887)
A. barnesii, (Dyar, 1900)
♀ 24 mm.
♂ 20 mm.

Adult: Head fuscous. Labial palps re-curved over the head. Apical portion of the FW is darker brown, separated by whitish oblique patch, running from the discal cell toward the anal angle. Female is similar, except labial palps are short and not erect. The oblique patch is larger and more suffused. [adapted from Beutenmüller's original description of Acrolophus hulstellus]
Chambers (1878) original description as Anaphora texanella is available online in the print references.

Structurally, palps are similar to walsinghami, popeanella, and propinqua, but the wing pattern when fresh is usually distinctive: a “stripe” runs from the middle of the costa diagonally to the anal angle in both females (left) and males (right):

The wings are darker distal this stripe. The wing itself is actually creased along this stripe as well, so even in worn or poorly marked individuals, the “stripe” can be seen in the form of a wing crease, like in these:

Melanic individuals, like the right one shown above, often have a few white scales along the crease. White scaling occurs on several other Acrolophus when fresh as well.
Heppner (2003) listed the range as Maryland to Florida, Illinois to Texas. (1), (2), (3), (4), (5)
Like mortipennella, mostly a species of the Midwest and Southeast, rare to absent in the Northeast.
Adults are most common from May to October. (6)
Heppner (2003) reported adults from April to December in Florida. (5)
Heppner (2003) listed the larval host plant as grass (Gramineae). (5)
