My identification of Eccritothrix trimaculella is based on comparison with photographs on the web site "All Leps Barcode of Life" at http://www.lepbarcoding.org/index.php and on the description of this species in Forbes, William T.M., The Lepidoptera of New York and Neighboring States, Primitive Forms, Microlepidoptera, Pyraloids, Bombyces (Ithaca, New York: Cornell University, 1923).

Eccritothrix trimaculella has straw-yellow to buff forewing with brownish gray and black markings.  There is a brownish gray shade along the inner half of the costa, darker near the base.  The wing has three distinctive black spots.  The spot closest to the inner margin, about midway along the wing is slightly elongated; the other two spots are more or less round, the outermost one being significantly larger.  The terminal line is a series of dark brownish gray dots, and there are several short inward streaks of gray.  There is also slight gray-brown dusting or speckling on the wing.  Forbes (1923) indicates a wingspan of 12 mm.

According to Forbes (1923), the adult Eccritothrix trimaculella flies in July.  He gives no information as to host plants or life history.

My only record to date for Eccritothrix trimaculella (each date representing "the night of") is in the table below:
