Eucosma knudsoni
Wright & Gilligan, 2015
Eucosma knudsoni is a of tortricid described from Texas in 2015. It belongs to a large of small moths commonly known as bell moths or eucosmas, many of which are associated with Asteraceae plants. The species is known from very few observations, reflecting both its recent description and likely restricted distribution or cryptic habits. As a member of the Olethreutinae , it possesses the characteristic tortricid resting posture with wings held rooflike over the body.

Identification
Eucosma knudsoni can be distinguished from by genitalic characters as described in the original description. Specific external morphological features separating it from similar Eucosma species in the region have not been published in accessible sources. Identification to species level requires examination of male genitalia, specifically the valvae and structure. The species is smaller than many related Eucosma species, though precise measurements are not widely available.
Distribution
Known from Texas, USA, based on the type locality. The precise collection locality was not specified in widely available sources. Additional distribution records have not been published.
Similar Taxa
- EucosmaMultiple Eucosma occur in Texas and the southwestern United States. E. knudsoni requires genitalic dissection for reliable identification; external appearance alone is insufficient to distinguish it from sympatric such as E. giganteana or E. bobana.
