Eucalantica
Busck, 1904
Species Guides
1Eucalantica is a of micro- in the Yponomeutidae, first described by Busck in 1904. The genus was long considered , known only from a single Nearctic , until a 2011 taxonomic review described six new species from Central America and southern North America. Members of this genus are characterized by silvery white coloration with distinctive dark brown costal streaks on the forewings. Yponomeutid moths, including Eucalantica, are considered important for understanding the evolution of plant associations in Lepidoptera.

Identification
Distinguished from the superficially similar Thecobathra by the presence of a dark brown costal streak on the forewing; Thecobathra lacks this streak. The resting posture—body parallel to substrate with forelegs extended forward—may also aid identification. Genus-level identification requires examination of wing pattern and resting posture.
Appearance
Small with silvery white body and forewings. Forewings bear a distinctive dark brown costal streak. Overall coloration is pale and reflective. When at rest, the body is held parallel to the substrate with forelegs extended forward.
Habitat
Tropical highlands of Central America; also occurs in southern USA and Mexico. Specific microhabitat preferences are not documented.
Distribution
Rica (five : E. costaricae, E. ehecatlella, E. icarusella, E. powelli, E. pumila); southern USA and Mexico (E. vaquero). Previously known only from Nearctic region before 2011 revision.
Behavior
Rests with body held parallel to the substrate and forelegs extended forward.

Taxonomic History
The was long considered , with only one Nearctic known, until a 2011 revision by Sohn and Nishida described six new species, demonstrating significantly underestimated diversity in Neotropical yponomeutids.
Systematic Importance
Yponomeutid , including Eucalantica, are considered important for tracing the evolution of plant association in Lepidoptera, though the 's biodiversity and remain poorly understood.
