Identification
Miraces can be distinguished from other skeletonizing leaf beetles by their characteristic feeding damage pattern on leaves, though specific morphological diagnostic features for the require examination of specimens. The six described species within the genus are distinguished primarily by subtle differences in coloration, body proportions, and male genitalia. Accurate identification to species level generally requires examination and comparison with .

Distribution
North America and the Neotropics. The has been documented from the United States southward through Mexico and into Central and South America.
Behavior
are known as skeletonizing leaf beetles, feeding on leaf tissue between the while leaving the vascular network intact. This produces a characteristic lace-like appearance on damaged leaves.
Ecological Role
As herbivores, these beetles function as primary consumers in their . Their skeletonizing feeding may influence plant physiology and leaf longevity, though specific ecological impacts have not been quantified.

Taxonomic history
The was described by Martin Jacoby in 1888, with Miraces aeneipennis as the type . The genus has remained relatively small, with only six described species recognized over more than 130 years of study.
Species diversity
The six described are: M. aeneipennis Jacoby, 1888; M. barberi (Blake, 1951); M. dichroa (Suffrian, 1868); M. glaber (Blake, 1946); M. modesta (Horn, 1893); and M. placida (Horn, 1893). Several species were originally described in other and later transferred to Miraces.
