Exelastis montischristi

Distinguished from other Exelastis species by geographic distribution and association with host plant Rhynchosia minima. Positive identification requires examination of genitalia or molecular analysis; superficial similarity to other small plume moths in the genus is high.

Small moth with wingspan of approximately 16 millimetres. As a member of Pterophoridae, wings are characteristically divided into feathery plumes. Specific coloration and pattern details are not documented in available sources.

Associated with host plant Rhynchosia minima, a tropical and subtropical legume found in disturbed habitats, grasslands, and open areas. Specific habitat preferences beyond host plant presence are not documented.

Recorded from Hispaniola, Ecuador, Grenada, Jamaica, Martinique, the Virgin Islands, Florida, Texas, and Tanzania. The Tanzanian record represents a notable disjunction from the primarily Neotropical distribution.

Adults have been observed in flight during January, July, and August. Flight period data are sparse and may not represent complete seasonal activity pattern.

Larval feeding is restricted to Rhynchosia minima. Adult feeding habits are not documented.
