The dark palm-dart is a swift-flying organism known for its darting flight pattern, often seen gliding near bamboos, its larval host plant. With compelling agility, adults display an apricot-orange hue on their wings, exhibiting vivid seasonal dimorphism. During the cooler months, they adopt darker, richer colors to absorb sunlight, whereas, in their summer form, lighter tones prevail for heat reflection. This species is a prime study for the relationship between wing coloration and thermoregulation.

Adorning the sunlit clearings and edges of forests, pale palm dart thrives in diverse habitats, from sea level to hilly regions. Its life cycle begins as an inconspicuous ovum, which transforms into a voracious larva feeding on the leaves of various grass species. As an adult, it boasts brilliant orange wings with contrasting black borders, a visual spectacle witnessed during rapid, darting flights as it navigates between nectar sources and mates.

Xenophanes tryxus is a butterfly from the family of the Xenophanes tryxus (Hesperiidae). The scientific name of the species was first validly published in 1780 by Stoll.
