Description
Adaina desolata is a small moth, typically exhibiting a wingspan of approximately 13 to 17 millimeters. Its forewings and hindwings are generally pale ochreous to brownish-white, often appearing somewhat faded or dusty, which may relate to its specific epithet. Like other plume moths, its wings are deeply lobed, giving them a feathered appearance. The coloration provides effective camouflage against the dry vegetation of its preferred habitats.
Distribution
This species is primarily found in western North America. Its known range includes various states in the United States, such as California, Arizona, New Mexico, Texas, and Colorado, extending southward into Mexico. It thrives in regions characterized by arid or semi-arid climates.
Habitat and Ecology
Adaina desolata inhabits dry, open areas, often in scrublands, deserts, and foothills where its host plants are present. The larvae are phytophagous, meaning they feed on plants.
- Host Plants: The primary known host plant for the larvae of A. desolata is Ageratina occidentalis, commonly known as Western Snakeroot, which belongs to the Asteraceae (sunflower) family. Larvae bore into the flowers and developing seeds of this plant. Other species within the genus Eupatorium (to which Ageratina was formerly often assigned or closely related) may also serve as hosts.
- Life Cycle: The adult moths are typically nocturnal or crepuscular and are attracted to lights. They are usually observed flying during the warmer months, from late spring through early autumn, depending on the specific geographic location and climatic conditions. The larvae develop within the flower heads of their host plants, consuming the reproductive parts.
Etymology
The specific epithet "desolata" is Latin for "desolate" or "abandoned." This name likely refers to the arid, often barren or sparsely vegetated habitats where this moth species is found, or possibly to its somewhat muted, "desolate"-looking coloration.
