FeatureDescription
Additional detailsXestia finatimis looks like a pale gray washed out form of Xestia infimatis .
ForewingForewing gray or brownish gray, usually with longitudinal brown streak distal to reniform spot; AM line dark gray and deeply zigzagged but inconspicuous due to blending in with dark-gray shading of veins; PM line deeply scalloped but inconspicuous with only small black dot at apex of scallops somewhat prominent; reniform spot rectangular, lower proximal corner stretches slightly toward wing base, filled with dark-gray with pale outline; orbicular spot oblique, elongate, almost bar-like, extending from costa to reniform spot, filled with pale gray, dark central bar in some specimens; claviform spot shows as elongate pale-gray filled loop; prominent black basal dash ends near claviform spot; ST area with series of dark gray-brown streaks that tend to fuse into triangular patch distal to reniform spot, similar smaller patch distal to claviform spot; terminal line black, deeply scalloped.
HindwingHindwing pale smoky gray brown, slightly darker on discal spot, median line and outer one-fourth of wing; terminal line dark brown, interrupted at veins; fringe pale gray. Description of genitalia available in MONA Fascicle 27-3 available at link under citations below. Genitalia:

About Butterflies and Moths: the wider group

Order-level background for Lepidoptera, the group containing Xestia finatimis. Species-specific details appear above.

Group overview

Lepidoptera includes approximately 180,000 described species of butterflies and moths. Moths outnumber butterflies roughly 10:1. The monarch butterfly's eastern population has declined by more than 80% since the mid-1990s, and the western population by over 95% since the 1980s. The IUCN lists the migratory monarch as Vulnerable.

Ecological role of the group

Butterflies and moths are essential indicators of ecosystem health. As caterpillars, they are a primary food source for birds - a single nest of blue tit chicks requires ~10,000 caterpillars. Adult moths pollinate many night-blooming plants.

Economic and practical significance of the group

Lepidoptera are critical pollinators. In Europe, grassland butterfly species have declined by almost 50% since the early 1990s. In the UK, three-quarters of butterflies are in decline. In the U.S., five butterfly species have gone extinct since 1950, with 29 listed as endangered.

Recorded sources for this group: IUCN Red List, Xerces Society, USFWS, PNAS, WWF. Imported estimates may describe particular regions or reporting periods.
