Adult - Base color generally tan and dark brown-tan (males) and orange-tan (females). FW apex falcate. AM and PM lines brown; PM line narrow, sinuate, sometimes with very narrowpale outer edge, bending basad at vein M3; MB colored as rest of wing, often with a diffuse darker central patch; submarginal area dark diffuse banding frequently present. Additional patchy markings may be present producing a dead-leaf aspect. DHW with poorly-developed median line that fades out toward upper margin. Dark discal spots on FW and HW. Ventrally paler with dorsal markings repeated; wing surfaces with widelyscattered dark scales suggesting a dead-leaf pattern.

About Butterflies and Moths: the wider group

Order-level background for Lepidoptera, the group containing Tetracis jubararia. 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.
