See the identification key for Oxyptilini . See the species accounts in Landry , Landry , and McDunnough as Pterophorus ontario . Sphenarches ontario adults have: a forewing second lobe that is broader with a well developed, curved outer margin, as in Sphenarches anisodactylus , Geina , Capperia , and Oxyptilus , rather than narrow with an acute apex, as in Buckleria , Dejongia , Trichoptilus , and Megalorhipida . a brown and unmarked abdominal segment four, as in Geina , and unlike in Capperia and Oxyptilus . a mostly brown metathorax, as in Geina periscelidactylus and G. sheppardi , rather than the metathorax having large, white lateral patches, as in Geina tenuidactylus and G. buscki , or having white lines on the metathorax and and on the mesothorax connecting the white tegulae, as in Sphenarches anisodactylus , Oxyptilus delawaricus , and Capperia . tawny brown ground color in the wings and abdomen, as in Geina periscleidactylus and G. sheppardi and Oxyptilus delawaricus , unlike the darker, chocolate brown ground color of Geina tenuidactylus , G. buscki , and Capperia . a dark triangular patch before the cleft base, unlike the dark, transverse line before the cleft base in Geina periscelidactylus and G. sheppardi . a dark scale tooth well developed in both the costal and dorsal fringes of the hindwing third lobe, as in Geina , and unlike in Sphenarches anisodactylus (dark scale tooth developed mostly in dorsal fringe).

About Butterflies and Moths: the wider group

Order-level background for Lepidoptera, the group containing Sphenarches ontario. 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.
