Dejongia californicus
This record describes Dejongia californicus (species). Recorded family: Pterophoridae. Recorded order: Lepidoptera.
Identification and Appearance

See the identification key for Oxyptilini . See the species accounts in Matthews et al. and Barnes & Lindsey as Trichoptilus californicus . Dejongia californicus adults have: a forewing second lobe that is narrow with an acute apex, as in Buckleria , Dejongia lobidactylus , Trichoptilus , and Megalorhipida , and not broader with a well developed, curved outer margin, as in Sphenarches , Geina , Capperia , and Oxyptilus . antennae with longitudinal brown and white lines, as in Megalorhipida leucodactylus and unlike in Dejongia lobidactylus and Trichoptilus . diverging, disconnected, white subdorsal lines on abdominal segments two and three, extending across nearly the whole of both segments, and usually obsolete on segment 4, unlike in Dejongia lobidactylus (white subdorsal lines of segment three extended across only the posterior 1/2 to 2/3 of segment), unlike in Buckleria parvulus (continuous, white subdorsal lines across most segments, including segment four), and unlike in Trichoptilus (no conspicuous subdorsal lines). no white middorsal line on the abdomen, which is often present in Megalorhipida leucodactylus .

About Butterflies and Moths: the wider group
Order-level background for Lepidoptera, the group containing Dejongia californicus. 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.
