California is a state in the Western United States. California borders Oregon to the north, Nevada and Arizona to the east, the Mexican state of Baja California to the south; and has a coastline along the Pacific Ocean to the west. With nearly 39.2 million residents across a total area of approximately 163,696 square miles (423,970 km2), it is the most populous and the third-largest U.S. state by area. It is also the most populated subnational entity in North America and the 34th most populous in the world. The Greater Los Angeles area and the San Francisco Bay Area are the nation's second and fifth most populous urban regions respectively, with the former having more than 18.7 million residents and the latter having over 9.6 million. Sacramento is the state's capital, while Los Angeles is the most populous city in the state and the second most populous city in the country. Los Angeles County is the country's most populous, while San Bernardino County is the largest county by area in the country. San Francisco, which is both a city and a county, is the second most densely populated major city in the country and the fifth most densely populated county in the country, behind four of New York City's five boroughs.
The Gulf of California, also known as the Sea of Cortés or Sea of Cortez, or less commonly as the Vermilion Sea, is a marginal sea of the Pacific Ocean that separates the Baja California Peninsula from the Mexican mainland. It is bordered by the states of Baja California, Baja California Sur, Sonora, and Sinaloa with a coastline of approximately 4,000 km (2,500 mi). Rivers that flow into the Gulf of California include the Colorado, Fuerte, Mayo, Sinaloa, Sonora, and the Yaqui. The surface of the gulf is about 160,000 km2 (62,000 sq mi). Maximum depths exceed 3,000 meters (9,800 ft) because of the complex geology, linked to plate tectonics.
Baja California, officially the Free and Sovereign State of Baja California is a state in Mexico. It is the northernmost and westernmost of the 32 federal entities of Mexico. Before becoming a state in 1952, the area was known as the North Territory of Baja California. It has an area of 70,113 km2 (27,071 sq mi) and comprises the northern half of the Baja California Peninsula, north of the 28th parallel, plus oceanic Guadalupe Island. The mainland portion of the state is bordered on the west by the Pacific Ocean; on the east by Sonora, the U.S. state of Arizona, and the Gulf of California; on the north by the U.S. state of California; and on the south by Baja California Sur.
Baja California Sur, officially the Free and Sovereign State of Baja California Sur, is the least populated state and the 31st admitted state of the 32 federal entities which comprise the 31 States of Mexico. It is also the ninth-largest Mexican state in terms of area.
The Gelechiidae are a family of moths commonly referred to as twirler moths or gelechiid moths. They are the namesake family of the huge and little-studied superfamily Gelechioidea, and the family's taxonomy has been subject to considerable dispute. These are generally very small moths with narrow, fringed wings. The larvae of most species feed internally on various parts of their host plants, sometimes causing galls. Douglas-fir (Pseudotsuga) is a host plant common to many species of the family, particularly of the genus Chionodes, which as a result is more diverse in North America than usual for Gelechioidea.
The green-tailed towhee is the smallest towhee, but is still one of the larger members of the American sparrow family Passerellidae.
Aridoamerica denotes an ecological region spanning Northern Mexico and the Southwestern United States, defined by the presence of the culturally significant staple foodstuff Phaseolus acutifolius, a drought-resistant bean. Its dry, arid climate and geography stand in contrast to the verdant Mesoamerica of present-day central Mexico into Central America to the south and east, and the higher, milder "island" of Oasisamerica to the north. Aridoamerica overlaps with both.
Megacraspedus is a genus of moths in the family Gelechiidae, found primarily in the Palearctic.
Monochroa is a genus of moths in the family Gelechiidae.
Neopalpa is a genus of moths in the family Gelechiidae. They are found in California, Arizona, and northern Mexico. Neopalpa is classified in the tribe Gnorimoschemini and is most closely related to the genera Ochrodia and Ephysteris.
Keiferia lycopersicella, the tomato pinworm, is a moth of the family Gelechiidae. It is found in warm areas in Mexico, California, Texas, Georgia, Florida, Hawaii, Cuba, Hispaniola and the Bahamas. It has also been reported from greenhouses in Delaware, Mississippi, Missouri, Pennsylvania and Virginia.
Gelechiinae is a subfamily of moths in the family Gelechiidae. It was described by Henry Tibbats Stainton in 1854.
Aroga unifasciella is a moth of the family Gelechiidae. It is found in North America, where it has been recorded from Montana south to western New Mexico, west through Arizona to eastern and southern California.
Aroga paulella is a moth of the family Gelechiidae. It is found in North America, where it has been recorded from Arizona, California, Colorado, Kansas, New Mexico, Texas and Wyoming.
Friseria cockerelli, the mesquite webworm moth, is a moth of the family Gelechiidae. It is found in Mexico and the southern United States, where it has been recorded from Texas, New Mexico, Arizona, Colorado, California, Oklahoma and Nevada.
Neopalpa donaldtrumpi is a moth species of the genus Neopalpa occurring in Southern California and Northern Mexico. It was described in 2017 by Iranian-Canadian scientist Vazrick Nazari. Known for its yellowish-white head scales being reminiscent of Donald Trump's hair, the moth was given its name because Nazari stated that he wanted "to bring wider public attention to the need to continue protecting fragile habitats in the US that still contain many undescribed species."
Ronald William Hodges, known as Ron, was an American entomologist and lepidopterist.
