Opilidia macrocnema is a species of ground beetle first formally described in 1852 by Maximilien Chaudoir. It is found throughout northern Latin America, ranging from Mexico to Ecuador. [1]

Ground beetle Family of beetles

Ground beetles are a large, cosmopolitan family of beetles, Carabidae, with more than 40,000 species worldwide, around 2,000 of which are found in North America and 2,700 in Europe. It is one of the ten most speciose animal families, as of 2015.

A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species which have been described previously or are related. The species description often contains photographs or other illustrations of the type material and states in which museums it has been deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct.

Maximilien Chaudoir Russian entomologist

Maximilien Chaudoir, or Maximilien, baron de Chaudoir, was a Russian entomologist. He was a specialist in Coleoptera and in particular the Carabidae. His Cicindelidae are conserved by the Muséum national d'histoire naturelle in Paris. His Carabidae were acquired by Charles Oberthür (1845-1924), then given to the same museum. He wrote Mémoire sur la famille des Carabiques, 6 volumes commencing 1848.

Biology

In Costa Rica, adult Opilidia macrocnema obliquans have been found to be active at a temperature range of "20.0-44.9°C and most active at 0800, 1400, and 1500 hours". [2] They have been observed to spend "most of their time on wet sand within one meter of the water line", and can be found hunting small crustaceans, as well as "scavenging omnivorously". [2]

Mount Chirripó mountain in Costa Rica

Mount Chirripó is the highest mountain in Costa Rica with an elevation of 3,821 meters. It is located in Chirripó National Park and is noted for its ecological wealth. The mountain was named "Chirripo," meaning "land of eternal waters", by Native Americans because there are many lakes and streams around the mountain. The high peaks in Chirripó National Park and La Amistad International Park host important areas of Talamancan montane forest and Costa Rican Páramo with high endemism and an extremely high biodiversity. The peaks of these mountains constitute sky islands for many species of plants and animals. Snow has not fallen on the peak in the past 100 years or so, according to the University of Costa Rica, but hail is sometimes reported.

Daniel H. Janzen American biologist

Daniel Hunt Janzen is an American evolutionary ecologist, and conservationist. He divides his time between his professorship in biology at the University of Pennsylvania, where he has been since 1976, and his research and field work in Costa Rica, where he is an ad honorem technical advisor for two long-term and long-range projects, which he conceived and initiated in the early 1970s: Area de Conservación Guanacaste, one of the oldest, largest and most successful habitat restoration project in the world, 1.430 km², located just south of the Costa Rica-Nicaragua border, between the Pacific Ocean and the Cordillera de Tilaran; and the Instituto Nacional de Biodiversidad (INBio), a research organisation that has taken the task of inventorying, cataloguing and describing the country's gigantic natural endowment. He has been influential in the creation of a "model" park, the Area de Conservacion Guanacaste in Costa Rica's northern region of Guanacaste. This park exemplifies Dr. Janzen's beliefs about how a park should be run. It is known for being the site of considerable biological research and for forest restoration and community outreach.

Wildlife of Costa Rica

The Wildlife of Costa Rica comprises all naturally occurring animals, fungi and plants that reside in this Central American country. Costa Rica supports an enormous variety of wildlife, due in large part to its geographic position between the North and South American continents, its neotropical climate, and its wide variety of habitats. Costa Rica is home to more than 500,000 species, which represents nearly 4% of the total species estimated worldwide, making Costa Rica one of the 20 countries with the highest biodiversity in the world. Of these 500,000 species, a little more than 300,000 are insects.

Arenal Volcano National Park is a Costa Rican national park in the central part of the country, forming the Arenal Tilaran Conservation Area. The park encompasses the Arenal Volcano, which "was" the most active in the country, which had previously been believed to be dormant until a major eruption in 1968. It neighbors Lake Arenal, which is the site of the country's largest hydroelectricity project, the Lake Arenal Dam.

Holdridge's toad is a species of toad endemic to Costa Rica. In October 2008, it was declared extinct by the International Union for the Conservation of Nature in its Red List since the species had not been seen since 1987, despite years of extensive searches. However, the species was rediscovered in 2010 by a Costa Rican herpetologist and is now classified as critically endangered. It is believed that the species is most threatened by the presence of the chytrid fungus in its habitat.

Plain chachalaca species of bird

The plain chachalaca is a large bird in the chachalaca, guan and curassow family Cracidae. It breeds in tropical and subtropical environments from mezquital thickets in the Rio Grande Valley in southernmost Texas, United States to northernmost Costa Rica. In Central America, this species occurs in the Pacific lowlands from Chiapas, Mexico to northern Nicaragua and as a separate population in Costa Rica, where its range is separated by a short distance, as a disjunct population.

Costa Rica national cricket team

The Costa Rica national cricket team represents the Republic of Costa Rica in international cricket. The team is organised by the Costa Rica Cricket Federation, which became an affiliate member of the International Cricket Council (ICC) in 2002 and an associate member in 2017. Costa Rica's first recorded international match came in April 2002, when it toured Panama and played against the Panamanian national side. The team's first international tournament was the inaugural edition of the Central American Championships, played in Belize in 2006. It has since regularly fielded teams in that tournament, and also made its debut in ICC Americas tournaments in 2010, at the 2010 Division Four event in Mexico.

Abortion in Costa Rica is severely restricted by criminal law. Currently, abortions are allowed in Costa Rica only in order to preserve the life or physical health of the woman. Abortions are illegal in almost all cases, including when the pregnancy is a result of rape or incest and when the fetus suffers from medical problems or birth defects. Both social and economic factors have led to this legal status. It remains unclear whether abortions are legal to preserve the mental health of the woman, though the 2013 United Nations abortion report says Costa Rica does allow abortions concerning mental health of a woman.

Cinema of Costa Rica refers to the film industry based in Costa Rica. The Costa Rican cinema comprises the art of film and creative movies made within the nation of Costa Rica or by Costa Rican filmmakers abroad.
