In polymer chemistry and materials science, a resin is a solid or highly viscous substance of plant or synthetic origin that is typically convertible into polymers. Resins are usually mixtures of organic compounds. This article focuses mainly on naturally occurring resins.
Enterolobium cyclocarpum, commonly known as conacaste, guanacaste, caro caro, devil's ear tree, monkey-ear tree, or elephant-ear tree, is a species of flowering tree in the family Fabaceae, that is native to tropical regions of the Americas, from central Mexico south to northern Brazil (Roraima) and Venezuela. It is known for its large proportions, expansive, often spherical crown, and curiously shaped seedpods. The abundance of this tree, especially in Guanacaste Province, Costa Rica, where it is prized for the shady relief it provides from the intense sun, coupled with its immensity, have made it a widely recognized species. It is the national tree of Costa Rica.
Hymenaea is a genus of plants in the legume family Fabaceae. Of the fourteen living species in the genus, all but one are native to the tropics of the Americas, with one additional species on the east coast of Africa. Some authors place the African species in a separate monotypic genus, Trachylobium. In the Neotropics, Hymenaea is distributed through the Caribbean islands, and from southern Mexico to Brazil. Linnaeus named the genus in 1753 in Species Plantarum for Hymenaios, the Greek god of marriage ceremonies. The name is a reference to the paired leaflets.
Belostomatidae is a family of freshwater hemipteran insects known as giant water bugs or colloquially as toe-biters, Indian toe-biters, electric-light bugs, alligator ticks, or alligator fleas. They are the largest insects in the order Hemiptera. There are about 170 species found in freshwater habitats worldwide, with more than 110 in the Neotropics, more than 20 in Africa, almost as many in the Nearctic, and far fewer elsewhere. These predators are typically encountered in freshwater ponds, marshes and slow-flowing streams. Most species are at least 2 cm (0.8 in) long, although smaller species, down to 0.9 cm (0.35 in), also exist. The largest are members of the genus Lethocerus, which can exceed 12 cm (4.5 in) and nearly reach the length of some of the largest beetles in the world. Giant water bugs are a popular food in parts of Asia.
The family Fulgoridae is a large group of hemipteran insects, especially abundant and diverse in the tropics, containing over 125 genera worldwide. They are mostly of moderate to large size, many with a superficial resemblance to Lepidoptera due to their brilliant and varied coloration. Various genera and species are sometimes referred to as lanternflies or lanthorn flies, though they do not emit light.
Honeydew is a sugar-rich sticky liquid, secreted by aphids, some scale insects, and many other true bugs and some other insects as they feed on plant sap. When their mouthpart penetrates the phloem, the sugary, high-pressure liquid is forced out of the anus of the insects, allowing them to rapidly process the large volume of sap required to extract essential nutrients present at low concentrations. Honeydew is particularly common as a secretion in hemipteran insects and is often the basis for trophobiosis. Some caterpillars of Lycaenidae butterflies and some moths also produce honeydew. In addition to various sugars, honeydew contains small amounts of amino acids, other organic compounds, and inorganic salts with its precise makeup affected by factors such as insect species, host plant species, and whether a symbiotic organism is present.
The silver-throated tanager is a species of passerine bird in the tanager family Thraupidae. It is found in Costa Rica, Panama, Colombia, Ecuador, and northeastern Peru. It inhabits mossy forests, montane evergreen forests, tropical lowland evergreen forests and forest edges, along with tall secondary forests and disturbed habitat with remnant trees and forest. It is 13 centimetres (5.1 in) long and weighs 22 grams (0.78 oz) on average, and shows slight sexual dimorphism, with duller female plumage. Adult males are mainly bright yellow, with a silvery-white throat bordered above with a black stripe on the cheeks, black streaking on the back, and green edges to the wings and tail. Juveniles are duller and greener.
Hymenaea courbaril, the courbaril or West Indian locust, is a tree common in the Caribbean, Central America, and South America. It is a hardwood that is used for furniture, flooring, and decoration. Its hard fruit pods have edible dry pulp surrounding the seeds. Its sap, called animé, is used for incense, perfume, and varnish.
Jadera haematoloma, the red-shouldered bug, goldenrain-tree bug or soapberry bug is a species of true bug that lives throughout the United States and south to northern South America. It feeds on seeds within the soapberry plant family, Sapindaceae, and is known to rapidly adapt to feeding on particular hosts. The species is often confused with boxelder bugs and lovebugs.
Pyrops candelaria is a species of planthopper often placed in the tribe Laternariini. This species has been recorded from: Guangdong, Guangxi, Cambodia, Vietnam, Hong Kong, Laos, Thailand and other parts of southeast Asia. It is the type of the genus Pyrops erected by Spinola in 1839.
The fulgorid genus Fulgora contains several large Central and South American planthoppers known by a large variety of common names including lantern fly, peanut bug, peanut-headed lanternfly, alligator bug, machaca, and jequitiranaboia.
Pyrops is a genus of planthoppers that occur primarily in southeast Asia, containing about 70 species. They are fairly large insects, with much of the length due to an elongated, upcurving, snout-like projection of the head. The wings are generally brightly patterned in contrasting colors, and they are popular among collectors.
Triatoma dominicana is an extinct species of assassin bug in the subfamily Triatominae, the kissing bugs known from early Miocene Burdigalian stage Dominican amber deposits on the island of Hispaniola.
Enchophora sanguinea is a species of lantern bug, a type of hemipteran, found in Central and South America. It was first described by William Lucas Distant in 1887. They are 25 millimetres (1.0 in) long. Their colour varies, but is normally red to green; they have a scimitar-shaped process on their heads. They feed on the sap of trees, most commonly Simarouba amara, and they excrete honeydew out of their anuses.
Pittieria aurantiaca is a species of predatory air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Spiraxidae.
Paracoccus marginatus, commonly known as the papaya mealybug, is a small sap-sucking insect in the mealybug family, Pseudococcidae. It is found on a number of different hosts, including economically important tropical fruit trees and various ornamental plants.
Apterostigma eowilsoni is an extinct species of ant in the subfamily Myrmicinae known from a single possibly Miocene fossil found on Hispaniola. A. eowilsoni is one of only two species of the ant genus Apterostigma and one of five attini species of to have been described from fossils found in Dominican amber.
Pyrops coelestinus, previously known as Laternaria coelestina, is a species of planthopper belonging to a genus referred-to as lantern-bugs, sometimes known as the blue lantern bug.
Agalmatium flavescens is a species of planthopper belonging to the family Issidae, subfamily Issinae.
Winifred Hallwachs is an American tropical ecologist who helped to establish and expand northwestern Costa Rica's Área de Conservación Guanacaste (ACG). The work of Hallwachs and her husband Daniel Janzen at ACG is considered an exemplar of inclusive conservation.
