Amitermes floridensis, commonly known as the Florida darkwinged subterranean termite, [2] is a species of eusocial insect in the family Termitidae. It feeds on rotting wood, reached by a network of tunnels. It is endemic to west central Florida and was first described in 1989.
During a survey of termites in Florida in the late twentieth century, a few winged specimens of an unidentified dark-winged termite in the family Termitidae were seen. This family contains around 1600 species but none had previously been found in the eastern United States. In 1988, swarms of these dark-winged termites were seen near the original location and further searches enabled workers of this species to be identified. The species was formally described in 1989 by the Florida entomologists Scheffrahn, Su, and Mangold; they named the new species Amitermes floridensis because it seemed to be restricted to the state of Florida. [3]
Workers are up to 3.5 mm (0.14 in) long. The thorax is constricted and the abdomen inflated, giving them a plump appearance. The head capsule is colourless and the abdomen transparent, so that the gut and its contents can be seen through the cuticle, giving them an overall greyish-colour. Soldiers are a similar size but the larger head capsule is pigmented and armed with black, crescent-shaped mandibles, each with a distinctive tooth on its inner surface. Nymphs develop in mature colonies during the spring; these are larger than the workers, have wider thoraxes and have wing pads. These develop into alates, winged males and females, which are dark brown, with bodies 4 mm (0.16 in) long and a total length with wings of 9 mm (0.35 in). The wings are slender, with dark veins on the leading edge. The queen and king live deep below the ground but have not been observed in this species. [2]
The Florida darkwinged subterranean termite has only been found in west central Florida, particularly around St. Petersburg. Its range extends from Tarpon Springs in the north to Sebring in the east and Punta Gorda in the south. It lives in an underground colony with extensive foraging passages. Where these emerge onto the surface in feeding locations, the above-ground portions are quite short. [2]
The termite colony has subterranean chambers and extensive underground foraging passages, rotting timber being the main diet. This species does not form galleries inside timber, but forms tubes along the surface, grazing on the wood, but not rising far above the ground. These tubes have faecal matter incorporated into them and are black. Structures attacked include fallen logs, fence posts, tree trunks, sheds and porches. [2]
Winged reproductives emerge from the nest through special free-standing short "swarm tubes" during the day between July and September. Swarms often occur soon after rainfall, or even before the rain has stopped; the numbers of insects can be very large, resembling columns of smoke issuing from the ground. [2] The insects are weak fliers and many get stuck to wet foliage, buildings or vehicles. [2] Those that return to the ground form pairs and the female searches out a suitable location under a log, stone or debris, in which to start a colony. It may take several years before a colony is large enough to produce its own alates. [2] [4]
Termites are a group of detritophagous eusocial insects which consume a wide variety of decaying plant material, generally in the form of wood, leaf litter, and soil humus. They are distinguished by their moniliform antennae and the soft-bodied and typically unpigmented worker caste for which they have been commonly termed "white ants"; however, they are not ants, to which they are distantly related. About 2,972 extant species are currently described, 2,105 of which are members of the family Termitidae.
Reticulitermes flavipes, the eastern subterranean termite, is the most common termite found in North America. These termites are the most economically important wood destroying insects in the United States and are classified as pests. They feed on cellulose material such as the structural wood in buildings, wooden fixtures, paper, books, and cotton. A mature colony can range from 20,000 workers to as high as 5 million workers and the primary queen of the colony lays 5,000 to 10,000 eggs per year to add to this total.
The green-head ant, also known as the green ant or metallic pony ant, is a species of ant that is endemic to Australia. It was described by British entomologist Frederick Smith in 1858 as a member of the genus Rhytidoponera in the subfamily Ectatomminae. These ants measure between 5 and 7 mm. The queens and workers look similar, differing only in size, with the males being the smallest. They are well known for their distinctive metallic appearance, which varies from green to purple or even reddish-violet. Among the most widespread of all insects in Australia, green-head ants are found in almost every Australian state, but are absent in Tasmania. They have also been introduced in New Zealand, where several populations have been established.
Nasutitermes corniger is a species of arboreal termite that is endemic to the neotropics. It is very closely related to Nasutitermes ephratae. The species has been studied relatively intensively, particularly on Barro Colorado Island, Panama. These studies and others have shown that the termite interacts with many different organisms including a bat that roosts in its nest and various species of ants that cohabit with the termite.
Kalotermitidae is a family of termites, commonly known as drywood termites. Kalotermitidae includes 21 genera and 419 species. The family has a cosmopolitan circumtropical distribution, and is found in functionally arid environments.
Coptotermes gestroi, commonly known as the Asian subterranean termite is a small species of termite that lives underground. Both this species and the Formosan subterranean termite are destructive pests native to Asia, but have spread to other parts of the world including the United States. In Asia, this species is known as the Philippine milk termite.
The Hodotermitidae are a basal Old World family of termites known as the harvester termites. They are distinguished by the serrated inner edge of their mandibles, and their functional compound eyes which are present in all castes. They forage for grass at night and during daylight hours, and the pigmented workers are often observed outside the nest. Their range includes the deserts and savannas of Africa, the Middle East, and Southwest Asia. Their English name refers to their habit of collecting grass, which is not unique to the family however.
Hodotermes is a genus of African harvester termites in the Hodotermitidae. They range from Palaearctic North Africa, through the East African savannas to the karroid regions of southern Africa. As with harvester termites in general, they have serrated inner edges to their mandibles, and all castes have functional compound eyes. They forage for grass at night and during the day, and their pigmented workers are often observed outside the nest.
Incisitermes minor is a species of termite in the family Kalotermitidae known commonly as the western drywood termite. It is native to western North America, including the western United States and northern Mexico. It has been found in many other parts of the United States, all the way to the East Coast. It has been reported from Toronto. It has been introduced to Hawaii. It has been noted in China and it is not uncommon in Japan. This is an economically important pest of wooden structures, including houses. In California and Arizona alone its economic impact is estimated to be about $250 million per year.
Amitermes is a genus of termites in the family Termitidae. It is the second largest genus after Microcerotermes in the subfamily Amitermitinae with around one hundred species. Species are found in a range of habitats including deserts and rainforests. Characteristics of Amitermes soldiers include a bulbous head, sickle-shaped mandibles with a single tooth on their inner margins and cephalic glands on the front of their heads.
Cryptotermes brevis is a species of termite in the family Kalotermitidae, commonly known as the West Indian drywood termite or the powderpost termite. It is able to live completely inside timber structures or articles made of wood such as furniture without any outside source of water. It is frequently introduced into new locations inadvertently, and causes damage to the structural timbers of buildings and to wooden objects such as furniture.
Macrotermes carbonarius, also known as Kongkiak in Malay, is a large black species of fungus-growing termite in the genus Macrotermes. It is one of the most conspicuous species of Macrotermes found in the Indomalayan tropics, forming large foraging trails in the open that can extend several metres in distance. M. carbonarius is a highly aggressive species with the soldiers possessing large curving mandibles that easily break skin. It is found in Cambodia, Malaysia, Myanmar, Singapore, Thailand and Vietnam.
Amitermes hastatus, commonly known as the black mound termite, is a species of termite found in the Western Cape region of South Africa. It is endemic to the region's fynbos ecosystem. They build distinctive black termite mounds that range in height from a few centimeters to 50 centimeters. The species is commonly found on sandy soil eroded from white Table Mountain sandstone at altitudes from just under 100 meters up to 900 meters above sea level.
Reticulitermes virginicus is a species of subterranean termite native to North America, found often in the southern United States. It was described in 1907.
Reticulitermes tibialis, the arid-land subterranean termite, is a species of termite in the family Rhinotermitidae. It is found in the United States, mostly in the western half, occurring in deserts, prairies and other dry locations.
Odontotermes obesus is a species of termite in the family Termitidae. It is native to tropical southwestern Asia. This termite cultivates a symbiotic fungus in a special chamber in the nest. Workers gather vegetable detritus which they bring back to the colony, chewing up the material to make a suitable substrate on which the fungus will grow.
Heterotermes aureus, commonly known as the desert subterranean termite, is a species of termite in the family Rhinotermitidae. It is native to the deserts of North America where the colony has an underground nest.
Constrictotermes is a genus of Neotropical higher termites within the subfamily Nasutitermitinae. They form large open-air foraging columns from which they travel to and from their sources of food, similar to the Indomalayan species of processionary termites. Species of this genus commonly build epigeal or arboreal nests and feed on a variety of lichens, rotted woods and mosses.
Constrictotermes cyphergaster is a Neotropical species of open-air foraging nasute termite within the genus Constrictotermes. This species is distributed widely throughout South America and lives within xeric habitats such as the savannas found in Paraguay, Bolivia, Central Brazil, and Northern Argentina. C. cyphergaster primarily builds arboreal and transient epigeic nests and mainly consumes dead woods at varying stages of decomposition.
Rhynchotermes is a genus of Neotropical higher termites within the subfamily Syntermitinae, represented by 8 known species. Species of this genus are known for their soldiers which have highly developed, curved mandibles and a pronounced frontal tube superficially analogous to the fontanellar guns of true nasute termites. Most species forage above the surface in the open where they primarily feed on forest leaf litter. Nests are subterranean or are shallow and epigeic.
