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.

Taxonomy

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]

Description

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]

Distribution and habitat

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]

Ecology

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.

<span class="mw-page-title-main">Green-head ant</span> Species of ant

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.

<span class="mw-page-title-main">Hodotermitidae</span> Family of termites

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.
