Constrictotermes cavifrons (Holmgren, 1910) | |
Constrictotermes cavifrons [1] [2] is a species of Amazonian nasute termite within the genus Constrictotermes . [3] It forms large and diurnal open-foraging trails to and from its sources of food which consists largely of lichens and other microepiphytes. The nests of C. cavifrons are arboreal and characterized by a cleared central runway from which foraging raids begin. [3]
The soldiers have antennae with 13 – 14 articles (antennomeres) and the length of the head ranges between 1.25 – 1.50 mm. [4] The head and abdomen segments are pigmented dark in contrast to the conspicuously yellowish thorax, matching the coloration of workers. Soldiers of this species molt from sclerotized worker-like forms which are slightly smaller than the actual workers but otherwise appear to behave no differently. The head of the presoldier form measures between 0.839 – 0.887 mm while workers range between 0.936 – 1.036 mm. The slit-shaped fontanelle of the presoldier form is also larger and more defined. During the molt the third and fourth antenna segments fuse and all antenna segments post-molt are more elongated than in the presoldier worker-like form. [5]
The imago of this species has a brownish black, broadly oval head capsule which is sparsely covered by long hair. The fontanelle is slit-shaped and forks at the tip. The antennae consists of 15 segments with the second article equal in length to the fourth; third article is more than double the length of the 2nd article. Eyes and ocelli are large and the postclypeus is black brown with no distinct median line. The wings are a dark smokey color and the venation is conspicuous. Length with wings included is 17 – 19 mm, body length excluding wings is between 8 – 10 mm. [6]
The nests are arboreal and typically found 10 meters high on a host tree. Unlike the nests of other arboreal species which are dark in color, indicative of significant lignocellulose content, the nests of C. cavifrons have lighter coloration indicating a higher amount of mineral soil used in construction. Nests are mainly characterized by their elongate shape that tapers into a central runway which is either flanked by gallery walls on either side and/or by downward sloping narrow ridges. These narrow ridges are the most diagnostic feature of their nests, and are believed to aid in diverting rainfall from the central runway. [3]
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.
Blattodea is an order of insects that contains cockroaches and termites. Formerly, termites were considered a separate order, Isoptera, but genetic and molecular evidence suggests they evolved from within the cockroach lineage, cladistically making them cockroaches as well. The Blattodea and the mantis are now all considered part of the superorder Dictyoptera. Blattodea includes approximately 4,400 species of cockroach in almost 500 genera, and about 3,000 species of termite in around 300 genera.
Bombus fraternus is an endangered species of bumblebee known commonly as the Southern Plains bumblebee. It is native to the United States east of the Rocky Mountains. It is most often encountered in the southern Great Plains and along the Gulf Coastal Plain. This species has been found as far north as New Jersey and North Dakota, and as far south as Florida along the Gulf Coastal Plain into the state of Chihuahua in Mexico. This species was uncommon historically, but having faced declines in population; its estimated abundance is less than 15% of historical numbers.
The black carpenter ant is one of the largest and most common species of carpenter ant native to the central and eastern United States as well as eastern Canada.
The blue-capped manakin is a species of bird in the family Pipridae. The males have a brilliant blue cap; some have black, others have green body plumage, but the relationship between the subspecies is not well understood.
Ochetellus glaber is a species of ant native to Australia. A member of the genus Ochetellus in the subfamily Dolichoderinae, it was described by Austrian entomologist Gustav Mayr in 1862. Aside from Australia, O. glaber has been introduced to a number of countries, including China, India, Japan, New Zealand, the Philippines and the United States, where it has established itself in Hawaii and Florida. It has been found on Lord Howe Island, New Caledonia, Norfolk Island, Réunion, New Zealand, and the Solomon Islands. Compared with other ants, O. glaber is a small species, with workers measuring 2–3 mm (0.079–0.118 in). Males are the smallest at 1.6 mm (0.063 in), while the queens measure 5.2–5.5 mm (0.20–0.22 in). The ant's colour ranges from brown to black.
Pheidole megacephala is a species of ant in the family Formicidae. It is commonly known as the big-headed ant in the US and the coastal brown ant in Australia. It is a very successful invasive species and is considered a danger to native ants in Australia and other places. It is regarded as one of the world's worst invasive ant species.
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.
Zophotermes is an extinct genus of termite in the Isoptera family Rhinotermitidae known from two Eocene fossils found in India. The genus contains a single described species, Zophotermes ashoki placed in the subfamily Prorhinotermitinae.
Nanotermes is an extinct genus of termites in the Isoptera family Termitidae known from only one Eocene fossil found in amber of the Cambay Basin. The genus contains a single described species, Nanotermes isaacae placed tentatively in the subfamily Termitinae.
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.
Coptotermes frenchi, the Australian subterranean termite, is a species of termite in the family Rhinotermitidae. Termites are social insects and C. frenchi usually builds its communal nest in the root crown of a tree. From this, a network of galleries extends through the nearby soil, enabling the workers to forage in the surrounding area without emerging on the surface of the ground.
Coptotermes acinaciformis is a species of subterranean termite in the family Rhinotermitidae native to Australia. Termites are social insects and build a communal nest. In the case of C. acinaciformis, this is either in the root crown of a tree or underground. From this, a network of galleries extends through the nearby soil, enabling the workers to forage in the surrounding area without emerging on the surface of the ground. This termite can cause substantial damage to trees and the wooden parts of buildings.
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.
Coptotermes elisae, the Papuan plantation termite, is a species of termite in the family Rhinotermitidae. It is native to New Guinea, Indonesia, and Southeast Asia, where it attacks and kills living trees and damages structural timbers.
Hospitalitermes is an Asian–Papuan genus of lichen eating termite in the subfamily Nasutitermitinae. There are 37 species currently listed, of which most are recognized for their extensive surface foraging columns. Due to their conspicuous foraging activities they are commonly known as processionary or marching termites. They often inhabit cavities inside of living trees excavated by other species of termite.
Syntermes is a genus of large Neotropical higher termites within the subfamily Syntermitinae. The genus is found only in South America where members are distributed widely throughout the continent, being found from the tropical rainforests of Colombia to the savannas of Brazil and Northern Argentina.
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.
