Pantala hymenaea | |
Pantala hymenaea (spot-winged glider) [1] is a dragonfly of the family Libellulidae. It is a migratory species and is native to North, Central and South America, travelling widely and breeding in temporary water bodies. It looks very similar to the wandering glider, with the addition of a dark basal spot on the hindwing. It is a common species with a very large range and the International Union for Conservation of Nature has listed it as being of "least concern".
P. hymenaea, otherwise known as the spot-winged glider, is a robust species with a cylindrical abdomen and broad hindwings. Its length is about 5 cm (2 in) and its wingspan 7.5 cm (3 in). The eyes are red and the face is also red in breeding males. The general body color is brown, and females and immatures have a diagonal white marking on the thorax. [3] There is a small dark brown spot at the base of the hindwings which distinguishes this species from the otherwise similar wandering glider (Pantala flavescens). [4]
The spot-winged glider is a widespread and common species in the New World, occurring in North, Central and South America. Its range includes six provinces in Canada (British Columbia, Manitoba, New Brunswick, Nova Scotia, Ontario and Québec), 45 states in the United States, 24 states in Mexico, the West Indies, and Central and much of South America, extending as far south as Argentina. It is a migratory species and a strong flier.
The species likely breeds in all occupied territory, with the exception of British Columbia and Manitoba, where it is probably a vagrant. Breeding takes place in temporary wetlands, flooded areas, pools and garden ponds. The most important factor for successful breeding is likely the absence of fish, as the nymphs feed in the open. [1]
The spot-winged glider is a known predator of Anopheles freeborni , the western malaria mosquito. It primarily feeds on A. freeborni at dusk, during which the mosquitoes commonly swarm. As it gets darker, predation decreases due to the importance of visual stimuli in the ability of P. hymenaea to detect its prey. [5]
In North America, there is a northward migration of these dragonflies from tropical areas in the summer, and a southerly migration in the fall; presumably these are a different generation, but the biology of this species is little known. [3]
The common swift is a medium-sized bird, superficially similar to the barn swallow or house martin but somewhat larger, though not stemming from those passerine species, being in the order Apodiformes. The resemblances between the groups are due to convergent evolution, reflecting similar contextual development. The swifts' nearest relatives are the New World hummingbirds and the Southeast Asian treeswifts.
The red-winged blackbird is a passerine bird of the family Icteridae found in most of North America and much of Central America. It breeds from Alaska and Newfoundland south to Florida, the Gulf of Mexico, Mexico, and Guatemala, with isolated populations in western El Salvador, northwestern Honduras, and northwestern Costa Rica. It may winter as far north as Pennsylvania and British Columbia, but northern populations are generally migratory, moving south to Mexico and the Southern United States. Claims have been made that it is the most abundant living land bird in North America, as bird-counting censuses of wintering red-winged blackbirds sometimes show that loose flocks can number in excess of a million birds per flock and the full number of breeding pairs across North and Central America may exceed 250 million in peak years. It also ranks among the best-studied wild bird species in the world. The red-winged blackbird is sexually dimorphic; the male is all black with a red shoulder and yellow wing bar, while the female is a nondescript dark brown. Seeds and insects make up the bulk of the red-winged blackbird's diet.
The red-breasted merganser is a duck species that is native to much of the Northern Hemisphere. The red breast that gives the species its common name is only displayed by males in breeding plumage. Individuals fly rapidly, and feed by diving from the surface to pursue aquatic animals underwater, using serrated bills to capture slippery fish. They migrate each year from breeding sites on lakes and rivers to their mostly coastal wintering areas, making them the only species in the genus Mergus to frequent saltwater. They form flocks outside of breeding season that are usually small but can reach 100 individuals. The worldwide population of this species is stable, though it is threatened in some areas by habitat loss and other factors.
The green heron is a small heron of North and Central America. Butorides is from Middle English butor "bittern" and Ancient Greek -oides, "resembling", and virescens is Latin for "greenish".
The killdeer is a large plover found in the Americas. It gets its name from its shrill, two-syllable call, which is often heard. It was described and given its current scientific name in 1758 by Carl Linnaeus in the 10th edition of his Systema Naturae. Three subspecies are described. Its upperparts are mostly brown with rufous fringes, the head has patches of white and black, and two black bands cross the breast. The belly and the rest of the breast are white. The nominate subspecies breeds from southeastern Alaska and southern Canada to Mexico. It is seen year-round in the southern half of its breeding range; the subspecies C. v. ternominatus is resident in the West Indies, and C. v. peruvianus inhabits Peru and surrounding South American countries throughout the year. North American breeders winter from their resident range south to Central America, the West Indies, and the northernmost portions of South America.
The solitary sandpiper is a small shorebird. The genus name Tringa is the Neo-Latin name given to the green sandpiper by Aldrovandus in 1599 based on Ancient Greek trungas, a thrush-sized, white-rumped, tail-bobbing wading bird mentioned by Aristotle. The specific solitaria is Latin for "solitary" from solus, "alone".
The common nighthawk or bullbat is a medium-sized crepuscular or nocturnal bird of the Americas within the nightjar (Caprimulgidae) family, whose presence and identity are best revealed by its vocalization. Typically dark, displaying cryptic colouration and intricate patterns, this bird is difficult to spot with the naked eye during the day. This bird is most conspicuous when in its buoyant and erratic flight. The most remarkable feature of this aerial insectivore is its small beak that belies the massiveness of its mouth. Some claim appearance similarities to owls. With its horizontal stance and short legs, the common nighthawk does not travel frequently on the ground, instead preferring to perch horizontally, parallel to branches, on posts, on the ground or on a roof. The males of this species may roost together but the bird is primarily solitary. The common nighthawk shows variability in territory size.
Forster's tern is a tern in the family Laridae. The genus name Sterna is derived from Old English "stearn", "tern", and forsteri commemorates the naturalist Johann Reinhold Forster.
The veery is a small North American thrush species, a member of a group of closely related and similar species in the genus Catharus, also including the gray-cheeked thrush, Bicknell's thrush, Swainson's thrush, and hermit thrush. Alternate names for this species include Wilson's thrush and tawny thrush. Up to six subspecies exist, which are grouped into the eastern veery, the western veery or willow thrush, and the Newfoundland veery.
The blackpoll warbler is a New World warbler. Breeding males are mostly black and white. They have a prominent black cap, white cheeks, and white wing bars. The blackpoll breeds in forests of northern North America, from Alaska throughout most of Canada, to the Adirondack Mountains of New York as well as New England in the Northeastern United States. They are a common migrant throughout much of North America. In fall, they fly south to the Greater Antilles and the northeastern coasts of South America in a non-stop long-distance migration over open water, averaging 2,500 km (1,600 mi), one of the longest-distance non-stop overwater flights ever recorded for a migratory songbird. Rare vagrants to western Europe, they are one of the more frequent transatlantic passerine wanderers.
The American oystercatcher, occasionally called the American pied oystercatcher, is a member of family Haematopodidae. Originally called the "sea pie", it was renamed in 1731 when naturalist Mark Catesby claimed that he had observed the bird eating oysters. The current population of American oystercatchers is estimated to be 43,000. There are estimated to be 1,500 breeding pairs along the Atlantic and Gulf Coasts of the US. The bird is marked by its black and white body and a long, thick orange beak.
The green darner or common green darner, after its resemblance to a darning needle, is a species of dragonfly in the family Aeshnidae. One of the most common and abundant species throughout North America, it also ranges south to Panama. It is well known for its great migration distance from the northern United States south into Texas and Mexico. It also occurs in the Caribbean, Tahiti, and Asia from Japan to mainland China. It is the official insect for the state of Washington in the United States.
Pantala flavescens, the globe skimmer, globe wanderer or wandering glider, is a wide-ranging dragonfly of the family Libellulidae. This species and Pantala hymenaea, the "spot-winged glider", are the only members of the genus Pantala. It was first described by Johan Christian Fabricius in 1798. It is considered to be the most widespread dragonfly on the planet, with good population on every continent except Antarctica, although rare in Europe. Globe skimmers make an annual multigenerational journey of some 18,000 km ; to complete the migration, individual globe skimmers fly more than 6,000 km —one of the farthest known migrations of all insect species.
Erythemis collocata, the western pondhawk, is a dragonfly of the family Libellulidae, native to western Canada, the western United States, and Mexico.
The Amur falcon is a small raptor of the falcon family. It breeds in south-eastern Siberia and Northern China before migrating in large flocks across India and over the Arabian Sea to winter in Southern and East African coasts.
Insect migration is the seasonal movement of insects, particularly those by species of dragonflies, beetles, butterflies and moths. The distance can vary with species and in most cases, these movements involve large numbers of individuals. In some cases, the individuals that migrate in one direction may not return and the next generation may instead migrate in the opposite direction. This is a significant difference from bird migration.
Tramea basilaris, also known as the keyhole glider, red marsh trotter, or wheeling glider, is a species of dragonfly in the family Libellulidae. It is found throughout most of Africa, Arabia and in Asia. Capable of very long migration and nomadic flight, it reached Europe once, being recorded at the island of Linosa, Sicily (Italy) in 2016. Similarly, this species is able to use the trade winds to reach the Caribbean and South Americas, where it was caught in Suriname, "Guadeloupe" and "martinique".
Aeshna canadensis, the Canada darner, is a species of dragonfly in the family Aeshnidae. It is common throughout southern Canada and the northern United States.
Swainson's hawk is a large bird species in the Accipitriformes order. This species was named after William Swainson, a British naturalist. It is colloquially known as the grasshopper hawk or locust hawk, as it is very fond of Acrididae and will voraciously eat these insects whenever they are available.
Anopheles freeborni, commonly known as the western malaria mosquito, is a species of mosquito in the family Culicidae. It is typically found in the western United States and Canada. Adults are brown to black, with yellow-brown hairs and gray-brown stripes on the thorax. Their scaly wings have four dark spots, which are less distinct in the male.
