Cordulegastridae - это семейство одонаты ( дракозоны ) из подкоренного порядка Anisoptera . Они обычно известны как шипы . [ 2 ] Некоторые народные названия для видов этого семейства - Biddie и Flying Adder . [ 3 ] У них большие, коричневые или черные тела с желтой маркировкой и узкие неопухолевые крылья. Их яркие глаза касаются одной точки, и их можно найти вдоль небольших, чистых лесных ручьев, медленно летящих на 30-70 см над водой. Однако, когда они нарушены, они могут летать очень быстро. Они обычно охотятся высоко в лесной растительности и предпочитают запечатлеть добычу, отдыхая на листьях или ветвях (известные как защелки). [ 4 ]
Таксономия
[ редактировать ]В семействе CorduleGastridae есть 51 вид среди трех различных родов. Эти роды включают Anotogaster , Cordulegaster и Neallogaster , которые имеют 15, 30 и 6 видов соответственно [ 5 ]
Название Cordulegastridae происходит от греческого kordylinus , «клуба» и гастрая , живот. женщинам Общее название Spiketails относится к выдающимся яйцам . [ 2 ]
Description
[edit]Dragonflies within this family are typically large, between 2.5 to 3 inches long. They are characteristically black in color and have blue-green eyes. On their large black bodies they have paired yellow spots along the length of their abdomen. Females and males are generally similar but two key differences are the color of the forehead and the terminal segment of their abdomen. Males have yellow foreheads and slightly clubbed abdomen whereas females have brown foreheads and an ovipositor extending from the end of the abdomen.[6]
Natural history
[edit]Life cycle and behavior
[edit]A typical lifespan of Cordulegastridae dragonflies is 3–5 years.[7] Adults are usually active and flying between spring and early summer with a peak in June.[8]
The Cordulegastridae usually lay their eggs in the sand in shallow water, the female hovering just above the water with her body in a vertical position, and making repeated dips into the water with her abdomen.[9] The females trap air bubbles with hairs along their bodies to allow them to reach the bottom of the water and deposit eggs into the substrate.[10] Males are remarkably territorial and their territorial behavior varies based on the oviposition of the females.[8]
Cordulegastridae nymphs will almost entirely conceal themselves in sand or silt, exposing only their eyes to see, antennae for sensing prey, and the tip of their abdomen to breathe dissolved oxygen.[11] Nymphs will consume any prey they can capture, going as far as eating smaller larvae of the same species.[12] This family captures their prey by extending their labium, categorizing them as ambush predators.[7]
Habitat
[edit]Since nymphs are aquatic and adults are terrestrial, their habitats are quite different. The preferred habitat of Cordulegastridae nymphs are small lotic or flowing streams with clean sand and silt substrates.[10][7] Adults on the other hand fly above clear streams and small rivers in the woods, with females only entering the water to lay their eggs.[6]
Distribution
[edit]
Their distribution includes North America, South America, Europe, Asia and Africa.[13] All eight species in North America belong to the genus Cordulegaster.[3]
Conservation
[edit]
Although the conservation status of many if not most species of this family is unknown, there are multiple species that are of concern. From the Conservation Status Assessment of Odonata for the Northeastern United States, Cordulegaster erronea and Cordulegaster bilineata were identified as highly vulnerable, and Cordulegaster obliqua was identified as moderately vulnerable.[14] There are five species of concern according to the International Union for Conservation of Nature and Natural Resources (IUCN), Cordulegaster bidentata, Cordulegaster heros, Cordulegaster trinacriae, Cordulegaster helladica and Cordulegaster sarracenia. C. bidentata, C. trinacriae and C. heros are identified as Near Threatened and found in Europe. Most threatened however are C. helladica and C. sarracenia which are Endangered on the IUCN Red List due to significant habitat loss.[15][failed verification]
