Microstigma Rotundatum
''Microstigma rotundatum'', the helicopter damselfly, is a species of damselflies belonging to the family Pseudostigmatidae. Description ''Microstigma rotundatum'' is the most common species within the family. These damselflies have a long, thin body and large wings with a dense venation. The apex of the forewings has large yellow flecks and the pseudostigma shows many cells.Charles W. HeckmaEncyclopedia of South American Aquatic Insects: Odonata - Zygoptera/ref> Biology These damselflies mainly prey on web-building spiders. Larvae develop in water-filled crevices of fallen trees and in phytotelmata, the bodies of water held by some plants ( bromeliads).Diomedes Quintero, Annette Aiello Annette A.

Damselflies
Damselflies are flying insects of the suborder Zygoptera in the order Odonata. They are similar to dragonflies, which constitute the other odonatan suborder, Anisoptera, but are smaller and have slimmer bodies. Most species fold the wings along the body when at rest, unlike dragonflies which hold the wings flat and away from the body. An ancient group, damselflies have existed since at least the Lower Permian, and are found on every continent except Antarctica. All damselflies are predatory insects; both nymphs and adults actively hunt and eat other insects. The nymphs are aquatic, with different species living in a variety of freshwater habitats including acidic bogs, ponds, lakes and rivers. The nymphs moult repeatedly, at the last moult climbing out of the water to undergo metamorphosis. The skin splits down the back, they emerge and inflate their wings and abdomen to gain their adult form. Their presence on a body of water indicates that it is relatively unpolluted, but t ...

Arthropods Of Colombia
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and cuticle made of chitin, often mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior organs; it has an open circulatory system. Like their exteriors, the internal organs of arthropods are generally built of repeated segments. Their nervous system is "ladder-li ...

Odonata Of South America
Odonata is an order of flying insects that includes the dragonflies and damselflies. Members of the group first appeared during the Triassic, though members of their total group, Odonatoptera, first appeared in Late Carboniferous. The two common groups are distinguished with dragonflies, placed in the suborder Epiprocta, usually being larger, with eyes together and wings up or out at rest, while damselflies, suborder Zygoptera, are usually smaller with eyes placed apart and wings along body at rest. All Odonata have aquatic larvae called naiads (nymphs), and all of them, larvae and adults, are carnivorous. The adults can land, but rarely walk. Their legs are specialised for catching prey. They are almost entirely insectivorous. Etymology and terminology Fabricius coined the term ''Odonata'' in 1793 from the Ancient Greek ( Ionic form of ) 'tooth'. One hypothesis is that it was because their maxillae are notably toothed. Most insects also have toothed mandibles. The word ' ...

Bromeliads
The Bromeliaceae (the bromeliads) are a family of monocot flowering plants of about 80 genera and 3700 known species, native mainly to the tropical Americas, with several species found in the American subtropics and one in tropical west Africa, '' Pitcairnia feliciana''. It is among the basal families within the Poales and is the only family within the order that has septal nectaries and inferior ovaries.Judd, Walter S. Plant systematics a phylogenetic approach. 3rd ed. Sunderland, MA: Sinauer Associates, Inc., 2007. These inferior ovaries characterize the Bromelioideae, a subfamily of the Bromeliaceae. The family includes both epiphytes, such as Spanish moss ('' Tillandsia usneoides''), and terrestrial species, such as the pineapple ('' Ananas comosus''). Many bromeliads are able to store water in a structure formed by their tightly overlapping leaf bases. However, the family is diverse enough to include the tank bromeliads, grey-leaved epiphyte ''Tillandsia'' species tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phytotelmata
Phytotelma (plural phytotelmata) is a small water-filled cavity in a terrestrial plant. The water accumulated within these plants may serve as the habitat for associated fauna and flora. A rich literature in German summarised by Thienemann (1954) developed many aspects of phytotelm biology. Reviews of the subject by Kitching (1971) and Maguire (1971) introduced the concept of phytotelmata to English-speaking readers. A multi-authored book edited by Frank and Lounibos (1983)Frank, J.H. and Lounibos, L.P. (1983) ''Phytotelmata: Terrestrial plants as hosts for aquatic insect communities'', Plexus Press. dealt in 11 chapters with classification of phytotelmata, and with phytotelmata provided by bamboo internodes, banana leaf axils, bromeliad leaf axils, ''Nepenthes'' pitchers, ''Sarracenia'' pitchers, tree holes, and ''Heliconia'' flower bracts and leaf rolls. A classification of phytotelmata by Kitching (2000) recognizes five principal types: bromeliad tanks, certain carnivo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spider
Spiders (order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel, however, as there is currently neither paleontological nor embryological evidence that spiders ever had a sep ...

Edmond De Sélys Longchamps
Baron Michel Edmond de Selys Longchamps (25 May 1813 – 11 December 1900) was a Belgian Liberal Party politician and scientist. Selys Longchamps has been regarded as the founding figure of odonatology, the study of the dragonflies and damselflies. His wealth and influence enabled him to amass one of the finest collections of neuropteroid insects and to describe many species from around the world. His collection is housed in the Royal Belgian Institute of Natural Sciences. Biography Selys was a wealthy aristocrat born in Paris to Michel Laurent de Selys Longchamps and Marie-Denise Gandolphe. He was educated at home by private tutors and never attended school or university. Nevertheless, he became known as the world's leading authority on Odonata as well as an expert on Neuroptera and European Orthoptera. He was also a leading ornithologist. A Liberal Party representative in the Belgian Parliament, he became Councillor for Waremme in 1846, entered the Belgian Senate in ...

Pseudostigmatidae
The Pseudostigmatidae are a family of tropical damselflies, known as helicopter damselflies, giant damselflies, or forest giants. The family includes the largest of all damselfly species. They specialize in preying on web-building spiders, and breed in phytotelmata, the small bodies of water held by plants such as bromeliads. Range The species traditionally placed in Pseudostigmatidae are all Neotropical. Two range as far as northeastern Mexico: ''Mecistogaster ornata'' occurs in Tamaulipas and ''Pseudostigma aberrans'' in both Tamaulipas and Nuevo León. In 2006, molecular phylogenetic analysis confirmed that the African damselfly '' Coryphagrion grandis'', previously often classified within Megapodagrionidae or in a monotypic family Coryphagrionidae, belonged within family Pseudostigmatidae, close to genus ''Mecistogaster'', as was proposed already ten years before. This finding suggests that the family dates back to before the breakup of the supercontinent Gondwana. Mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
