Mole Cricket
Mole crickets are members of the insect family Gryllotalpidae, in the order Orthoptera (grasshoppers, locusts, and crickets). Mole crickets are cylindrical-bodied, fossorial insects about long as adults, with small eyes and shovel-like fore limbs highly developed for burrowing. They are present in many parts of the world and where they have arrived in new regions, may become agricultural pests. Mole crickets have three life stages: eggs, nymphs, and adults. Most of their lives in these stages are spent underground, but adults have wings and disperse in the breeding season. They vary in their diet: some species are herbivores, mainly feeding on roots; others are omnivores, including worms and grubs in their diet; and a few are largely predatory. Male mole crickets have an exceptionally loud song; they sing from a burrow that opens out into the air in the shape of an exponential horn. The song is an almost pure tone, modulated into chirps. It is used to attract females, eithe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scapteriscus Borellii
''Scapteriscus borellii'', the southern mole cricket, is a species of insect in the family Gryllotalpidae. It is native to South America but is also present in the southern United States where it was introduced around 1900. Description ''Scapteriscus borellii'' is a fairly large mole cricket growing to a length of about . Like other members of this genus, it is characterized by having two sharp claws and a blade-like process with a sharp edge on its forelegs. Other mole crickets have three or four claws.Rodríguez, F.; Heads, S. (2012)New mole crickets of the genus ''Scapteriscus'' Scudder from Colombia (Orthoptera: Gryllotalpidae; Scapteriscinae).''Zootaxa'' 3282, 61–68. The two claws are separated at the base by a gap half the width of the claw, which distinguishes this species from the tawny mole cricket (''S. vicinus'') which has claws that nearly touch at the base. The tegmina (forewings) are longer than the prothorax and the membranous hind wings are longer than the a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scapteriscus Abbreviatus
''Scapteriscus abbreviatus'', the short-winged mole cricket, is a species of insect in the mole cricket family, Gryllotalpidae. It is native to South America but has been introduced inadvertently into Florida, in the United States. Unlike other related species, it is unable to fly, nor do the males emit songs in order to attract females. Description ''Scapteriscus abbreviatus'' is a medium-sized mole cricket with a length of from . Its leathery forewings are shorter than its prothorax and its membranous hind wings are shorter than its forewings, rendering it unable to fly. Members of this genus are characterized by having two sharp claws and a blade-like process with a sharp edge on their forelegs. Other mole crickets have three or four claws.Rodríguez, F.; Heads, S. (2012)New mole crickets of the genus ''Scapteriscus'' Scudder from Colombia (Orthoptera: Gryllotalpidae; Scapteriscinae).''Zootaxa'' 3282, 61–68.

Scapteriscus Vicinus
''Neoscapteriscus vicinus'', the tawny mole cricket, is a species of insect in the mole cricket family, Gryllotalpidae. This species is native to South America and also occurs in the Southern United States, where it arrived as a contaminant of ship's ballast around 1900. Colombian insect taxonomist Oscar Cadena-Castañeda studied specimens of the genus which had been called ''Scapteriscus'', and decided that it included two groups; a smaller group (the true ''Scapteriscus'') and a larger group that he named ''Neoscapteriscus'' (a new genus) in 2015. North American mole cricket taxonomists agreed with his decision and altered Orthoptera Species File Online accordingly. Description ''N. vicinus'' is a medium-sized mole cricket. Members of this genus are characterized by having two sharp claws and a blade-like process with a sharp edge on their fore legs. Other mole crickets have three or four claws. Its colour is yellowish-brown with a dark prothorax. It can be differentiated from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Larra Bicolor
''Larra bicolor'' is a parasitoid wasp native to South America. It was introduced into Florida as a biological pest control of invasive mole crickets. Description Adult females of this species are about 22 mm long, with the males somewhat smaller. The head and thorax are black, with silver markings on the head; the abdomen is red. The wings are variable in color, of a dusky hue. Life cycle These wasps feed on nectar as adults, with the shrubby false buttonweed (''Spermacoce verticillata'') preferred. Females hunt mole crickets in the genus ''Scapteriscus'', stinging them on the underside to paralyze them for several minutes. A single egg is deposited between the first and second pairs of legs. The wasp then flies off, and the cricket returns to its burrow. Nymphs and adult crickets are attacked, as long as they are large enough. Upon hatching, the larva feeds upon its host, eventually killing it. It pupates within 12 to 30 days (depending on temperature), forming a cocoo ...

Steinernema Scapterisci
''Steinernema scapterisci'', the mole cricket nematode, is a species of nematode in the order Rhabditida. It is a parasite of insects in the order Orthoptera, the grasshoppers, crickets and their allies. Native to southern South America, it was introduced into Florida in the United States in an effort to provide a biological control of pest (''Neoscapteriscus'') mole crickets. A second species of "mole cricket nematode" exists in Florida, and probably elsewhere in the eastern USA. It is now called ''Steinernema neocurtillae'' Nguyen, Smart, and is known to attack only the native mole cricket ''Neocurtilla hexadactyla'' Description ''Steinernema scapterisci'' can be distinguished from other species of its genus "by the presence of prominent cheilorhabdions, an elliptically shaped structure associated with the excretory duct, and a double-flapped epitygma in the first-generation female." It does not hybridise with '' Steinernema carpocapsae'', and it infects and kills fewer than 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ormia Depleta
''Ormia depleta'', sometimes called the Brazilian red-eyed fly, is a species of fly in the family Tachinidae. It is a parasitoid of mole crickets in the genus ''Scapteriscus''. It is native to South America but has been imported into the United States and elsewhere as a biological pest control agent. Biology ''Ormia depleta'' has four stages in its life cycle, egg, larva, pupa and adult. The adult female is attracted by the song of either the tawny mole cricket (''Neoscapteriscus vicinus'') or the southern mole cricket (''Neoscapteriscus borellii''). The repeated chirps are emitted by the male crickets to attract females to breed, and the song also lures the female fly. Her eggs hatch inside her abdomen and she deposits a larva on any mole cricket with which she comes in contact. The fly larva feeds on the mole cricket and eventually kills it, then the fly larva emerges from the carcass and makes its way into the soil where it pupates. The adult fly emerges from the pupa about ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ensifera
Ensifera is a suborder of insects that includes the various types of crickets and their allies including: true crickets, camel crickets, bush crickets or katydids, grigs, weta and Cooloola monsters. This and the suborder Caelifera (grasshoppers and their allies) make up the order Orthoptera. Ensifera is believed to be a more ancient group than Caelifera, with its origins in the Carboniferous period, the split having occurred at the end of the Permian period. Unlike the Caelifera, the Ensifera contain numerous members that are partially carnivorous, feeding on other insects, as well as plants. ''Ensifer'' is Latin for "sword bearer", and refers to the typically elongated and blade-like ovipositor of the females. Characteristics Characteristics shared by the two orthopteran suborders, Caelifera and Ensifera, are the mouthparts adapted for biting and chewing, the modified prothorax, the hind legs modified for jumping, the wing shape and venation, and the sound-producing stridu ...

Leatherback Sea Turtle
The leatherback sea turtle (''Dermochelys coriacea''), sometimes called the lute turtle or leathery turtle or simply the luth, is the largest of all living turtles and the heaviest non-crocodilian reptile, reaching lengths of up to and weights of . It is the only living species in the genus ''Dermochelys'' and family Dermochelyidae. It can easily be differentiated from other modern sea turtles by its lack of a bony shell; instead, its carapace is covered by oily flesh and flexible, leather-like skin, for which it is named. Taxonomy and evolution Taxonomy ''Dermochelys coriacea'' is the only species in genus ''Dermochelys''. The genus, in turn, contains the only extant member of the family Dermochelyidae. Domenico Agostino Vandelli named the species first in 1761 as ''Testudo coriacea'' after an animal captured at Ostia and donated to the University of Padua by Pope Clement XIII. In 1816, French zoologist Henri Blainville coined the term ''Dermochelys''. The leatherback was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthropod
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a Segmentation (biology), segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and Arthropod cuticle, cuticle made of chitin, often Mineralization (biology), 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 exoskeleton, 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 Organ (anatomy), organs; it has an open circulatory system. Like their exteriors, the internal or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crabronidae
The Crabronidae are a large paraphyletic group (nominally a family) of wasps, including nearly all of the species formerly comprising the now-defunct superfamily Sphecoidea. It collectively includes well over 200 genera, containing well over 9000 species. Crabronids were originally a part of Sphecidae, but the latter name is now restricted to a separate family based on what was once the subfamily Sphecinae. Several of the subfamilies of Crabronidae are often treated as families in their own right, as is true of the most recent phylogenies (example below). Phylogeny This phylogenetic tree is based on Sann ''et al.'', 2018, which used phylogenomics to demonstrate that both the bees (Anthophila) and the Sphecidae arose from within the former Crabronidae, which is therefore paraphyletic, and which they suggested should be split into several families; the former family Heterogynaidae nests within the Bembicidae, as here defined. These findings differ in several details from studie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
