Brachytrupes Megacephalus
''Brachytrupes megacephalus'' is a species of cricket in the family Gryllidae. Description and behavior ''Brachytrupes megacephalus'' can reach a length of about . This species is characterized by a very large head (hence the species name ''megacephalus'') and strong jaws. The tibia of the front and rear legs are armed with big teeth which facilitate the action of digging the deep holes in sandy soils in which these crickets live. These insects have crepuscular and nocturnal habits. The mating period extends from mid-March to the end of April. After mating, the males keep the females captive in their holes until they lay their eggs. Distribution and habitat This species can be found in sandy environments in Sardinia, Sicily, Malta and North Africa North Africa, or Northern Africa is a region encompassing the northern portion of the African continent. There is no singularly accepted scope for the region, and it is sometimes defined as stretching from the Atlantic shores of ...

Animals are multicellular, eukaryotic organisms in the Kingdom (biology), biological kingdom Animalia. With few exceptions, animals Heterotroph, consume organic material, Cellular respiration#Aerobic respiration, breathe oxygen, are Motility, able to move, can Sexual reproduction, reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of Cell (biology), cells, the blastula, during Embryogenesis, embryonic development. Over 1.5 million Extant taxon, living animal species have been Species description, described—of which around 1 million are Insecta, insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have Ecology, complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a Symmetry in biology#Bilate ...

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 ...

Insect
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. ...

Orthoptera
Orthoptera () is an order of insects that comprises the grasshoppers, locusts, and crickets, including closely related insects, such as the bush crickets or katydids and wētā. The order is subdivided into two suborders: Caelifera – grasshoppers, locusts, and close relatives; and Ensifera – crickets and close relatives. More than 20,000 species are distributed worldwide. The insects in the order have incomplete metamorphosis, and produce sound (known as a "stridulation") by rubbing their wings against each other or their legs, the wings or legs containing rows of corrugated bumps. The tympanum, or ear, is located in the front tibia in crickets, mole crickets, and bush crickets or katydids, and on the first abdominal segment in the grasshoppers and locusts. These organisms use vibrations to locate other individuals. Grasshoppers and other orthopterans are able to fold their wings (i.e. they are members of Neoptera). Etymology The name is derived from the Greek ὀρθό ...

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 ...

Grylloidea
Grylloidea is the superfamily of insects, in the order Orthoptera, known as crickets. It includes the " true crickets", scaly crickets, wood crickets and other families, some only known from fossils. Grylloidea dates from the Triassic period and contains about 3,700 known living species in some 528 genera, as well as 43 extinct species and 27 extinct genera. Characteristics The features which distinguish crickets in the superfamily Grylloidea from other Ensiferans are long, thread-like antennae, three tarsal segments, slender tactile cerci at the tip of the abdomen and bulbous sensory bristles on the cerci. They are the only insects to share this combination of characteristics. The term cricket is popularly used for any cricket-like insect in the order Ensifera, being applied to the ant crickets, bush crickets (Tettigoniidae), Jerusalem crickets (''Stenopelmatus''), mole crickets, camel crickets and cave crickets (Rhaphidophoridae) and wētā (Anostostomatidae), and the re ...

Gryllidae
The family ''Gryllidae'' contains the subfamilies and genera which entomologists now term true crickets. Having long, whip-like antennae, they belong to the Orthopteran suborder Ensifera, which has been greatly reduced in the last 100 years (''e.g.'' ImmsImms AD, rev. Richards OW & Davies RG (1970) ''A General Textbook of Entomology'' 9th Ed. Methuen 886 pp.): taxa such as the spider-crickets and allies, sword-tail crickets, wood or ground crickets and scaly crickets have been elevated to family level. The type genus is ''Gryllus'' and the first use of the family name "Gryllidae" was by Walker. They have a worldwide distribution (except Antarctica). The largest members of the family are the -long bull crickets (''Brachytrupes'') which excavate burrows a metre or more deep. The tree crickets (Oecanthinae) are delicate white or pale green insects with transparent fore wings, while the field crickets (Gryllinae) are robust brown or black insects. Subfamilies The family is ...

Gryllinae
Gryllinae, or field crickets, are a subfamily of insects in the order Orthoptera and the family Gryllidae. They hatch in spring, and the young crickets (called nymphs) eat and grow rapidly. They shed their skin (molt) eight or more times before they become adults. Field crickets eat a broad range of food: seeds, plants, or insects (dead or alive). They are known to feed on grasshopper eggs, pupae of Lepidoptera (moths and butterflies) and Diptera (flies). Occasionally they may rob spiders of their prey. Field crickets also eat grass. In the British Isles "field cricket" refers specifically to ''Gryllus campestris'', but the common name may also be used for '' G. assimilis'', '' G. bimaculatus'', '' G. firmus'', '' G. pennsylvanicus'', '' G. rubens'', and '' G. texensis'', along with other members of various genera including ''Acheta'', '' Gryllodes'', ''Gryllus'', and ''Teleogryllus''. ''Acheta domesticus'', the House cricket, and ''Gryllus bimaculatus'' are raised in captivity ...

Cricket (insect)
Crickets are orthopteran insects which are related to bush crickets, and, more distantly, to grasshoppers. In older literature, such as Imms,Imms AD, rev. Richards OW & Davies RG (1970) ''A General Textbook of Entomology'' 9th Ed. Methuen 886 pp. "crickets" were placed at the family level (''i.e.'' Gryllidae), but contemporary authorities including Otte now place them in the superfamily Grylloidea. The word has been used in combination to describe more distantly related taxa in the suborder Ensifera, such as king crickets and mole crickets. Crickets have mainly cylindrically-shaped bodies, round heads, and long antennae. Behind the head is a smooth, robust pronotum. The abdomen ends in a pair of long cerci; females have a long, cylindrical ovipositor. Diagnostic features include legs with 3-segmented tarsi; as with many Orthoptera, the hind legs have enlarged femora, providing power for jumping. The front wings are adapted as tough, leathery elytra, and some crickets ...
