Flanged Bombardier Beetle
Ant nest beetles (subfamily Paussinae) or paussines, some members of which are known also as flanged bombardier beetles, are a large subfamily within the ground beetles (Carabidae).The tribes Metriini, Ozaenini, Paussini and Protopaussini are included in the subfamily. Rarely seen in the open, except at lights, most Paussinae are obligate or facultative myrmecophiles, living within the nests of ants, predatory on ant larvae and worker ant, workers. Many have elaborate antennal structures and body parts flattened. Paussines are moderate sized (6–20 mm), characterised by glandular hairs that produce secretions attractive to ants and by the odd Antenna (biology), antennal structures of many species. Their pygidial glands can produce explosive secretions, with a spray of quinones that are directed forward by flanges at the posterior end of the elytra, giving them the other name of flanged bombardier beetles although they are not particularly close relatives of the typical bomba ...

Elytra
An elytron (; ; , ) is a modified, hardened forewing of beetles (Coleoptera), though a few of the true bugs (Hemiptera) such as the family Schizopteridae are extremely similar; in true bugs, the forewings are called hemelytra (sometimes alternatively spelled as "hemielytra"), and in most species only the basal half is thickened while the apex is membranous, but when they are entirely thickened the condition is referred to as "coleopteroid". An elytron is sometimes also referred to as a shard. Description The elytra primarily serve as protective wing-cases for the hindwings underneath, which are used for flying. To fly, a beetle typically opens the elytra and then extends the hindwings, flying while still holding the elytra open, though many beetles in the families Scarabaeidae and Buprestidae can fly with the elytra closed (e.g., most Cetoniinae; ). In a number of groups, the elytra are reduced to various degrees, (e.g., the beetle families Staphylinidae and Ripiphoridae), or ...

Paussus
''Paussus'' is a genus of ground beetles in the family Carabidae. There are more than 360 described species in ''Paussus'', found in Africa, Europe, and Asia. These beetles, along with others in the subfamily Paussinae, are known as flanged bombardier beetles due to their ability to explosively discharge benzoquinones, chemical irritants, at temperatures between 55° and 100 °C. A flange on their elytra assists in directing the chemicals toward the front of their bodies. All species of this genus are obligate myrmecophiles, living symbiotically in ant nests. The beetles release chemicals the ants find rewarding, and in return receive protection for themselves and their larvae. The beetles also gain a source of food in the relationship—the ants. Female ''Paussus'' lay their eggs in ant nests. The larvae develop in the nest and are apparently fed by the ants. Adult ''Paussus'' feed at will by piercing and holding an ant with their mandibles and feeding by suction. A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Coandă Effect
The Coandă effect ( or ) is the tendency of a fluid jet to stay attached to a convex surface. ''Merriam-Webster'' describes it as "the tendency of a jet of fluid emerging from an orifice to follow an adjacent flat or curved surface and to entrain fluid from the surroundings so that a region of lower pressure develops." It is named after Romanian inventor Henri Coandă, who was the first to recognize the practical application of the phenomenon in aircraft design around 1910. It was first documented explicitly in two patents issued in 1936. Discovery An early description of this phenomenon was provided by Thomas Young in a lecture given to The Royal Society in 1800: A hundred years later, Henri Coandă identified an application of the effect during experiments with his Coandă-1910 aircraft, which mounted an unusual engine he designed. The motor-driven turbine pushed hot air rearward, and Coandă noticed that the airflow was attracted to nearby surfaces. In 1934 Coandă obt ...

Stridulation
Stridulation is the act of producing sound by rubbing together certain body parts. This behavior is mostly associated with insects, but other animals are known to do this as well, such as a number of species of fish, snakes and spiders. The mechanism is typically that of one structure with a well-defined lip, ridge, or nodules (the "scraper" or ''plectrum'') being moved across a finely-ridged surface (the "file" or ''stridulitrum''—sometimes called the ''pars stridens'') or vice versa, and vibrating as it does so, like the dragging of a phonograph needle across a vinyl record. Sometimes it is the structure bearing the file which resonates to produce the sound, but in other cases it is the structure bearing the scraper, with both variants possible in related groups. Common onomatopoeic words for the sounds produced by stridulation include ''chirp'' and ''chirrup''. Arthropod stridulation Insects and other arthropods stridulate by rubbing together two parts of the body. These a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lycaenidae
Lycaenidae is the second-largest family of butterflies (behind Nymphalidae, brush-footed butterflies), with over 6,000 species worldwide, whose members are also called gossamer-winged butterflies. They constitute about 30% of the known butterfly species. The family comprises seven subfamilies, including the blues (Polyommatinae), the coppers (Lycaeninae), the hairstreaks (Theclinae), and the harvesters (Miletinae). Description, food, and life cycle Adults are small, under 5 cm usually, and brightly coloured, sometimes with a metallic gloss. Larvae are often flattened rather than cylindrical, with glands that may produce secretions that attract and subdue ants. Their cuticles tend to be thickened. Some larvae are capable of producing vibrations and low sounds that are transmitted through the substrates they inhabit. They use these sounds to communicate with ants.Pierce, N. E.; Braby, M.
