Wing Case
An elytron (; ; : elytra, ) 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 Ripiphori ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maybug
The common cockchafer (''Melolontha melolontha''), also colloquially known as the Maybug, Maybeetle, or doodlebug, is a species of scarab beetle belonging to the genus ''Melolontha.'' It is native to Europe, and it is one of several closely-related and morphologically similar species of ''Melolontha'' called cockchafers, alongside ''Melolontha hippocastani'' (the forest cockchafer)''.'' The cockchafer develops via metamorphosis, in which the beetle undergoes stages of eggs, larvae, pupae and adults. The mating behaviour is controlled by pheromones. The males usually swarm during the mating season while the females stay put and feed on leaves. The leaves release green leaf volatiles when they are fed on by females, which the male can sense and thus locate the female for mating opportunity. The larvae use both the plant volatiles and CO2 to locate the plant root for food. This species is an important and nutritious food source for many species. The adults and larvae feed on plant ...

Staphylinidae
The rove beetles are a family (biology), family (Staphylinidae) of beetles, primarily distinguished by their short elytra (wing covers) that typically leave more than half of their abdominal segments exposed. With over 66,000 species in thousands of genera, the group is one of the largest families in the beetle order, and one of the largest families of organisms. It is an ancient group that first appeared during the Middle Jurassic based on definitive records of fossilized rove beetles, with the Late Triassic taxon ''Leehermania'' more likely belonging to Myxophaga. They are an ecologically and morphologically diverse group of beetles, and commonly encountered in terrestrial ecosystems. One well-known species is the devil's coach-horse beetle (''Ocypus olens''). For some other species, see List of rove beetle (Staphylinidae) species recorded in Britain, list of British rove beetles. Anatomy As might be expected for such a large family, considerable variation exists among the spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unpowered Flight
Unpowered flight is the ability to stay airborne for a period of time without using any power source. There are several types of unpowered flight. Some have been exploited by nature, others by humankind, and some by both. Unpowered aircraft are aerial vehicles that can fly without any propulsion mechanism. The ability to fly short or long distances without power has evolved many times in nature. Many creatures capable of sustained wing-powered flight also soar unpowered for much of the time they are airborne. Flight without power Classification of flight methods Pennycuick divides animal flight into three types: parachuting, gliding and powered. He observes however that these have no sharp boundaries. For example, at one point he sees parachutes as unpowered and as a primitive form of soaring, while soaring itself he sees as being powered by air movement (wind). Other methods, such as lighter-than-air flight, are used only by man. This article makes the following distinctions b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minecraft
''Minecraft'' is a 2011 sandbox game developed and published by the Swedish video game developer Mojang Studios. Originally created by Markus Persson, Markus "Notch" Persson using the Java (programming language), Java programming language, the first public alpha build was released on 17 May 2009.

Weevil
Weevils are beetles belonging to the superfamily Curculionoidea, known for their elongated snouts. They are usually small – less than in length – and herbivorous. Approximately 97,000 species of weevils are known. They belong to several families, with most of them in the family Curculionidae (the true weevils). It also includes bark beetles, which while morphologically dissimilar to other weevils in lacking the distinctive snout, is a subfamily of Curculionidae. Some other beetles, although not closely related, bear the name "weevil", such as the leaf beetle subfamily Bruchinae, known as "bean weevils", or the biscuit weevil (''Stegobium paniceum''), which belongs to the family Ptinidae. Many weevils are considered pests because of their ability to damage and kill crops. The grain or wheat weevil (''Sitophilus granarius'') damages stored grain, as does the maize weevil (''Sitophilus zeamais''), among others. The boll weevil (''Anthonomus grandis'') attacks cotton crop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scarab Beetle
The family Scarabaeidae, as currently defined, consists of over 35,000 species of beetles worldwide; they are often called scarabs or scarab beetles. The classification of this family has undergone significant change. Several groups formerly treated as subfamilies have been elevated to family rank (e.g., Bolboceratidae, Geotrupidae, Glaresidae, Glaphyridae, Hybosoridae, Ochodaeidae, and Pleocomidae), and some reduced to lower ranks. The subfamilies listed in this article are in accordance with those in Catalog of Life (2023). Description Scarabs are stout-bodied beetles; most are brown or black in colour, but many, generally species that are diurnally active, have bright metallic colours, measuring between . The antennae of most species superficially seem to be knobbed (capitate), but the several segments comprising the head of the antenna are, as a rule, lamellate: they extend laterally into plates called lamellae that they usually keep compressed into a ball.

Ground Beetle
Ground beetles are a large, cosmopolitan distribution, cosmopolitan family (biology), family of beetles, the Carabidae, with more than 40,000 species worldwide, around 2,000 of which are found in North America and 2,700 in Europe. As of 2015, it is one of the 10 most species-rich animal families. They belong to the Adephaga. Members of the family are primarily Carnivore, carnivorous, but some members are Herbivore, herbivorous or Omnivore, omnivorous. Description and ecology Although their body shapes and coloring vary somewhat, most are shiny black or metallic and have ridged wing covers (elytra). The elytra are fused in some species, particularly the large Carabinae, rendering the beetles unable to fly. The species ''Mormolyce phyllodes'' is known as violin beetle due to their peculiarly shaped elytra. All carabids except the quite primitive flanged bombardier beetles (Paussinae) have a groove on their arthropod leg, fore leg tibiae bearing a comb of hairs used for cleaning the ...

Elateroidea
The Elateroidea are a large superfamily of beetles. It contains the familiar click beetles, fireflies, and soldier beetles and their relatives. It consists of about 25,000 species. Description Elateroidea is a morphologically diverse group, including hard-bodied beetles with 5 abdominal ventrites, soft-bodied beetles with 7-8 ventrites connected with membranes (formerly known as cantharoids), and beetles with intermediate forms. They have a range of sizes and colours, but in terms of shape, they are usually narrow and parallel-sided as adults. Many of the sclerotised elateroids ( Cerophytidae, Eucnemidae, Throscidae, Elateridae) have a clicking mechanism. This is a peg on the prothorax which fits into a cavity in the mesothorax. When a click beetle bends its body, the peg snaps into the cavity, causing the beetle's body to straighten so suddenly that it jumps into the air. Most beetles capable of bioluminescence are in the Elateroidea, in the families Lampyridae (~2000 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ripiphoridae
Ripiphoridae (formerly spelled Rhipiphoridae) is a cosmopolitan family of some 450 described species of beetles sometimes called "wedge-shaped beetles". Ripiphoridae are unusual among beetle families in that many species are hypermetamorphic parasitoids, an attribute that they share with the Meloidae. Members of the family differ in their choice of hosts, but most attack various species of bees or wasps, while some others attack cockroaches or beetles. Many species of Ripiphoridae have abbreviated elytra, and flabellate or pectinate antennae. Biology The subfamily Ripiphorinae parasitise bees and wasps (Hymenoptera), while Ripidiinae parasitises cockroaches (Blattodea) and Pelecotominae parasitises larvae of wood-boring beetles (Coleoptera). Species that attack bees typically lay their eggs on flowers. There the eggs hatch almost immediately into small planidial larvae and lie in wait for a visiting host. The planidium mounts the bee and rides it back to the hive. Ther ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cetoniinae
Flower chafers are a group of scarab beetles comprising the subfamily Cetoniinae. Many species are diurnal and visit flowers for pollen and nectar, or to browse on the petals. Some species also feed on fruit. The group is also called fruit and flower chafers, flower beetles and flower scarabs. There are around 4,000 species, many of them still undescribed. Ten tribes are presently recognized: Cetoniini, Cremastocheilini, Diplognathini, Goliathini, Gymnetini, Phaedimini, Schizorhinini, Stenotarsiini, Taenioderini, and Xiphoscelidini. The former tribes Trichiini and Valgini were elevated in rank to subfamily. The tribe Gymnetini is the biggest of the American tribes, and Goliathini contains the largest species, and is mainly found in the rainforest regions of Africa. Description Adult flower chafers are usually brightly coloured beetles, often metallic, and somewhat flattened in shape. The insertions of the antennae are visible from above, while the mandibles and lab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forewing
Insect wings are adult outgrowths of the insect exoskeleton that enable insects to fly. They are found on the second and third thoracic segments (the mesothorax and metathorax), and the two pairs are often referred to as the forewings and hindwings, respectively, though a few insects lack hindwings, even rudiments. The wings are strengthened by a number of longitudinal veins, which often have cross-connections that form closed "cells" in the membrane (extreme examples include the dragonflies and lacewings). The patterns resulting from the fusion and cross-connection of the wing veins are often diagnostic for different evolutionary lineages and can be used for identification to the family or even genus level in many orders of insects. Physically, some insects move their flight muscles directly, others indirectly. In insects with direct flight, the wing muscles directly attach to the wing base, so that a small downward movement of the wing base lifts the wing itself upward. Those ...

Buprestidae
Buprestidae is a family (biology), family of beetles known as jewel beetles or metallic wood-boring beetles because of their glossy Iridescence, iridescent colors. Larvae of this family are known as flatheaded borers. The family is among the largest of the beetles, with some 15,500 species known in 775 genera. In addition, almost 100 fossil species have been described. The larger and more spectacularly colored jewel beetles are highly prized by insect collectors. The elytra of some Buprestidae species have been traditionally used in beetlewing jewellery and decoration in certain countries in Asia, like India, Thailand and Japan. Description and ecology Shape is generally cylindrical or elongate to ovoid, with lengths ranging from , although most species are under . ''Catoxantha'', ''Chrysaspis (beetle), Chrysaspis'', ''Euchroma'' and ''Megaloxantha'' contain the largest species. A variety of bright colors are known, often in complicated patterns. The iridescence common to these ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
