Scarab Beetle Anomala lucicola

Scarab Beetle Anomala lucicola and the family Scarabaeidae as currently defined consists of over 30,000 species of beetles worldwide, often called scarabs or scarab beetles. The classification of Scarab Beetle Anomala lucicola is fairly unstable, with numerous competing theories, and new proposals appearing quite often. Many of the subfamilies listed here probably will not be recognized very much longer, as they will likely be reduced in status below subfamily rank, or elevated to family status (the latter is most likely, e.g., with the family “Melolonthidae” already appearing in some recent classifications). Other families have been removed recently, and are nearly universally accepted (e.g., Pleocomidae, Glaresidae, Glaphyridae, Ochodaeidae, Geotrupidae, and Bolboceratidae).

Scarab Beetle Anomala lucicola Descriprion

Scarab Beetle Anomala lucicola are stout-bodied beetles, many with bright metallic colours, measuring between 1.5 and 160 mm. They have distinctive, clubbed antennae composed of plates called lamellae that can be compressed into a ball or fanned out like leaves to sense odours. The front legs of many species are broad and adapted for digging. The C-shaped larvae, called grubs, are pale yellow or white. Most adult Scarab Beetle Anomala lucicola are nocturnal, although the flower chafers (Cetoniinae) and many leaf chafers (Rutelinae) are active during the day. The grubs mostly live underground or under debris, so are not exposed to sunlight. Many scarabs are scavengers that recycle dung, carrion, or decaying plant material. Others, such as the Japanese beetle, are devastating agricultural pests.

Some of the well-known Scarab Beetle Anomala lucicola from the Scarabaeidae are Japanese beetles, dung beetles, June beetles, rose chafers (Australian, European, and North American), rhinoceros beetles, Hercules beetles and Goliath beetles.  Several members of this family have structurally coloured shells which act as left-handed circular polarisers; this was the first-discovered example of circular polarization in nature.

Scarab Beetle Anomala lucicola are a group of insects that form the order Coleoptera. The word “coleoptera” is from the Greek κολεός, koleos, meaning “sheath”; and πτερόν, pteron, meaning “wing”, thus “sheathed wing”, because most beetles have two pairs of wings, the front pair, the “elytra”, being hardened and thickened into a shell-like protection for the rear pair and the beetle’s abdomen. The order contains more species than any other order, constituting almost 25% of all known life-forms. About 40% of all described insect species are beetles (about 400,000 species), and new species are discovered frequently. The largest taxonomic family, the Curculionidae (the weevils or snout beetles), also belongs to this order.

The diversity of Scarab Beetle Anomala lucicola is very wide-ranging. They are found in almost all types of habitats, but are not known to occur in the sea or in the polar regions. They interact with their ecosystems in several ways. They often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are prey of various animals including birds and mammals. Certain species are agricultural pests, such as the Colorado potato beetle Leptinotarsa decemlineata, the boll weevil Anthonomus grandis, the red flour beetle Tribolium castaneum, and the mungbean or cowpea beetle Callosobruchus maculatus, while other species of beetles are important controls of agricultural pests. For example, beetles in the family Coccinellidae (“ladybirds” or “ladybugs”) consume aphids, scale insects, thrips, and other plant-sucking insects that damage crops.

Scarab Beetle Anomala lucicola and species in the order Coleoptera are generally characterized by a particularly hard exoskeleton and hard forewings (elytra, singular elytron). These elytra distinguish beetles from most other insect species, except for a few species of Hemiptera. The beetle’s exoskeleton is made up of numerous plates called sclerites, separated by thin sutures. This design creates the armored defenses of the beetle while maintaining flexibility. The general anatomy of a beetle is quite uniform, although specific organs and appendages may vary greatly in appearance and function between the many families in the order. Like all insects, Scarab Beetle Anomala lucicola’ bodies are divided into three sections: the head, the thorax, and the abdomen. Coleopteran internal morphology is similar to other insects, although there are several examples of novelty. Such examples include species of water beetle which use air bubbles in order to dive under the water, and can remain submerged thanks to passive diffusion as oxygen moves from the water into the bubble.

Scarab Beetle Anomala lucicola are endopterygotes, which means that they undergo complete metamorphosis, a biological process by which an animal physically develops after birth or hatching, undergoing a series of conspicuous and relatively abrupt change in the its body structure. Coleopteran species have an extremely intricate behavior when mating, using such methods as pheromones for communication to locate potential mates. Males may fight for females using very elongated mandibles, causing a strong divergence between males and females in sexual dimorphism.

Scarab Beetle Anomala lucicola Etymology

Coleoptera comes from the Greek koleopteros, literally “sheath-wing”, from koleos meaning “sheath”, and pteron, meaning “wing”. The name was given to the group by Aristotle for their elytra, hardened shield-like forewings. The English name “beetle” comes from the Old English word bitela, literally meaning small biter, deriving from the word bitel, which means biting. This word is related to the word bītan (to bite) The name also derives from the Middle English word betylle from Old English bitula (also meaning to bite). Another Old English name for beetle is ceafor, chafer, used in names such as cockchafer, from the Proto-Germanic *kabraz- (compare German Käfer). These terms have been in use since the 12th century. In addition to names including the words “beetle” or “chafer”, many groups of Coleoptera have common names such as fireflies, June bugs, ladybugs and weevils.

Scarab Beetle Anomala lucicola Taxonomy

The Coleopterans include more species than any other order, constituting almost 25% of all known types of animal life forms. About 450,000 species of beetles occur – representing about 40% of all known insects. Such a large number of species poses special problems for classification, with some families consisting of thousands of species and needing further division into subfamilies and tribes. This immense number of species allegedly led evolutionary biologist J. B. S. Haldane to quip, when some theologians asked him what could be inferred about the mind of the Creator from the works of His Creation, that God displayed “an inordinate fondness for beetles”.

Polyphaga is the largest suborder, containing more than 300,000 described species in more than 170 families, including rove beetles (Staphylinidae), scarab beetles (Scarabaeidae), blister beetles (Meloidae), stag beetles (Lucanidae) and true weevils (Curculionidae). These beetles can be identified by the presence of cervical sclerites (hardened parts of the head used as points of attachment for muscles) absent in the other suborders. The suborder Adephaga contains about 10 families of largely predatory beetles, includes ground beetles (Carabidae), Dytiscidae and whirligig beetles (Gyrinidae). In these beetles, the testes are tubular and the first abdominal sternum (a plate of the exoskeleton) is divided by the hind coxae (the basal joints of the beetle’s legs). Archostemata contains four families of mainly wood-eating beetles, including reticulated beetles (Cupedidae) and the telephone-pole beetle. Myxophaga contains about 100 described species in four families, mostly very small, including Hydroscaphidae and the genus Sphaerius.
