Tenebrio Obscurus
''Tenebrio obscurus'', or the dark mealworm beetle, is a species of darkling beetle. The larvae, when used as feeder insects for reptile and amphibian pets, are known as mini mealworm. These insects should not be confused with younger mealworms (''Tenebrio molitor'') or with the confused flour beetle ('' Tribolium confusum''), which is also occasionally used as a reptile feeder insect. Mini mealworms would probably remain largely unknown, if not for the reptile pet industry. In the search for easy to raise insects to use as food for captive reptiles and amphibians, mini mealworms have recently attracted interest as an ideal food item for smaller species. The larvae resemble very small mealworms, about ½ to ¾ inch (12 to 19 mm) in size. Once they reach adult size, the larvae pupa A pupa ( la, pupa, "doll"; plural: ''pupae'') is the life stage of some insects undergoing transformation between immature and mature stages.

Johan Christian Fabricius
Johan Christian Fabricius (7 January 1745 – 3 March 1808) was a Danish zoologist, specialising in "Insecta", which at that time included all arthropods: insects, arachnids, crustaceans and others. He was a student of Carl Linnaeus, and is considered one of the most important entomologists of the 18th century, having named nearly 10,000 species of animals, and established the basis for the modern insect classification. Biography Johan Christian Fabricius was born on 7 January 1745 at Tønder in the Duchy of Schleswig, where his father was a doctor. He studied at the gymnasium at Altona and entered the University of Copenhagen in 1762. Later the same year he travelled together with his friend and relative Johan Zoëga to Uppsala, where he studied under Carl Linnaeus for two years. On his return, he started work on his , which was finally published in 1775. Throughout this time, he remained dependent on subsidies from his father, who worked as a consultant at Frederiks Hospita ...

Darkling Beetle
Darkling beetle is the common name for members of the beetle family Tenebrionidae. The number of species in the Tenebrionidae is estimated at more than 20,000 and the family is cosmopolitan in distribution. Taxonomy ''Tenebrio'' is the Latin generic name that Carl Linnaeus assigned to some flour beetles in his ''10th edition of Systema Naturae'' 1758-59. The word means "seeker of dark places" (or figuratively a trickster); an English language analogy is "darkling". Numerous Tenebrionidae species do inhabit dark places, however, there are many species in genera such as ''Stenocara'' and ''Onymacris'', which are active by day and inactive at night. The family covers a varied range of forms, such that classification presents great difficulties. These eleven subfamilies were listed in the 2021 review by Bouchard, Bousquet, ''et al.'', updating a similar catalog from 2005.Bouchard, Patrice. Lawrence, John F. Davies, Anthony E.

Larva
A larva (; plural larvae ) is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle. The larva's appearance is generally very different from the adult form (''e.g.'' caterpillars and butterflies) including different unique structures and organs that do not occur in the adult form. Their diet may also be considerably different. Larvae are frequently adapted to different environments than adults. For example, some larvae such as tadpoles live almost exclusively in aquatic environments, but can live outside water as adult frogs. By living in a distinct environment, larvae may be given shelter from predators and reduce competition for resources with the adult population. Animals in the larval stage will consume food to fuel their transition into the adult form. In some organisms like polychaetes and barnacles, adults are immobil ...

Feeder Insect
Live food is living animals used as food for other carnivorous or omnivorous animals kept in captivity; in other words, small preys (such as insects, small fish or rodents) fed alive to larger predators kept either in a zoo or as a pet. Live food is commonly used as feed for a variety of species of exotic pets and zoo animals, ranging from crocodilians (crocodiles and alligators) to various snakes, turtles, lizards and frogs, but also including other non- reptilian, non-amphibian species such as birds and mammals (for instance, pet skunks, which are omnivorous mammals, can technically be fed a limited amount of live food, though this is not known to be a common practice). Common live food ranges from insects (e.g. crickets, used as an inexpensive form of feed for reptiles such as bearded dragons and commonly available in pet stores for this reason; other examples are cockroaches, locusts, waxworms and mealworms), worms (e.g. earthworms) and crustaceans, to small birds (e.g. ch ...

Tenebrio Molitor
Mealworms are the larval form of the yellow mealworm beetle, ''Tenebrio molitor'', a species of darkling beetle. Like all holometabolic insects, they go through four life stages: egg, larva, pupa, and adult. Larvae typically measure about or more, whereas adults are generally between in length. Reproduction The mealworm beetle breeds prolifically. Males insert sperm packets with their aedeagus. Within a few days the female burrows into soft ground and lays eggs. Over her lifespan, a female will, on average, lay about 500 eggs. After 4 to 19 days the eggs hatch. During the larval stage, the mealworms feed on vegetation and dead insects and molt between each larval stage, or instar (9 to 20 instars). After the final molt, they pupate. The new pupa is whitish and turns brown over time. After 3 to 30 days, depending on environmental conditions such as temperature, it emerges as an adult beetle. Sex pheromones A sex pheromone released by male mealworms has been identified. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Confused Flour Beetle
The confused flour beetle (''Tribolium confusum''), a type of darkling beetle known as a flour beetle, is a common pest insect known for attacking and infesting stored flour and grain. They are one of the most common and most destructive insect pests for grain and other food products stored in silos, warehouses, grocery stores, and homes. The "confused" in the beetle's name is due to it being confused with the red flour beetle, not because of its walking pattern.Baldwin R, Fasulo TR. (2010). Confused flour beetle, ''Tribolium confusum'' Jacquelin du Val, and red flour beetle, ''Tribolium castaneum'' (Herbst). ''Featured Creatures''. (15 April ...

Reptile Pet
Herpetoculture is the keeping of live reptiles and amphibians in captivity, whether as a hobby or as a commercial breeding operation. "Herps" is an informal term for both reptiles and amphibians, shortened from the scientific umbrella term “herptiles”. It is undertaken by people of all ages and from all walks of life, including career herpetologists, professional reptile or amphibian breeders, and casual hobbyists. Etymology The origin of the word "herpetoculture" is credited to Tom Huff, who devised the word to distinguish what he, as a self-described "herpetoculturist", was doing—working to keeping reptiles and amphibians alive and healthy—from what herpetologists of that era were generally doing, namely, collecting specimens for preservation in museum collections. The word itself comes from the Greek language origin , which means "to creep".

Pupa
A pupa ( la, pupa, "doll"; plural: ''pupae'') is the life stage of some insects undergoing transformation between immature and mature stages. Insects that go through a pupal stage are holometabolous: they go through four distinct stages in their life cycle, the stages thereof being egg, larva, pupa, and imago. The processes of entering and completing the pupal stage are controlled by the insect's hormones, especially juvenile hormone, prothoracicotropic hormone, and ecdysone. The act of becoming a pupa is called pupation, and the act of emerging from the pupal case is called eclosion or emergence. The pupae of different groups of insects have different names such as ''chrysalis'' for the pupae of butterflies and ''tumbler'' for those of the mosquito family. Pupae may further be enclosed in other structures such as cocoons, nests, or shells. Position in life cycle The pupal stage follows the larval stage and precedes adulthood (''imago'') in insects with complete metamorphosi ...

Pet Foods
Pet food is animal feed intended for consumption by pets. Typically sold in pet stores and supermarkets, it is usually specific to the type of animal, such as dog food or cat food. Most meat used for animals is a byproduct of the human food industry, and is not regarded as "human grade".Hickman, LeoBritain's problem with pets ''The Guardian'', November 13, 2009. In 2019, the world pet food market was valued at US$87.08 billion and is projected to grow to US$113.2 billion by the year 2024. The pet food market is dominated by five major companies, as of 2020: Mars, Inc., Nestle Purina Petcare, J. M. Smucker, Hill's Pet Nutrition, Inc. (owned by Colgate-Palmolive), and Blue Buffalo Co. Ltd (owned by General Mills). Industry In the United States, pet-food sales in 2016 reached an all-time high of $28.23 billion. Mars is the leading company in the pet food industry, making about $17 billion annually in pet-care products. Online sales of pet food are increasing and contributing to ...

Beetles Described In 1792
Beetles are insects that form the Taxonomic rank, order Coleoptera (), in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, Elytron, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungus, fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops.
