Butterfly Net
A butterfly net (sometimes called an aerial insect net) is one of several kinds of nets used to collect insects. The entire bag of the net is generally constructed from a lightweight mesh to minimize damage to delicate butterfly wings. Other types of nets used in insect collecting include beat nets, aquatic nets, and sweep nets. Nets for catching different insects have different mesh sizes. Aquatic nets usually have bigger, more 'open' mesh. Catching small aquatic creatures usually requires an insect net. The mesh is smaller and can capture more.

Net (device)
A net comprises Thread (yarn), threads or yarns knotted and twisted into a grid-like structure which blocks the passage of large items, while letting small items and fluids pass. It requires less material than something sheet-like, and provides a degree of Transparency and translucency, transparency, as well as flexibility and lightness. Nets have been constructed by human beings since at least the Mesolithic period for use in capturing or retaining things. Their open structure provide lightness and flexibility that allow them to be carried and manipulated with relative ease, making them valuable for methodical tasks such as hunting, fishing, sleeping, and carrying. History The oldest nets found are from the Mesolithic era, but nets may have existed in the Upper Paleolithic, Upper Paleolithic era. Nets are typically made of perishable materials and leave little archeological record. Some nets are preserved in ice or bogs, and there are also Use of animals during the Gravettian ...

Butterfly
Butterflies are winged insects from the lepidopteran superfamily Papilionoidea, characterized by large, often brightly coloured wings that often fold together when at rest, and a conspicuous, fluttering flight. The oldest butterfly fossils have been dated to the Paleocene, about 56 million years ago, though molecular evidence suggests that they likely originated in the Cretaceous. Butterflies have a four-stage life cycle, and like other holometabolous insects they undergo complete metamorphosis. Winged adults lay eggs on the food plant on which their larvae, known as caterpillars, will feed. The caterpillars grow, sometimes very rapidly, and when fully developed, pupate in a chrysalis. When metamorphosis is complete, the pupal skin splits, the adult insect climbs out, expands its wings to dry, and flies off. Some butterflies, especially in the tropics, have several generations in a year, while others have a single generation, and a few in cold locations may take s ...

Insect Collecting
Insect collecting refers to the collection of insects and other arthropods for scientific study or as a hobby.Manoj K., Ranjan R., Sinha M. P., Dhan A., Naaz F., Khanum G., Rani K. A., Sharma S., Raipat B. S. (2022). A Review on Insect Collection and Preservation Techniques. European Journal of Pharmaceutical and Medical Research, 9(7): 233-239. Most insects are small and the majority cannot be identified without the examination of minute morphological characters, so entomologists often make and maintain insect collections. Very large collections are preserved in natural history museums or universities where they are maintained and studied by specialists. Many college courses require students to form small collections. There are also amateur entomologists and collectors who keep collections. Historically, insect collecting has been widespread and was in the Victorian age a very popular educational hobby. Insect collecting has left traces in European cultural history, literatu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beating Net .
The insect beating net was devised by George Carter Bignell.
{{Short description, Device for catching insects A beating net, also known as beating sheet, beat sheet or beating tray, is a device used to collect insects. It consists of a white cloth stretched out on a circular or rectangular frame which may be dismantled for transport. The beating tray is held under a tree or shrub and the foliage is then shaken or beaten with a stick. Insects fall from the plant and land on the cloth. They can then be examined or collected using a pooter In entomology, an aspirator, also known as a pooter, is a device used in the collection of insects, crustaceans or other small, fragile organisms, usually for scientific purposes.

Collecting
The hobby of collecting includes seeking, locating, acquiring, organizing, cataloging, displaying, storing, and maintaining items that are of interest to an individual ''collector''. Collections differ in a wide variety of respects, most obviously in the nature and scope of the objects contained, but also in purpose, presentation, and so forth. The range of possible subjects for a collection is practically unlimited, and collectors have realised a vast number of these possibilities in practice, although some are much more popular than others. In collections of manufactured items, the objects may be antique or simply collectable. Antiques are collectable items at least 100 years old, while other collectables are arbitrarily recent. The word ''vintage'' describes relatively old collectables that are not yet antiques. Collecting is a childhood hobby for some people, but for others, it is a lifelong pursuit or something started in adulthood. Collectors who begin early in life oft ...

Entomology Equipment
Entomology (from Ancient Greek ἔντομον (''éntomon''), meaning "insect", and -logy from λόγος (''lógos''), meaning "study") is the branch of zoology that focuses on insects. Those who study entomology are known as entomologists. In the past, the term ''insect'' was less specific, and historically the definition of entomology would also include the study of animals in other arthropod groups, such as arachnids, myriapods, and crustaceans. The field is also referred to as insectology in American English, while in British English insectology implies the study of the relationships between insects and humans. Over 1.3million insect species have been described by entomology. History Entomology is rooted in nearly all human cultures from prehistoric times, primarily in the context of agriculture (especially biological control and beekeeping). The natural Roman philosopher Pliny the Elder (23–79 CE) wrote a book on the kinds of insects, while the scientist of Kufa, ...
