Hesperiidae
Skippers are a group of butterflies placed in the family Hesperiidae within the order Lepidoptera (moths and butterflies). They were previously placed in a separate superfamily, Hesperioidea, but have since been placed in the superfamily Papilionoidea (the butterflies). They are named for their quick, darting flight habits. Most have their antenna tips modified into narrow, hook-like projections. Moreover, skippers mostly lack wing-coupling structure available in most moths. More than 3500 species of skippers are recognized, and they occur worldwide, but with the greatest diversity in the Neotropical regions of Central and South America.Ackery et al. (1999) Description and systematics Traditionally, the Hesperiidae were placed in a monotypic superfamily Hesperioidea, because they are morphologically distinct from other Rhopalocera (butterflies), which mostly belong to the typical butterfly superfamily Papilionoidea. The third and rather small butterfly superfamily is the moth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhopalocera
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 seve ...

Western Blue Policeman (Pyrrhiades Lucagus)
''Pyrrhiades'' is a genus of butterflies in the family Hesperiidae. It contains only one species, ''Pyrrhiades lucagus'', the western blue policeman, which is found in Liberia, Ivory Coast and Ghana Ghana, officially the Republic of Ghana, is a country in West Africa. It is situated along the Gulf of Guinea and the Atlantic Ocean to the south, and shares borders with Côte d’Ivoire to the west, Burkina Faso to the north, and Togo to t ....

Hesperia Comma
''Hesperia comma'', the silver-spotted skipper or common branded skipper, is a butterfly of the family Hesperiidae. It is known as silver-spotted skipper in Europe and common branded skipper in North America where the butterfly ''Epargyreus clarus'', a spread-winged skipper, also has the common name of "silver-spotted skipper". Appearance, behaviour and distribution Often confused with the large skipper ''Ochlodes sylvanus'', this species is easily distinguished by the numerous white spots on the underside hindwings, and the tips of the upper forewings tend to be darker than those of the large skipper. Also their flight periods rarely overlap; in Britain the large skipper has all but finished when the silver-spotted takes to the wing in August. The silver-spotted skipper prefers warm calcareous sites and has a wide distribution as far south as North Africa, northwards throughout Europe to the Arctic and eastwards across Asia to China and Japan. It also has subspecies in North Am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red-underwing Skipper (Spialia Sertorius)
''Spialia sertorius'', commonly known as the red-underwing skipper, is a butterfly of the family Hesperiidae. Description The red-underwing skipper can be confused with the species of the genus ''Pyrgus''. The underside has a cinnamon-red to yellowish base tone, while it is primarily greenish to brownish in the ''Pyrgus'' species. Since this coloring is less evident in older butterflies (and deviations occur), the characteristic arrangement of the spots on the underside of the hind wing should always be used to determine. On the upper side of the forewing, there is a series of small, distinctly bright spots in the submarginal bandage, which runs in a regular flat curve to the front edge. The four areas of the post-discal region further towards the wing base are also in a row, while in the species of the genus ''Pyrgus,'' only three are side by side, and the fourth is disengaged. The wingspan is 22-26 mm. (MHNT) Spialia sertorius - Bossey, Haute-Savoie, France - male dorsal.jpg, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moth-butterflies
Hedylidae, the "American moth-butterflies", is a Family (biology), family of insects in the order Lepidoptera, formerly representing the superfamily Hedyloidea. They have traditionally been viewed as an Extant taxon, extant sister group of the butterfly superfamily Papilionoidea, but a 2014 Phylogenetics, phylogenetic analysis has suggested Hedylidae is a subgroup of Papilionoidea, and not a sister group, and are more accurately referred to as butterflies rather than moths. They are represented by a single Neotropical genus, ''Macrosoma'', with 35 currently recognized species. Taxonomy and systematics Hedylidae were previously treated as a Tribe (biology), tribe of Geometridae: Oenochrominae, the "Hedylicae". Prout considered they might even merit treatment as their own family. Scoble first considered them to be a hitherto unrecognised group of butterflies and also suggested Hedylidae might possibly constitute the sister group of the "true" butterflies (Papilionoidea), rather than ...

Pierre André Latreille
Pierre André Latreille (; 29 November 1762 – 6 February 1833) was a French zoology, zoologist, specialising in arthropods. Having trained as a Roman Catholic priest before the French Revolution, Latreille was imprisoned, and only regained his freedom after recognising a rare beetle species he found in the prison, ''Necrobia ruficollis.'' He published his first important work, , in 1796, and was eventually employed by the . His foresighted work on arthropod systematics and Taxonomy (biology), taxonomy gained him respect and accolades, including being asked to write the volume on insects for George Cuvier's monumental work, , the only part not by Cuvier himself. Latreille was considered the foremost entomology, entomologist of his time, and was described by one of his pupils as "the prince of entomologists". Biography Early life Pierre André Latreille was born on 29 November 1762 in the town of Brive-la-Gaillarde, Brive, then in the Limousin (province), province of Limousi ...

Crochet Hook
A crochet hook (or crochet needle) is an implement used to make loops in thread or yarn and to interlock them into crochet stitches. It is a round shaft pointed on one end, with a lateral groove behind it. The point eases the insertion of the hook through the material being crocheted and the groove makes it possible to pull a loop back through the material. The shaft is then divided into a working area that determines the hook's nominal diameter and ensures the uniform sizing of the loops formed on it, and a handle. Construction Crochet appeared as a distinct textile arts, textile art during the early 19th century, and many crochet hooks survive from that period. These can be sorted into two groups, the one with thin steel hooks that are set into separate handles, and the other including single-piece hooks made in a variety of materials. The distinction between steel and other hooks persists to the present day, although all are now commonly of single-piece construction. A variety ...

Pupa
A pupa (; : 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, or in some cases a prepupal stage, and precedes adulthood ('' imago'') in insects with compl ...

Antenna (biology)
An antenna (plural: antennae) is one of a pair of appendages used for Sensory system, sensing in arthropods. Antennae are sometimes referred to as ''feelers''. Antennae are connected to the first one or two Segmentation (biology), segments of the arthropod head. They vary widely in form but are always made of one or more jointed segments. While they are typically sensory organs, the exact nature of what they sense and how they sense it is not the same in all groups. Functions may variously include sensing tactition, touch, air motion, heat, vibration (sound), and especially insect olfaction, smell or gustation, taste. Antennae are sometimes modified for other purposes, such as mating, brooding, swimming, and even anchoring the arthropod to a substrate (biology), substrate. Larval arthropods have antennae that differ from those of the adult. Many crustaceans, for example, have free-swimming larvae that use their antennae for swimming. Antennae can also locate other group members i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compound Eye
A compound eye is a Eye, visual organ found in arthropods such as insects and crustaceans. It may consist of thousands of ommatidium, ommatidia, which are tiny independent photoreception units that consist of a cornea, lens (anatomy), lens, and photoreceptor cells which distinguish brightness and color. The image perceived by this arthropod eye is a combination of inputs from the numerous ommatidia, which are oriented to point in slightly different directions. Compared with single-aperture eyes, compound eyes have poor image resolution; however, they possess a very large view angle and the ability to detect fast movement and, in some cases, the Polarization (waves), polarization of light. Because a compound eye is made up of a collection of ommatidia, each with its own lens, light will enter each ommatidium instead of using a single entrance point. The individual light receptors behind each lens are then turned on and off due to a series of changes in the light intensity during mov ...

Moth
Moths are a group of insects that includes all members of the order Lepidoptera that are not Butterfly, butterflies. They were previously classified as suborder Heterocera, but the group is Paraphyly, paraphyletic with respect to butterflies (suborder Rhopalocera) and neither subordinate taxon is used in modern classifications. Moths make up the vast majority of the order. There are approximately 160,000 species of moth, many of which have yet to be described. Most species of moth are nocturnal, although there are also crepuscular and Diurnal animal, diurnal species. Differences between butterflies and moths While the Butterfly, butterflies form a monophyly, monophyletic group, the moths, comprising the rest of the Lepidoptera, do not. Many attempts have been made to group the superfamilies of the Lepidoptera into natural groups, most of which fail because one of the two groups is not monophyletic: Microlepidoptera and Macrolepidoptera, Heterocera and Rhopalocera, Jugatae a ...
