Lanugo (wasp)
''Lanugo'' is a genus of wasps belonging to the family (biology), family Ichneumonidae. The name refers to the Latin word ''lanugo'', meaning soft, downy hair, due to the hair found on species within this genus. This genus differs from the otherwise similar genus ''Compsocryptus'' by its "moderately short, straight ovipositor rather than a longer upcurved one, axillus vein closer to anal margin of hind wing, front size of areolet narrower." Species Species within this genus include: * ''Lanugo bicincta'' Townes, 1962 * ''Lanugo brunnipennis'' Townes, 1962 * ''Lanugo cesta'' (Say, 1863) * ''Lanugo deserti'' Townes, 1962 * ''Lanugo excincta'' Townes, 1962 * ''Lanugo ferrugata'' Townes, 1962 * ''Lanugo flavipennis'' Townes, 1962 * ''Lanugo fraternans'' (Cameron, 1885) * ''Lanugo hebetis'' (Cameron, 1885) * ''Lanugo longuria'' Townes, 1962 * ''Lanugo picta'' Townes, 1962 * ''Lanugo polita'' Townes, 1962 * ''Lanugo retentor'' (Brullé, 1846) * ''Lanugo schlingeri'' Townes, 1962 * ''L ...

Wasp
A wasp is any insect of the narrow-waisted suborder Apocrita of the order Hymenoptera which is neither a bee nor an ant; this excludes the broad-waisted sawflies (Symphyta), which look somewhat like wasps, but are in a separate suborder. The wasps do not constitute a clade, a complete natural group with a single ancestor, as bees and ants are deeply nested within the wasps, having evolved from wasp ancestors. Wasps that are members of the clade Aculeata can Stinger, sting their prey. The most commonly known wasps, such as yellowjackets and hornets, are in the family Vespidae and are Eusociality, eusocial, living together in a nest with an egg-laying queen and non-reproducing workers. Eusociality is favoured by the unusual haplodiploid system of sex-determination system, sex determination in Hymenoptera, as it makes sisters exceptionally closely related to each other. However, the majority of wasp species are solitary, with each adult female living and breeding independently ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lanugo Flavipennis
Lanugo is very thin, soft, usually unpigmented, downy hair that is sometimes found on the body of a fetus or newborn. It is the first hair to be produced by the fetal hair follicles, and it usually appears around sixteen weeks of gestation and is abundant by week twenty. It is normally shed before birth, around seven or eight months of gestation, but is sometimes present at birth. It disappears on its own within a few weeks. It is replaced by hair covering the same surfaces, which is called vellus hair. This hair is thinner and more difficult to see. The more visible hair that persists into adulthood is called terminal hair. It forms in specific areas and is hormone-dependent. The term is from the Latin ''lana'', meaning "wool." Humans Fetal development During human development, the lanugo grows on fetuses as a normal part of gestation, but it is usually shed and replaced by vellus hair at about thirty-three to thirty-six weeks of gestational age. As the lanugo is shed from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opi ...
