Colletidae
The Colletidae are a family (biology), family of bees, and are often referred to collectively as plasterer bees or polyester bees, due to the method of smoothing the walls of their nest cells with secretions applied with their mouthparts; these secretions dry into a cellophane-like lining.C. D. Michener (2007) ''The Bees of the World'', 2nd Edition, pg. 133, Johns Hopkins University Press. The five subfamilies, 54 genera, and over 2000 species are all evidently solitary (with the known exception of but one species, ''Amphylaeus morosus''), though many nest in aggregations. Two of the subfamilies, Euryglossinae and Hylaeinae, lack the external pollen-carrying apparatus (the scopa (biology), scopa) that otherwise characterizes most bees, and instead carry the pollen in their crops. These groups, and most genera in this family, have liquid or semiliquid pollen masses on which the larvae develop. They can be found all over the world, but the most species live in South America and Aust ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ptiloglossa
''Ptiloglossa'' is a small genus of bees within the family Colletidae, endemic to the Americas. ''Ptiloglossa'' is one of the most common nocturnal groups of colletids. Distribution The species of ''Ptiloglossa'' are most diverse (over 50 species) in South America and Central America. Three species, '' Ptiloglossa arizonensis'', '' P. jonesi'', and '' P. mexicana'', occur in the Southwestern United States. Description ''Ptiloglossa'' consists of generally large, hairy species which are temporally-specialized crepuscular pollinators. They have greatly enlarged ocelli to assist them in flying under very low light levels. Life History They are active only at sundown ( vespertine) or more typically at pre-dawn (matinal). They often utilize a pollen-extraction behavior known as buzz pollination. Like most colletids, these bees have liquid larval provisions sealed inside a membranous, cellophane-like cell lining, and it is believed that yeasts in the liquid may act as the primary prot ...

Andrenidae
The Andrenidae (commonly known as mining bees) are a large, nearly cosmopolitan distribution, cosmopolitan family of solitary, ground-nesting bees. Most of the family's diversity is located in temperate or arid areas (warm temperate xeric). It includes some enormous genera (e.g., ''Andrena'' with over 1300 species, and ''Perdita (bee), Perdita'' with over 700). One of the subfamilies, Oxaeinae, is so different in appearance that they were typically accorded family status, but careful phylogenetic analysis reveals them to be an offshoot within the Andrenidae, very close to the Andreninae.C. D. Michener (2007) ''The Bees of the World'', 2nd Edition, Johns Hopkins University Press. Description The Andrenidae are typically small to moderate-sized bees, which often have scopa (biology), scopae on the basal segments of the leg in addition to the arthropod leg, tibia, and are commonly oligolectic (especially within the subfamily Panurginae). They can be separated from other bee familie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ocellus
A simple eye or ocellus (sometimes called a pigment pit) is a form of eye or an optical arrangement which has a single lens without the sort of elaborate retina that occurs in most vertebrates. These eyes are called "simple" to distinguish them from " compound eyes", which have multiple lenses. They are not necessarily simple in the sense of being uncomplicated or basic. The structure of an animal's eye is determined by the environment in which it lives, and the behavioural tasks it must fulfill to survive. Arthropods differ widely in the habitats in which they live, as well as their visual requirements for finding food or conspecifics, and avoiding predators. Consequently, an enormous variety of eye types are found in arthropods to overcome visual problems or limitations. Use of the term ''simple eye'' is flexible, and must be interpreted in proper context; for example, the eyes of most large animals are '' camera eyes'' and are sometimes considered "simple" because a sing ...

Matinal
Matutinal, matinal (in entomological writings), and matutine are terms used in the life sciences to indicate something of, relating to, or occurring in the early morning. The term may describe the morning activities of crepuscular animals that are significantly active during the predawn or early hours and which may or may not then be active again at dusk, in which case the animal is also said to be vespertinal/ vespertine. During the morning twilight period and shortly thereafter, these animals partake in important tasks, such as scanning for mates, mating, and foraging. Matutinal behaviour is thought to be adaptive because there may be less competition between species, and sometimes even a higher prevalence of food during these hours. It may also serve as an anti-predator adaptation by allowing animals to sit between the brink of danger that may come with diurnal and nocturnal activity. Etymology The word ''matutinal'' is derived from the Latin word ', meaning "of or pert ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vespertine (biology)
Vespertine is a term used in the life sciences to indicate something of, relating to, or occurring in the evening. In botany, a vespertine flower is one that opens or blooms in the evening. In zoology, the term is used for a creature that becomes active at dusk, such as bats and owls. Strictly speaking, however, the term means that activity ceases during the hours of full darkness and does not resume until the next evening. Activity that continues throughout the night should be described as nocturnal. Vespertine behaviour is a special case of crepuscular behaviour; like crepuscular activity, vespertine activity is limited to dusk rather than full darkness. Unlike vespertine activity, crepuscular activity may resume in dim twilight before dawn. A related term is matutinal, referring to activity limited to the dawn twilight. The word ''vespertine'' is derived from the Latin word ', an adjective meaning "evening". See also * Crypsis * Matutinal Matutinal, matinal (in entomo ...

Crepuscular
In zoology, a crepuscular animal is one that is active primarily during the twilight period, being matutinal (active during dawn), vespertine (biology), vespertine/vespertinal (active during dusk), or both. This is distinguished from diurnality, diurnal and nocturnality, nocturnal behavior, where an animal is active during the hours of daytime and of night, respectively. Some crepuscular animals may also be active by moonlight or during an overcast day. Matutinal animals are active only after dawn, and vespertine (biology), vespertine only before dusk. A number of factors affect the time of day an animal is active. Predation, Predators hunt when their prey is available, and prey try to avoid the times when their principal predators are at large. The temperature may be too high at midday or too low at night. Some creatures may adjust their activities depending on local competition. Etymology and usage The word ''crepuscular'' derives from the Latin ''wiktionary:crepusculum, cre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sensu Lato
''Sensu'' is a Latin word meaning "in the sense of". It is used in a number of fields including biology, geology, linguistics, semiotics, and law. Commonly it refers to how strictly or loosely an expression is used in describing any particular concept, but it also appears in expressions that indicate the convention or context of the usage. Common qualifiers ''Sensu'' is the ablative case of the noun ''sensus'', here meaning "sense". It is often accompanied by an adjective (in the same case). Three such phrases are: * – "in the strict sense", abbreviation ''s.s.'' or ''s.str.''; * – "in the broad sense", abbreviation ''s.l.''; * – "in a relaxed, generous (or 'ample') sense", a similar meaning to ''sensu lato''. Søren Kierkegaard uses the phrase ''sensu eminenti'' to mean "in the pre-eminent r most important or significantsense". When appropriate, comparative and superlative adjectives may also be used to convey the meaning of "more" or "most". Thus ''sensu stricto' ...

Melittidae
Melittidae is a small bee family, with over 200 described species in three subfamilies. The family has a limited distribution, with all described species restricted to Africa and the northern temperate zone. Fossil melittids have been found occasionally in Eocene amber deposits, including those of Oise, France and the Baltic amber. Evolution Early molecular work suggested that the family Melittidae was sister taxon, sister to all other bees, and also that it was paraphyletic. Because of this finding, it was suggested that the three subfamilies of Melittidae should be elevated to family status. Neither study included many melittids, due to their rarity. Later studies suggested that the family could still be monophyletic and a 2013 investigation including a greater number of melittid bees further supports this. Recent research has shown that Melittids have a lower extinction rate compared to other hymenopterans, yet this family is considered species-poor. This is attributed to a ...

Crabronidae
The Crabronidae is a large family of wasps within the superfamily Apoidea. Taxonomy and phylogeny This family has historically been treated as a subfamily in the now-defunct Spheciformes group under the family Sphecidae. The Spheciformes included well over 200 genera, containing well over 9000 species. Revision of these taxa resulted resulted in the restriction of the Sphecidae to what was once the subfamily Sphecinae. As a result, the former Crabroninae was elevated to family status as Crabronidae. Subsequent revision has further restricted the Crabronidae. Several of the subfamilies of the Crabronidae are often treated as families in their own right, as is true of the most recent phylogenies. Of these lineages of Apoidea, only three were not included within Crabronidae in the past: Ampulicidae, Sphecidae, and Anthophila. The following phylogenetic tree is based on Sann ''et al.'', 2018, which used phylogenomics to demonstrate that both the bees ( Anthophila) and the Sphe ...

Tongue
The tongue is a Muscle, muscular organ (anatomy), organ in the mouth of a typical tetrapod. It manipulates food for chewing and swallowing as part of the digestive system, digestive process, and is the primary organ of taste. The tongue's upper surface (dorsum) is covered by taste buds housed in numerous lingual papillae. It is sensitive and kept moist by saliva and is richly supplied with nerves and blood vessels. The tongue also serves as a natural means of cleaning the teeth. A major function of the tongue is to enable speech in humans and animal communication, vocalization in other animals. The human tongue is divided into two parts, an oral cavity, oral part at the front and a pharynx, pharyngeal part at the back. The left and right sides are also separated along most of its length by a vertical section of connective tissue, fibrous tissue (the lingual septum) that results in a groove, the median sulcus, on the tongue's surface. There are two groups of glossal muscles. The f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
