Charles Robertson (American Entomologist)
Charles Robertson (1858–1935) was an American entomologist specializing in bees. He carried out what is still the single most intensive study of flower-visiting insects of a single locality, culminating in a 221-page book published in 1928 under the title ''Flowers and Insects''. Personal life Charles Robertson was born to parents Dr. William Robertson (1803 -1880) and Nancy Robertson, née Halliday (b.1821), married October 18, 1842. His father, William, was a physician turned farmer and general merchandiser, and his mother, Nancy, was the daughter of a reverend.

Entomology
Entomology () is the science, scientific study of insects, a branch of zoology. 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. This wider meaning may still be encountered in informal use. Like several of the other fields that are categorized within zoology, entomology is a taxon-based category; any form of scientific study in which there is a focus on insect-related inquiries is, by definition, entomology. Entomology therefore overlaps with a cross-section of topics as diverse as molecular genetics, behavior, neuroscience, biomechanics, biochemistry, systematics, physiology, developmental biology, ecology, morphology (biology), morphology, and paleontology. Over 1.3 million insect species have been described, more than two-thirds of all known species. Some insect species date back to around 400 million years ago. Th ...

Sphecodes Cressonii
''Sphecodes'' is a genus of bees from the family Halictidae, the majority of which are black and red in colour and are colloquially known as blood bees. ''Sphecodes'' bees are kleptoparasitic on other bees, especially bees in the genera ''Lasioglossum'', ''Halictus'' and ''Andrena''. The adults consume nectar, but because they use other bees' provisions to feed their offspring they do not collect pollen. Distribution ''Sphecodes'' is a cosmopolitan genus with species represented on every continent. The genus is also very species rich, with 21 species described from Siberia, 33 species from Central Europe, 17 species from the Indian region, 26 from the Arabian Peninsula and surrounding region, and 21 from Southeast Asia. The genus is only represented in Australia in the northeast, with the species ''Sphecodes albilabris'' being thought to have been introduced to both Australia and the United States by accident. Species There are over 300 known species in the genus ''Sphecodes''. ...

People From Carlinville, Illinois
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of ...

Nomada Ovata
With over 850 species, the genus ''Nomada'' is one of the largest genera in the family Apidae, and the largest genus of kleptoparasitic "cuckoo bees." Kleptoparasitic bees are so named because they enter the nests of a host and lay eggs there, stealing resources that the host has already collected. The name "''Nomada''" is derived from the Greek word ''nomas ( νομάς''), meaning "roaming" or "wandering." ''Nomada'' parasitize many different types of bees as hosts, primarily the genus ''Andrena,'' but also '' Agapostemon, Melitta, Eucera'' and ''Exomalopsis''. As parasites, they lack a pollen-carrying scopa, and are mostly hairless, as they do not collect pollen to feed their offspring. Like non-parasitic bees, adults are known to visit flowers and feed on nectar. Given the lack of scopa and general behavior, they are considered poor pollinators. Appearance and identification They are often extraordinarily wasp-like in appearance, with red, black, and yellow colors prevail ...

Carlinville, Illinois
Carlinville is a city and the county seat of Macoupin County, Illinois, United States. It is also the home of Blackburn College, a small college affiliated with the Presbyterian church, and the former home of Prairie Farms Dairy. As of the 2020 census, the population of Carlinville was 5,710. History Carlinville is named for Thomas Carlin, 7th Governor of Illinois, who as a member of the state legislature was instrumental in creating Macoupin County. Carlinville has long been a site of Illinois history, and played host to many presidential hopefuls via campaign stops at a time in American history when railway routes produced many visits by politicians. Perhaps the largest and most important hallmark of Carlinville's history is its courthouse, the largest built outside of New York City at the time of its erection. Built in 1870 and designed by famous state capitol building architect Elijah E. Myers, the construction of Carlinville's courthouse produced its candidacy for the ...
