Frank Craighead Sr.
Frank Cooper Craighead Sr. (1890-1982) was an American entomologist and naturalist, who specialized among other subjects on the larvae of Coleoptera. Craighead worked as principal entomologist for the United States Department of Agriculture and (co)authored many books on various environmentalist subjects, but is probably best known for the book ''"An illustrated synopsis of the principal larval forms of the order Coleoptera"'' that he co authored with Adam Giede Böving in 1930 with some 20 subsequent editions until 1953. Personal life Craighead married the biologist technician Carolyn Johnson and together they had three children, twin sons and a daughter. The twins Frank and John became renowned naturalists in their own right as well (famous for their work on grizzly bear The grizzly bear (''Ursus arctos horribilis''), also known as the North American brown bear or simply grizzly, is a population or subspecies of the brown bear inhabiting North America.

Entomologist
Entomology () is the 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, 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. They have many kinds of intera ...

Coleoptera
Beetles are insects that form the order Coleoptera (), in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops. Beetles typically have a particularly hard e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Adam Giede Böving (July 31, 1869 – March 16, 1957) was a Danish-American entomologist and zoologist. He was a specialist in the study of the larvae of the order Coleoptera and the author of a series of descriptions on their early stages of development. Biography Adam Böving was born at Sæby in Vendsyssel, Denmark. He was the eldest child of Niels Orten Mathias Bøving (1838-1923) and Louise Augustine Ottilia (Gjede) Bøving (1838-99. His father was a school headmaster and later church vicar. After matriculation from Aalborg University, he continued his studies of zoology at the University of Copenhagen where he earned his Ph.D. in 1888. From 1902 to 1903 he worked as assistant curator of entomology in the University of Copenhagen Zoological Museum of Copenhagen. He immigrated to the United States in 1913 to become a member of the Bureau of Entomology, a division of United States Department of Agriculture (USDA).

Frank And John Craighead
Frank Cooper Craighead Jr. (August 14, 1916 – October 21, 2001) and John Johnson Craighead (August 14, 1916 – September 18, 2016), twin brothers, were American Conservation movement, conservationists, naturalists, and researchers who made important contributions to the studies of falconry and grizzly bear biology. The brothers were born in Washington, D.C. where both graduated from Western High School in 1935. The brothers began collecting and identifying animals and plants they found alongside the Potomac River, Potomac and soon expanded their interests to birds and hawks. They traveled west in 1934 to begin studying falconry. After World War II, during which they were employed as survival trainers, they each married and resumed their work in falconry. During the 1950s, the Craighead brothers expanded their work to other animals, including many species living in and around Yellowstone National Park, Yellowstone, and eventually separated. In 1959 their careers merged again, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grizzly Bear
The grizzly bear (''Ursus arctos horribilis''), also known as the North American brown bear or simply grizzly, is a population or subspecies of the brown bear inhabiting North America. In addition to the mainland grizzly (''Ursus arctos horribilis''), other morphological forms of brown bear in North America are sometimes identified as grizzly bears. These include three living populations—the Kodiak bear (''U. a. middendorffi''), the Kamchatka bear (''U. a. beringianus''), and the peninsular grizzly (''U. a. gyas'')—as well as the extinct California grizzly (''U. a. californicus''†), Mexican grizzly (formerly ''U. a. nelsoni''†), and Ungava-Labrador grizzly (formerly ''U. a. ungavaesis''†). On average, grizzly bears near the coast tend to be larger while inland grizzlies tend to be smaller. The Ussuri brown bear (''U. a. lasiotus''), inhabiting Russia, Northern China, Japan, and Korea, is sometimes referred to as the "black grizzly", although it is no more closely ...
