He worked in a factory to help the family and graduated from the Henry Ford Trade School, working as a tool-and-die maker and later being a superintendent of a workshop. He took an interest in entomology as an amateur and when the US Department of Agriculture announced a vacancy, he joined as an agricultural research technician at Washington, D.C.

Tephritidae
The Tephritidae are one of two fly families referred to as fruit flies, the other family being the Drosophilidae. The family Tephritidae does not include the biological model organisms of the genus '' Drosophila'' (in the family Drosophilidae), which is often called the "common fruit fly". Nearly 5,000 described species of tephritid fruit fly are categorized in almost 500 genera of the Tephritidae. Description, recategorization, and genetic analyses are constantly changing the taxonomy of this family. To distinguish them from the Drosophilidae, the Tephritidae are sometimes called peacock flies, in reference to their elaborate and colorful markings. The name comes from the Greek τεφρος, ''tephros'', meaning "ash grey". They are found in all the biogeographic realms. Description For terms see Morphology of Diptera anTephritidae glossary Tephritids are small to medium-sized (2.5–10 mm) flies that are often colourful, and usually with pictured wings, the subco ...

Agromyzidae
The Agromyzidae are a family of flies, commonly referred to as the leaf-miner flies for the feeding habits of their larvae, most of which are leaf miners on various plants. It includes roughly 2,500 species, they are small, some with wing length of 1 mm. The maximum size is 6.5 mm. Most species are in the range of 2 to 3 mm. General description Adult agromyzids can be recognized by the distinctive sclerotization of the head. The upper part of the frons, above the ptilinal suture (known as the frontal vitta) is lightly sclerotized and lacks setae, while the lower part of the frons and the dorsal area of the head tends to be much more heavily sclerotized and setaceous. Thus, the frontal vitta often forms a distinctive patch on the head, different in colour and texture from the rest of the head. The compound eyes are usually oval and fairly small, although in some species, they are larger and more circular. The wings are usually hyaline, although those of a few t ...

Scientists From Detroit
A scientist is a person who researches to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales ( 624–545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. History The roles of "scientists", and their predecessors before the emergence of modern scientific disciplines, have evolved considerably over time. Scientists of different eras (and before them, natural philosophers, mathematicians, natur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
