It is sometimes a minor pest of cotton, feeding mostly on young shoots, piercing the stems and sucking the sugar-rich juices intended for shoot growth. It has been known to cause the introduction of a fungus, which rots the cotton boll. Nymphs feed on seeds in very small bolls or in opening bolls.
The boll weevil (Anthonomus grandis) is a beetle which feeds on cotton buds and flowers. Thought to be native to Central Mexico,[1] it migrated into the United States from Mexico in the late 19th century and had infested all U.S. cotton-growing areas by the 1920s, devastating the industry and the people working in the American South. During the late 20th century, it became a serious pest in South America as well. Since 1978, the Boll Weevil Eradication Program in the U.S. allowed full-scale cultivation to resume in many regions.
Adult weevils overwinter in well-drained areas in or near cotton fields,and farms after diapause. They emerge and enter cotton fields from early spring through midsummer, with peak emergence in late spring, and feed on immature cotton bolls.
The boll weevil lays its eggs inside buds and ripening bolls (fruits) of the cotton plants. The female can lay up to 200 eggs over a 10- to 12-day period. The oviposition leaves wounds on the exterior of the flower bud. The eggs hatch in 3 to 5 days within the cotton squares (larger buds before flowering), feed for 8 to 10 days, and finally pupate. The pupal stage lasts another 5 to 7 days. The lifecycle from egg to adult spans about three weeks during the summer. Under optimal conditions, 8 to 10 generations per season may occur.

Sincerely Lauralit1,
After the federal government was established in Washington D.C, the court was placed in the United States Capitol, in a small place in the basement. As the senate expanded and progressively occupied more spaces, the court had to move from one room to another within the capitol on two occasions: first in 1810, to the chamber that left the senate, a space that had to share "with other courts, like the Circuit Court of the United States, and the Orphans Court of the district of Columbia". And again in 1860, when It moved to the today called "Old senate chamber", where it remained until its current location.
The supreme court remained in the capitol until 1935, except for the period 1812-1817, during which it temporarily left the city of Washington D.C, as a result of the Anglo-american war of 1812. In 1929, the presiding judge, William Howard Taft, got a proper building for the court, with the purpose of distancing itself from congress, as an independent branch of the government, which began to occupy in 1935.

<span>The Earth was
formed 4.6 billion years ago from mixes of hot gases and solids. During those
days Earth almost had no atmosphere and its surface was molten. Through time
the Earth cooled and the atmosphere formed consisting mainly of gases that
spewed from volcanoes. The atmosphere was extremely hot, composed of hydrogen,
sulfide, methane, and carbon dioxide that is 200 times more potent compared to
today’s atmosphere. Half a billion years later, Earth started to cool and
solidify its surface making it conducive for water collection and making life officially
inhabit the planet.</span>
