Silver-Spotted Skipper (Epargyreus clarus)

The silver-spotted skipper, Epargyreus clarus, frequents roadsides, fields, and backyard gardens throughout North America. Skippers dash quickly from flower to flower, as if they are skipping around the meadow. What Do Silver-Spotted Skippers Look Like? Chances are youve seen a silver-spotted skipper. With their brown wings and quick movement, they might not be the first butterflies youd stop to observe. Take a closer look, and youll notice bands of orange on the forewings, and a silvery patch in the center of the hindwings. The silver-spotted skipper is the largest skipper in North America, with a wingspan of 1 3/4 - 2 5/8 inches. Silver-spotted skippers have enormous eyes that appear to bulge out from the head. Epargyreus clarus also has short antennae with clubbed ends. The odd-looking caterpillar has an enlarged head capsule and a pronounced neck collar. With a deep rust or black head and two bright red eyespots in the front, the caterpillar appears quite like a cartoon alien from outer space. The larvas body is yellow-green, with thin dark lines running across its width. By some accounts, the silver-spotted skipper lays her eggs on plants near the host plant, but not on the actual host. This requires the newly hatched larva to crawl and locate its food source. Most experts seem to dispute this theory, and argue the butterfly lays directly on the host plant. How Are Silver-Spotted Skippers Classified? Kingdom - AnimaliaPhylum - ArthropodaClass - InsectaOrder - LepidopteraFamily - HesperiidaeGenus - EpargyreusSpecies - Epagyreus clarus What Do Silver-Spotted Skippers Eat? Larvae feed on legumes, especially woody legumes. Black locust is the favorite host plant. Other host plants include honey locust, false indigo, bush clover, and tick-trefoils. Adult silver-spotted skippers nectar on many flowers, but show a clear preference for blue, red, pink, or purple varieties. They rarely visit yellow flowers. The Silver-Spotted SkippersLife Cycle Like all butterflies, the silver-spotted skipper undergoes four stages during its life cycle, a complete metamorphosis. The generations per year vary by region, with southern populations having the most broods. Egg - Green, dome-shaped eggs are laid singly on upper side of leaves.Larva - The caterpillar has a large brown head, with red eyespots at the front. The body is a yellow-green color.Pupa - These skippers overwinter in the chrysalis, hidden in rolled leaf litter.Adult - Adults emerge in spring. Males perch on tall weeds or branches, watching for females. They also patrol for potential mates. Special Adaptations and Defenses ofSilver-Spotted Skippers At night, or when the daytime weather prohibits flight, silver-spotted skippers hang upside down under leaves. Caterpillars build themselves tiny shelters using carefully cut pieces of leaves. As they grow, they abandon their old homes and build larger ones by joining leaves with silk. Where DoSilver-Spotted Skippers Live? Open parks, fields, gardens, and meadows, and where larval food plants are available. In North America, the silver-spotted skipper is common from Mexico to southern Canada, with the exception of the Great Basin region and western Texas. Worldwide reports include sightings in parts of Europe, Asia, and Australia.

Essay on Treatment Using Stem Cells - 655 Words

Stem cells are undifferentiated cells, or cells that can differentiate into different cells. Stem cells are often divided into two different classes: embryonic and adult. Adult stem cells can turn into many, but not all, cells, allowing these cells to be used in the treatment of some problems. Because of this, adult stem cells are often considered â€Å"multipotent†. Embryonic stem cells can become any type of cell and any organ, creating great optimism in medical fields. Because of this, embryonic stem cells are often considered â€Å" pluripotent†. Although there are great developments that can come out of stem cell research, there exist many problems that concern many, but not necessarily most, people. These include the classic arguments†¦show more content†¦Because of this, the first idea that comes up in order to increase donations is to provide some sort of compensation for the donations. Although compensation could be good and might increase the amount o f donations, compensations can act as a reason to cause people who would otherwise not donate to donate, a situation that can and will upset many people. Because of this, federal guidelines have been put in place in order to prevent this from occurring. Because of this, it is necessary that investors freely invest their resources and, in some cases, do not expect for any sort of compensation while understanding the risks. Because this is the case in the United States, there are no problems for investors in the United States. For the scientists, there are fewer problems. As long as the scientists are freely doing their research, there are no problems for the scientists. If the scientists like their research, then there are no problems for the scientists. As long as scientists freely conduct their research, then there are not problems for the scientists. Because this is the case in the United States, there are no problems for the scientists in the United States. Finally, there are the issues concerning the embryos. As previously stated, whether or not an embryo can be considered â€Å"human† is a classic argument. Although there are many valid arguments on both sides, the argument is focused on and designed for abortion.

Angina Pectoris Care Plan free essay sample

Care Plan For Angina Pectoris Angina Pectoris Chief Complaint: Patient complains of having tightness and pain in his chest that seems to move down the left arm. Patient describes the pain as being sharp and can be sometimes a mild pain or an immobilizing pain. Medical Diagnosis: Coronary Artery Disease Pathophysiology of: Angina Pectoris Angina Pectoris develops when coronary blood flow becomes inadequate to meet myocardial oxygen demand. This causes myocardial cells to switch from aerobic to anaerobic metabolism, with a progressive impairment of metabolic, mechanical, and electrical functions. Angina pectoris is the most common clinical manifestation of myocardial ischemia. It is caused by chemical and mechanical stimulation of sensory afferent nerve endings in the coronary vessels and myocardium. These nerve fibers extend from the first to fourth thoracic spinal nerves, ascending via the spinal cord to the thalamus, and from there to the cerebral cortex. (http:// emedicine. medscape. com/article/15021 5-overview, 6/1 5/10 12:30 pm) Medical Interventions: Diagnostic Tests: 1. Coronary intravascular ultrasonography A coronary intravascular ultasonography is an invasive ultrasound performed rom a transducer within the lumen of the coronary arteries. (Laboratory test and diagnostic procedures, By: Cynthia Chernicky, 5th Edition 2008). Electrocardiography is a noninvasive acoustic imaging procedure that determines the size, shape, position, thickness and movements of the heart valves, walls, and chambers during each cardiac cycle.

Route and Dosage: Adults: PO 1 mg. tablet every 5 hours while awake. (Buccal) 0. 1 To 0. 8 mg. hr. worn 12 to 14 hours at a time. (Transdermal Patch) Adverse Reactions: Some side effects of this drug that should be reported to a healthcare provider if they become severe are as follows: headaches dizziness flushing lightheadedness reported to a healthcare provider immediately. The adverse effects of nitroglycerin are: Nausea vomiting Weakness blurred vision fainting spell abdominal pain sweating chest pain pale skin rashes Ђ peeling of the skin blisters on the skin hives itching difficulty breathing Surgery: 1 Transluminal coronary angioplasty Your hearts arteries can become clogged from a buildup of cholesterol, cells or other substances. This can reduce blood flow to your heart and cause chest discomfort. Sometimes a blood clot can suddenly form or get worse and completely block blood flow, leading to a heart attack. Angioplasty opens blocked arteries and restores normal blood flow to your heart muscle. Angioplasty, a type of percutaneous coronary intervention (PCI), is not major surgery. It is done through a small puncture in a leg or arm artery and opens a clogged heart artery by inflating a tiny balloon in it. Assessment: Subjective: Patient is a 68 year old male with a history of coronary artery disease, and hypertension. Vital Signs as follows: -r: 986 R: 25 p: 102 Objective: Patient seemed to be crying and in severe pain. Skin was flushed, and clammy.

Contrast DOS to Unix essays

Contrast DOS to Unix essays Compare and Contrast Microsoft DOS with UNIX As is suggestive of its name, an operating system OS is a collection of programs that operate the personal computer (PC). Its primary purpose is to support programs that actually do the work one is interested in, and to allow competing programs to share the resources of the computer. However, the OS also controls the inner workings of the computer, acting as a traffic manager which controls the flow of data through the system and initiates the starting and stopping processes, and as a means through which software can access the hardware and system software. In addition, it provides routines for device control, provides for the management, scheduling and interaction of tasks, and maintains system integrity. It also provides a facility called the user interface which issues commands to the system software. Utilities are provided for managing files and documents created by users, development of programs and software, communicating between users with other computer systems and managing user requirements for programs, storage space and priority. There are a number of different types of operating systems with varying degrees of complexity. A system such as DOS can be relatively simple and minimalistic, while others, like UNIX, can be somewhat more complicated. Some systems run only a single process at a time (DOS), while other systems run multiple processes at once (UNIX). In reality, it is not possible for a single processor to run multiple processes simultaneously. The processor of the computer runs one process for a short period of time, then is switched to the next process and so on. As the processor executes millions of instructions per second, this gives the appearance of many processes running at once. User programs are usually stored on a hard disk and need to be loaded into memory before being executed. This presents the need for memory management, as the m...

A sound knowledge of social policy is essential for effective social Essay

A sound knowledge of social policy is essential for effective social work practice - Essay Example Implementing social policy consists of using the rules and regulations of governments to directly impact the welfare of citizens by providing them with income or services such as social insurance, public assistance, healthcare, welfare services and adequate housing (Marshall, 1965). This paper proposes to evaluate the importance of social policy for effective social work practice. The relationship between social policy and social work, the influences of political processes, the application of social policy and theory to a range of current social issues and problems especially related to social inclusion and welfare rights will be identified. The concept of the government taking responsibility for the citizens’ problems has a long history, though the term welfare state has come into use only since 1941. In Britain in 1942, William Beveridge published Social Insurance and Allied Services commonly known as the Beveridge Report. This seminal document was crucial in turning Great Britain into a welfare state (Macarov, 1995). Labour elected in July 1945 established a new welfare system by implementing the main proposals of William Beveridge’s path-breaking report. Labour replaced the multitude of schemes for the unemployed, the old and the sick with a single unified scheme which essentially remains to this day. Other than for pensions, the Act was less generous than what had been advocated by Beveridge. The low levels of benefit caused many people to rely on National Assistance â€Å"because retirement, unemployment and insurance benefits were pitched too low and did not provide separately for housing costs† (Brivati & Bale, 1997). The new National Health Service (NHS) which gave the medical profession representation and control over spending resulted in spiralling costs in the late 1940s. Comparatively, education policy as the 1944
