I know it lays eggs on the Alfalfa plant but there is no alfalfa around here, to my knowledge. I have to illlustrate and teach about the life cycle of this butterfly and the red clover is much prettier to paint but I don't know if it is a host plant. Are there any good web sites that show the life cycles of butterflies, clearly, so the pictures can be used as reference for natural science illustration?

Many students of my country have always been of the opinion that the best brain behind the invention of technology is acquired from metaphysical practices and principles. And the metaphysical powers they acclaim have excluded the christian religous belief on the arts of science and technology. Moreso these lot always argue that one cannot rise to an envious point of technological perfection if one is not initiated into any occult where transcendental or rather supernatural knowledge is achieved by stanzas of ecantations and rituals.
Infact some of the students in question have concluded that a good christian cannot know much about the mystry behind the inventionof technology and pure scientific knowledge.

Essential elements used by plants in relatively large amounts for plant growth are called macronutrients. The major macronutrients are nitrogen (N), phosphorous (P), and potassium (K). Calcium (Ca), magnesium (Mg), and sulfur (S) are also macronutrients. All six nutrients are important constituents in soil that promote plant growth. Concentrations of these macronutrients in the soil are generally determined before the site is disturbed in order to complete a site reclamation plan. Knowing the initial macronutrient concentrations of the soil before disturbance can allow reclamationists to ensure that the same concentrations of macronutrients are in the soil after reclamation for revegetation purposes. When a site is revegetated, will fertilizer application be necessary? How much fertilizer will be necessary? Can the fertilizer simply be applied to the surface or will it need to be tilled into the soil? Which plants will grow in the area? These are some of the important questions that must be answered prior to mineland restortation. For more information on revegetation practices for reclamation, click here.

In addition to macronutrients, there are various trace elements that are necessary for plant growth. These trace elements are needed in smaller quantities than macronutrients. If the trace element is required for plant growth it is called a micronutrient. These include aluminum, arsenic, boron, cadmium, chlorine, copper, iron (sometimes thought of as a macronutrient), lead, manganese, sodium, zinc, and others. For more information on trace elements, see Munshower (1994).
