The oil and gas industry is an exception, with businesses predicting an average raise of 4% this year. At the bottom end of the spectrum are hospital workers, who typically were expected to bring home just 2% more in 2015 than they did in 2014.
Butterflies and moths have four stages of life: egg, larva (the caterpillar stage), pupa (the chrysalis phase in a butterfly's development), and adult. It takes a monarch butterfly just 28 to 38 days to complete its life cycle, with warmer temperatures generally being responsible for faster development.
This process of complete transformation is known as holometabolism. The amount of time required to transform completely varies from one species to another, but in general it takes about two weeks. For species that survive the winter by staying in the chrysalis, it can take months.
