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.
While some insects, like moths, spin a cocoon, a butterfly uses a chrysalis, which is essentially hardened skin. Different species of butterflies stay in the chrysalis, or pupal stage, for different periods of time. This can range from about seven days to more than a year, but for a large number of species it is less than 30 days. The well-known monarch butterfly, for example, spends between nine and 14 days in a chrysalis, while the painted lady butterfly spends only seven to 10 days in the chrysalis.
The process from egg to butterfly is weather dependent and also depends on the regional climate. It can take about four weeks in the peak of the summer in warmer climates. The egg takes 5 to 10 days, the larva/caterpillar and pupa/chrysalis each take about 10 to 14 days. In winter, autumn and spring it takes a lot longer (if it happens at all â they continue to breed in Northland).
