 Climate Change Of Monarch Butterfly [Nicole Smith]   Climate variations during the fall and summer affect butterfly reproduction. Rainfall and freezing temperatures affect milkweed growth. Omar Vidal, director general of WWF-Mexico, said, "The monarch's lifecycle depends on the climatic conditions in the places where they breed. Eggs, larvae, and pupae develop more quickly in milder conditions. Temperatures above 35   °C (95   °F) can be lethal for larvae, and eggs dry out in hot, arid conditions, causing a drastic decrease in hatch rate." [174]  If a monarch's body temperatures is below 30   °C (86   °F), a monarch cannot fly. To warm up, they sit in the sun or rapidly shiver their wings to warm themselves. [175] Climate change  may dramatically affect the monarch migration. A study from 2015 examined the impact of warming temperatures on the breeding range of the monarch, and showed that in the next 50 years the monarch host plant will expand its range further north
