Breeding rare butterflies

A trail of 4 pages, marked with comments, by sweetpea
About this trail:
In a double-wide trailer in Los Angeles' San Pedro area, Johnson is presiding over the rebirth of the Palos Verdes blue, one of the rarest butterflies in America. As manager of a pioneering program to breed the butterfly in captivity, she has witnessed hundreds of moments like this one: butterfly after butterfly crawling out of its pod, or pupa casing, lured by the spring warmth and light. Johnson, 37, never tires of the drama. Each "pop" means that the Palos Verdes blue is one butterfly further from extinction.

Unimproved grassland containing native grasses and wild flowers is a major habitat for butterflies and can support more than half of 60 native species, including several rare and declining species. Almost any patch of tall grassland containing native species can be breeding habitat for some butterflies.

It seems like a perilous place for a rare butterfly to call home. Just out of sight of its forest sanctuary, mammoth steam shovels are devouring a mountain that had the bad luck to be made mostly of iron, as many do near Belo Horizonte, capital of Brazil’s state of Minas Gerais. Meanwhile, urban refugees are turning this little valley community from butterfly habitat into a landscape of vacation homes and condos.
