A Chronology of the Disappearing Miami Blue (MB)
Thousands or millions of years ago.
The MB appeared as a new species.
1970s and before.
Thousands or millions of MBs lived in Florida.
I collected two MBs on Big Pine Key, along a roadside, as part of making an insect survey.
1970s – 2000s.
Habitat changes and pesticides reduced the numbers of MBs.
Hurricane Andrew greatly reduced the population size of the MB.
Researchers found one remaining population of this species of about 50 individuals.
Researchers found only a few MB individuals.
Habitat change, pesticide spraying, and other factors could easily make the MB go extinct.
