The Bay checkerspot butterflies are back at Edgewood County Park and Natural Preserve this year. This insect species, included on the federal endangered species list, is found on the Peninsula nowhere else but at Edgewood.
A scientific restoration program has been underway since 2007 to bring the population back to a self-sustaining level.
The severe drought conditions this year threatened to cancel any efforts to bring additional caterpillars to Edgewood from their home south of San Jose, where there is a large and stable population. However, conditions suddenly changed and caterpillars were recently translocated. That means if the weather continues to cooperate, they should pupate into lovely butterflies and take flight.
On March 29, chief scientist Dr. Stuart Weiss will lead a lucky few individuals on a walk through the restricted butterfly habitat at Edgewood. This is a special opportunity to see this rare and beautiful insect, and learn about its plight and future from the man who is leading the efforts to save it from local extinction.
The three-hour walk starts at 1 p.m. Saturday, March 29, in Redwood City. Space is limited, and you must pre-register to attend.
