Silvery blues are the closest living relatives to the extinct Xerces blue (Glaucopsyche xerces). Since 2024, scientists have relocated dozens of these “ecological stand-ins” to the Presidio’s sand dunes, where the insects now serve as pollinators and critical members of the food web.

The baby blues are back & better than ever!

This month, Academy scientists, partners, and volunteers released dozens of silvery blue butterflies (Glaucopsyche lygdamus) in the Presidio, as part of ongoing efforts to restore ecosystem function & support butterfly populations in the Bay Area.
