Arrowhead Blue  Glaucopsyche piasus

There are two known sites for Arrowhead Blue in Monterey County:  Chews Ridge (May 2016) and Cone Peak (May 2022).  

​

Our objectives for this seemingly rare species will be to survey the two known sites and search similar high elevation ridges and peaks in the Ventana Wilderness for new colonies.  The latter has become increasingly difficult, as recent fire and weather events have isolated remote areas from access, due to closed roads and trails.
