A Silver Lining for Rare Smith's Blue Butterflies

With a wingspan of only one inch, Smith's blue butterflies are a challenge to spot with the naked eye.

Despite their small size and rarity, the attractive bright blue coloring of the males and bright orange and brown coloring of the females never fails to catch the attention of U.S. Fish and Wildlife Service senior fish and wildlife biologist Jacob Martin.

Martin, based in Santa Cruz., is a native Californian and works to help recover threatened and endangered wildlife.  He has studied the butterfly for more than 10 years.

"Much of my work involves thinking and writing about how human activities affect the Smith's blue butterfly; it is always refreshing to get out and see them behaving naturally in relatively undisturbed habitat," Martin says.

Over the past two years, Dr. Richard Arnold of Entomological Consulting Services Ltd, has trained Martin and other U.S. Fish and Wildlife Service staff in techniques to survey for the Smith's blue butterfly. In addition to survey techniques, Arnold helped develop a protocol for long-term monitoring efforts at Salinas River National Wildlife Refuge, a safe haven for Smith's blue butterflies and many other native plants and animals that live within the coastal dune ecosystem.

With over 14,000 acres of habitat supporting hundreds of animal and plant species, there is no such thing as a "typical day" on Bitter Creek National Wildlife Refuge (Bitter Creek)—but some days stand out more than others.

That was certainly the case on September 30, 2016 when a giant kangaroo rat was discovered in the north-western portion of the refuge. "It's nice to get the documentation that it's on the refuge," said California State University (CSU), Stanislaus Research Technician Larry Saslaw.

He set the live trap that caught the giant kangaroo rat and thinks Bitter Creek can be the link connecting several neighboring areas that already serve as habitat to the species, thereby broadening its range.
