Johnson’s Hairstreak (Callophrys johnsoni) This butterflies’ larva feed on mistletoe, specifically that of the Western hemlock situated at low elevation. Living next to the ocean and having a hemlock heavily infested with mistletoe just up the street helped determine the species is C. johnsoni and not the very similar C. spinetorum.

  1. Cool find, Gary! I find hairstreaks some of the most beautiful families of butterflies. Posted 7 years ago
    1. Thank you, Ferdy. They are new to me. I am still wondering how this group of butterflies got the name, “hairstreaks”? Posted 7 years ago
      1. It's because of the little hairlike projections that you can see on the hindwing. Strangely not all hairstreaks have the hairs.... Posted 7 years ago, modified 7 years ago
      2. "Hairstreak" refers to the hairs (and sometimes spectacular appendages) at the end of their wings, which is often used to mislead predators into thinking their head is there. Yours has it too! Posted 7 years ago
  2. To Ferdy and “morpheme”, many thanks for the clarification. Yes, I did see those little appendages sneaking out the back of the wings but never thought of calling them “hairstreaks”. Now I know. Posted 7 years ago
