Glover's Silkmoth

wierd moth
My son works at a golf course in Sun Valley, Idaho, where he photographed this beautiful moth. What is it?
Signed, Fascinated by the lovely bug.

Hi Fascinated,
This is a Columbia Silkmoth or Glover’s Silkmoth, two subspecies of Hyalophora columbia. We are not skilled enough to tell which subspecies this really is.

The Hyalophora from Sun Valley, Idaho, is Glover’s, Hyalophora columbia gloveri … H. columbia columbia flies further north and east of both the moths depicted. There are state by state checklists on the WLSS. For $40.00 it is an amazing reference.

  1. I saw a Columbia Silk moth today at the Sawtooth National Recreation Area, during a time when we had 2nd grade elementary students up for a field trip. We were also doing a game regarding the migrating of Monarch Butterflies. This moth had perfect timing and was just sitting on the sidewalk for one of the activities. A chickadee even tried to eat it, then he/she flew away. I knew about sphinx moths, but had never seen this moth before. Beautiful and so large!
