Hello,

I work for NRCS on the eastern plains of Colorado and customers are asking about this moth.  There is an abundance of this type a moth this fall (see pic).  It is medium size about 3.5 inches wide.  This particular picture shows the moth without its body, which is black with a rusty tail (like the head).  That is what I noticed as it is flying around.  There are hundreds of these moths, which are quite beautiful, but some people show a concern that it might be damaging the cottonwood trees. Thank you.
