Longhorned Beetle
Monochamus scutellatus
"White-spotted Sawyer"


Monochamus scutellatus
I was about to step into my car on Guardsman Pass
when I looked down and saw this beast. Below is
another picture from 2003 showing the full length
of their
antennae.  Carol Davis 8-6-2019

This large White-spotted Sawyer came flying in like a bomber and
 landed on my car in Brighton, Utah. Larvae of these beetles feed on
dead or freshly cut conifers and the mature beetle feeds on bark
and needles of living conifers.  According to the Department of
Agriculture, wounds caused by the adult can introduce disease
which can eventually kill the trees.  Carol Davis
