This summer we are experiencing something that we haven't seen much of in the past and that is Bluegrass Billbugs. You can see the damage in the sod behind the 16th green, which is exacerbated by foot traffic and drought stress. The insects likely came with the sod and that's why it is very defined and isn't more widespread. An insecticide has been applied to control the insect and this area is going to be resodded tomorrow. We've seen damage on #1, #4 and #16 but caught it early enough that the damage isn't noticeable, except for this location.
