The Indiana state entomologist says now's a good time for land owners to examine their ash trees for the tell-tale D-shaped exit holes left by the emerald ash borer.
Entomologist Phil Marshall says emerald ash borer adults have been spotted in the Brownsburg area of Hendricks County, which means they may be spotted in other counties in central and southern Indiana.
He says it may be a little later before adult ash borers north of the Wabash River take flight.
Hendricks is one of 84 Indiana counties quarantined for the ash borer.
The quarantine restricts movement outside the quarantined area of regulated ash materials, including whole ash trees, limbs and branches.
The metallic-green beetle that's native to Asia has decimated ash trees in several states since 2002.
