Illinois agriculture officials remain very concerned over a destructive insect making its way across the state.  The Emerald Ash Borer is already responsible for millions of dead trees in northern Illinois.  The bug's larvae actually embeds itself underneath tree bark, ending its ability to transport water and nutrients.  It is highly attracted to ash trees which are found all over Illinois.  

In southern Illinois, officials worry the insect has potential for infestation in Effingham and Marion counties.
