Hemlock-Killing Insect Found In Ohio For 1st Time

State officials say a type of insect that kills hemlock trees has been found in an Ohio forest for the first time. The insects are called hemlock woolly adelgids. The Columbus Dispatch reports foresters found the insects in southern Meigs County in December, and they've been spotted on five trees. The bugs can kill hemlock trees within a few years by feeding on nutrients at the bottom of their needles. The Ohio Department of Natural Resources' forest-health supervisor says the bugs aren't very active in winter, giving officials some leeway to evaluate the size of the infestation and figure out how best to exterminate them. The newspaper says the insects have been found in 18 Eastern states and have been especially damaging in warmer, Southern states.
