Figure 2: Map of southern Indiana, U.S.A. showing results of surveys in area of predicted new range boundary. Stippled and diagonal-hatched areas are predicted range; stippled, 4,800 m from 16,384 ha forest; diagonal-hatch, 2,500 m from 1,024 ha forest that intersect cross-hatched area; circles, larval scars detected; triangles, larval scars not detected. Inset: study area within Indiana, USA.
