Infestation expansion 1986-87 map
from Chapter II of Spatial Analysis of Ecological Factors Related to Grasshopper Population Dynamics in Wyoming
Fig. 17. Spatial distribution of rangeland grasshopper outbreaks during 1986-1987, when the infestation area increased by at least 243.6% over the previous year (dark shading = uninfested area; yellow = area infested in 1986 only; blue = area infested in 1987 only; green = area infested both years; black = state and county borders).
