Samples of Hemiptera were collected at sixteen naturally vegetated derelict sites using both suction apparatus and beating bags Sample sites were chosen to provide a broad range of vegetation types, representing changes in successional stage and soil pH Hemipteran diversity indices were significantly correlated with site area, but not with soil pH or site age Vegetation species diversity and evenness indices were not significantly correlated with site age, area or soil pH Hemipteran and vegetation evenness (using both Shannon evenness, J, and Heip's evenness, F 10 ) were significantly correlated Similar evenness correlations were found when sub‐order Homoptera and vegetation were compared No significant correlations were found between the diversities of sub‐order Heteroptera and vegetation Factors determining Hemiptera and vegetation diversity on these sites are discussed It is suggested that rare plant species are of importance in determining the presence of rare species of Hemiptera on the sites It is proposed that diversity as a concept is of most value in ecological studies when its two components, species richness and evenness are considered separately
