The primary aim was the identification and determination of distribution patterns of the cicadas in relation to the plant distribution in a UNESCO Biosphere Reserve, located in extreme southwestern Texas, USA. Cicadas were collected in all areas of the reserve, which is also designated as a US National Park, noting specific location, habitat characteristics and plant species present. The distribution of each species was mapped and correlated to vegetation type in those locations. There are twelve species (all native) in six genera of cicadas found within the reserve. Tibicen chisosensis Davis is the only endemic species but Diceroprocta canescens Davis and Okangodes terlingua Davis have very limited distributions outside the official reserve boundaries. Each species shows a close association to particular vegetation types. The distribution of particular cicada species is restricted by the distribution of their host plants. By the end of the study we were able to predict which species would be found in particular habitats [Acta Zoologica Sinica 53(3):454 –462, 2007].
