The pecan agroecosystem is one of the most important native tree crops in the United States. Many insects attack the trees, leaves, nuts, buds and are damaged by a wide variety of insects that lower the crop production. Natural enemies such as spiders may help to balance pest population densities in this agroecosystem, therefore they should be considered an integral part of pest management programs in Texas pecans. This website has been designed to help growers and biologists identify common spiders found in pecans and to help understand the role this eight legged group may play in biological control of pests in this crop.

Collections were made in several pecan orchards over a period of three years in Texas, mainly at Robertson Co and Comanche Co. Specimens were collected by using different sampling techniques.

This partial list has been generated based on collections made on several orchards throughout Texas. It contains 193 species in 28 families putting this agroecoystem as one of the richest on spider fauna. Specimens are deposited in the Entomology spider collection at Texas A&M University.
