The entomology division of UNL Extension has created an online resource featuring insect pests. The "Entomology Image Library" includes a wide variety of insects organized by pest categories and images to aid in identification.
The insect pest library is available by clicking "Entomology" at http://contentdm.unl.edu/cdm/collections.
The resource includes images to aid in identification. Each image is described by the subject’s taxonomic information.
The images on the website are available for use in publications. To request and image, send email to email@example.com.
