We estimated and described the arthropod fauna on purple loosestrife (Lythrum salicaria) plants in northeastern Illinois wetlands. A total of 1063 individual arthropods were collected—930 insects and 133 arachnids. The av- erage number of arthropods ranged from 19.00 to 86.75 individuals per loos- estrife plants of a single root crown. We collected individuals from twenty-five families representing 8 orders of insects. Miridae, Anthocoridae, Lygaeidae, Cicadellidae, and Aphididae were each represented by at least 50 individuals. Three orders and ten families were found that had not been previously reported as occurring on purple loosestrife, but many of these taxa were represented by only a few individuals.
