Based on observations from specimens collected in Idaho, the adult trophic status of the giant lacewing Polystoechotes punctatus (F.) is confirmed to be carnivorous. The male reproductive organs are described and compared to published descriptions of other neuropterans, showing few dissimilarities, except in number and placement of accessory glands and the reflexed nature of the first accessory gland in P. punctatus. The collection of associated mites is reported for the first time.
