Aquatic Neuroptera (Sisyridae - Spongillaflies) of Michigan

Introduction

Although Neuroptera is a sizable insect order of about 5000 species, only two families - Nevrorthidae (considered a "basal" family of Neuroptera (Aspöck et al. 2001)) and Sisyridae - have become adapted to an aquatic life phase. Only Sisyridae is found in the Nearctic, and in our area. There are 3 species in 2 genera recorded in Michigan.

Adults lay eggs on vegetation overlying an aquatic body containing freshwater sponges, upon which spongillafly larvae feed by using long stylet mouthparts to pierce and suck out contents. Like Megaloptera, larvae crawl out of the waterbody to create a pupal chamber, and after about 1-2 weeks the adult uses special mouthparts to emerge. Adults usually live about several weeks.
