Glaenocorisa propinqua
Glaenocorisa propinqua is a water boatman species (family Corixidae) found in lakes across Europe, Northern Asia (excluding China), and North America. Its abundance and distribution are strongly influenced by fish predation pressure, which primarily targets larvae. The species preys upon the water flea Holopedium gibberum, placing it as both predator and prey in lacustrine food webs.
