This family can be found in a large area of North America. This species can range from eastern Alaska down to Utah and east to the Great Lakes states. Because of their reproductive needs, these organisms live near shallow, slow moving bodies of water such as ponds, lakes, streams, bogs, marshes. These bodies of water are also inhabited by other creatures such as snails, other insects or frogs. The adults perch on herbaceous plants, shrubs and tree bark near the water source. The larvae live immersed in the water source.
