Ecology
editThe species emerge in midsummer to mate and lay eggs. After they lay their eggs they die, living their young to feed on such plants as Utricularia minor and other Utricularia species. They feed on them till adulthood, and then go to overwinter. They grow up to 1.5–2 millimetres (0.059–0.079 in) long, with females being the largest.[1]
Habitat
editThey overwinter in Sphagnum moss, which can be found wet boggy areas.[1]
Behavior
editThis type of species can swim, which is rarity for its kind. When the moss goes underwater they use their front legs for breaststroke like movements to stay afloat. However, they cannot do this when they are underwater.[1]
