Mesovelia are most likely to be found amongst the marginal vegetation of ponds, wetlands, or slow flowing streams and rivers. They are rarely found in abundance, unlike Microvelia which are often found in high abundance.
They are predators, feeding on aquatic and non-aquatic invertebrates trapped on the water surface.
Mesoveliids are only likely to be found amongst marginal vegetation above the water surface, and they may have limited value as water quality indicators. They have not been assigned any tolerance values.
