Aug 11, 2021 · Another way to distinguish these insects is by coloration. Water boatmen are typically dark brown in color, while backswimmers have a bolder patterning of black, yellow, brown, red, or white patches. Additionally, water boatmen have fine crosslines running across their backs, while backswimmers lack this feature.
This aquatic insect has breathing tubes near its abdomen that function as snorkels. These tubes reach up to the surface and capture oxygen, which the giant water bug stores in a bubble under its ...

Apr 16, 2024 · Water Boatmen and Humans. Water boatmen are unique bugs that play a special role in freshwater ecosystems. They are slender, oval, and streamlined, allowing them to swim efficiently with their long, oarlike hind legs. These insects are not harmful to humans and can even make for interesting sightings in your local pond or stream.
Dec 6, 2021 · Nutritional and Health Benefits of Edible Aquatic Insects. 3.1. Protein Content and Amino Acid Composition of Aquatic Insects. Aquatic insects have an average protein content of 59.55% (Table 2), and this value is higher than that of conventional animal meats [30, 31, 32].
- Mayfly Larvae. Mayflies begin their life cycles in water, where the mother lays her eggs on the surface and they either sink to the bottom or attach to some sort of relatively still surface, like a plant leaf, a log, or a rock.
- Dragonfly Larvae. Like mayflies (and any other species on this list that includes “larvae” in the title), dragonflies begin their lives directly in the water as eggs that then hatch into larvae and develop further into nymphs.
- Stonefly Larvae. Stoneflies are of the species that are intolerant of pollution, so having them in your pond is a good sign! In fact, they require between 8 and 10 parts per million (ppm) of dissolved oxygen.
- Water Strider. Water striders, often nicknamed “skater bugs” because of the way that they appear to skate atop the water’s surface, can be found all around the world.

Aquatic (Nepomorpha) and semi-aquatic (Gerromorpha) bugs are ubiquitous in freshwater biotopes, with some marine species too. They play an essential role in the functioning of aquatic ecosystems. Predators have strong top-down effects on food chains (Rumschlag et al., 2020) and connect aquatic and terrestrial ecosystems (Schriever & Lytle, 2020).
