Dytiscus marginalis larvae

Both the larvae and the adults are voracious predators, feeding on a wide range of aquatic life including newts and fish etc. and will also consume carrion, the young larvae are also cannibalistic at high densities. The adults will exude a foul smelling liquid from the abdomen when alarmed or threatened and this will generally deter predators Dytiscus marginalis larva, last instar The full grown larva is fat and heavy, it doesn't hang at the surface anymore, but chooses shallow water where it still can get it's tail tip in contact with the air Predatory as adults and larvae, eating anything they can tackle, including other water insects, tadpoles and even very small fish. The larvae are yellowish brown in colour, growing to about five centimetres in length, and possess a fierce pair of jaws - handle with care! They need damp soil by the edge of the water in order to pupate successfully cannibalistic and will eat other Great Diving Beetle larvae. Large larvae in the final stage before pupation, are of sufficient size to even catch and eat small fish. The larvae often appear scorpion-like in the water because they move about with their tails extended vertically upwards. They will frequently push the tail u The carnivorous larvae of Dytiscus species prey on other animals, e.g., insect larvae, amphibian larvae, isopods, or fish fry (Blunck 1923; Balduf 1935; Wesenberg-Lund 1943; Jeffries 1988; Johansson and Nilsson 1992). They first inject digestive enzymes through the mandibles into the body of the prey then suck the dissolved body fluids

The young larvae grow rapidly, and by late summer they are ready to pupate; before doing so they leave the water and burrow in wet marginal soil. The young adult beetles emerge from their pupae (they 'eclode') typically in mid autumn, but they remain buried in the wet soil through the cold winter months, returning to the water as the days lengthen and get warmer The 14 species of Dytiscinae, typified by the great diving beetle Dytiscus marginalis L. are some of the most familiar British beetles, often pictured in general guides, but there are six similar species and so species-level ID is harder than may be first thought. Females often have grooved (sulcate) elytra, while males have circular sucker pads on the fore tarsi for mating purposes Thus, a Dytiscus trunk is very similar to a small-span wing profile and should therefore create a certain dynamic lift during fast swimming.

Their larvae crawl on land at the end of instar III to pupate in a shallow burrow near the water. Two to three weeks later it emerges as an adult. The development of D. latissimus and D. lapponicus larvae was closely followed in the laboratory. All eggs, larvae, pupae and adults were monitored daily and the date of hatching, moulting, pupation and death was recorded and used to calculate developmental time of the.
