What do diving beetles do?
They are scavengers, and love earthworms, small pieces of meat, and dead insects. Sometimes they can catch a snail or another living aquatic creature. They are not very good at catching fish, but may succeed at night, so we do not recommend keeping beetles and fish in the same tank.
How long do diving beetles live?
The giant diving beetle (Cybister fimbriolatus) is 2.6–3.3 cm long, and is widespread throughout the United States, mostly in warmer climates. It can be collected in small water bodies without fish, including roadside puddles and cattle tanks. Each beetle can live for several years.
Where do diving beetles come from?
Predaceous diving beetles are in the Family Dytiscidae (from the Greek for “able to dive”); with 4300 species worldwide (about 500 in North America), they are the largest family of aquatic beetles. Typically, they live in the shallow, still waters of lakes and ponds or in the pool areas of streams.
How big is a diving beetle?
Diving beetles are oval and flat and range in length from 1.5 mm to more than 35 mm (0.06 to more than 1.4 inches). They are well adapted to an aquatic environment. The hind pair of legs is long, flattened, and fringed to provide surface area that aids in flotation and swimming.
Can diving beetles fly?
Habitat and Conservation Because predaceous diving beetles are strong fliers, they can fly away to new water if the pond they are in dries up, or if electric lights lure them away from “home.” This is why water beetles are sometimes found in birdbaths and swimming pools.
Can diving beetle swim?
Predacious diving beetles are excellent swimmers. They have a very smooth and streamlined exoskeleton. Their hind legs are covered with long hairs called natatory setae. They use these hairs like people use flippers, and they use them very well.
How many legs do diving beetles have?
Six legs
Larvae and development Six legs protrude from along the thorax, which also sports the same thin hairs. The head is flat and square, with a pair of long, large pincers.
Why do diving beetles dive?
Harnessing it, some aquatic beetles carry the oxygen they need underwater in the form of a temporary bubble, sort of like a natural scuba tank. Others encase themselves in a layer of air and draw oxygen from it their whole lives. Predaceous diving beetles are an aquatic insect family common in lakes, ponds and streams.
Does a diving beetle have a backbone?
Insects do not have a backbone or internal skeleton. Instead, they have an exoskeleton which is a hard outer covering that protects their body.
