The picture shows what is one of the commonest water beetles the Common Black Diving Beetle, Agabus bipustulatus, which is about 1 cm long. They’re not particularly sensitive to pollution: some can live in the most apparently inhospitable ponds including those with lots of bare polluted sediments and with no water plants. But this is such a diverse group of animals that you can find just about every possible different way of living amongst them: from docile grazers to fierce predators.

So take a closer look at pretty yellow and black stripy hoverflies as they dash over the pond and the delicate little non-biting midges with their feathery antennae that are some of the earliest colonists and the beautiful transparent larvae of the phantom cranefly. this is super weird but my wife and i were curious as to whether anyone had tried to stick their dick in those wiggly water tubes (you know the ones) and how it felt. Many look a bit like the larvae of alderflies but often have two tails, and they lack the gills along the side of the body that are one of the distinguishing features of alderfly larvae.There’s nothing to really worry about if you don’t have them, and no special need to introduce them. Lesser water boatmen swim on their fronts, and greater water boatmen – backswimmers – swim on their backs. Added to this the tiny Lesser Backswimmer Plea leachii is smaller than virtually all other ‘lesser’ water boatmen. But get around they do, although they will probably take quite a few years to arrive naturally in a new garden pond.

Water beetles are one of the most diverse groups in freshwater – in Britain there are around 350 species – but because they are the Little Brown Jobs of the freshwater world many people don’t realise quite how many different types there are.

So it might come as a bit of a shock to realise that there are more different kinds of these creatures living in freshwater – especially the flies – than any other kind of animal. For those interested in developing their wildlife identification skills, Lesser Water Boatmen are good place to start – once you get your microscope or hand lens eye in they have some nice easy characters to distinguish them.

It’s the common water slater that usually is found in garden ponds: we’ve never seen the one-spotted water slater in a garden pond, though given how little we know about garden ponds it wouldn’t be surprising to see it turn up. They don’t care for acid water though, so you don’t find them in more mountainous uplands, nor usually in the acid heathland ponds of southern England. There are only two likely to seen in Britain, and by looking closely at them you can actually tell them apart quite easily: the common water slater ( Asellus aquaticus) has two white spots on its head, whereas the more uncommon, slightly classier, one-spotted water slater ( Asellus meridianus) has only one spot on its head. It is not difficult to attract Lesser Water boatmen and backswimmers to garden ponds: both the species of alkaline, base-rich water will turn up quickly.

This is because they naturally live in places where oxygen levels can be low – but there’s nothing unnatural about that in ponds, and in clean rivers they like the naturally silty places. Flies and worms also get a bit of a bad reputation because as well as always being present in the nice ponds they can live in some pretty horrible looking places too. Although approximately half of the species of water bug recorded from ponds are different kinds of Lesser Water Boatmen, their sheer variety is sometimes not appreciated because they do all look quite similar. Water bugs aren’t just pond animals – rivers and streams may have backswimmers in the stiller, well-vegetated areas, and saucer bugs, water scorpions and occasionally water stick insects too.

The reason for their polluted water reputation is that in the early days of river pollution studies they were one of the survivors when sewage was discharged pretty much untreated into rivers. Its telescopic snorkel tail is a great way of getting oxygen amongst rotting vegetation that is naturally lacking in this essential gas.Reddit and its partners use cookies and similar technologies to provide you with a better experience. Water slaters have to get around from pond to pond by being moved on plants, or by birds, or floods. The backswimmers comprise two families in Britain, the Notonectidae and, for the Lesser Backswimmers, the Pleidae.
