When ready, they crawl out of the water to a safe place, shed their skin, and emerge as a young adult. I wonder if it is just because of the season, and if they will go away once it gets warmer. Red worms love the nutrient-rich conditions in a wastewater treatment plants and feed off the bacteria and sludge.

They are able to survive for weeks in a jar with no food or water. Female caddisflies lay masses of eggs on vegetation just above the water surface. Deer flies use the plants growing near the pond to rest on. In the next days or week, they complete their maturation. Other characteristics: Greenish or yellowish colour of spongillafly larvae matches with the sponge.

The larva attaches the case to some solid object, as like stone or a larger piece of submerged wood, and seals the opening. The adults are small flies and can be a nuisance, the compost-dwelling larvae can sometimes damage seedlings and cuttings.

Residents of Colcord, Okla., were shocked to discover tiny red worms in their drinking water this week. Dragonfly larvae have rectal gills and water is therefore pumped in and out of the rectum via the anus allowing gas exchange to take place. Larvae do not have eyes, and they are legless.

Depending on the fly, maggots can develop in water, wet soil, manure, rotting vegetable matter, decomposing animal tissue, and, in some cases, living animal and plant tissue, some are even predators. Oxygen concentration, associated with water velocity, is important to their larvae, as is the chemical content of the water. Drain flies (family Psychodidae) are very commonly mistaken for fruit flies. Identifying these larvae can be a fun activity for the whole family. The aquatic fly larvae will attract aquatic predators too such as water boatmen, which can fly to colonise new ponds, dragonfly larvae and the efts of newts. There are many species of fungus gnats, or sciarid flies, most of which are entirely harmless. Midges are often seen in large mating swarms over water.

Use an insect guide to compare your larvae to photos or illustrations in the guide. While destroying the breeding grounds will prevent the flies from laying more eggs, you'll still have to deal with adult drain flies … Greatly simplified, the life cycle is Egg (usually laid under water), Larva (free moving, water dwelling nymph) and Adult. Insects can be found in abundance around most any body of water. You might find them in areas like compost piles or broken drain pipes.

Here are a few ways to nip those little bloodsuckers in the bud. When they are fully grown, the larvae leave the water to pupate.
