Notonectidae is a cosmopolitan family of aquatic insects in the order Hemiptera, commonly called backswimmers because they swim "upside down" (inverted). They are all predators and typically range from 0.5 to 1.5 cm (0.2–0.6 in) in length. [1]
The petroleum fly, Helaeomyia petrolei (synonym Diasemocera petrolei [2]), is a species of fly from California, USA. [3] The larvae feed on dead insects and other arthropods that become trapped in naturally occurring petroleum pools, making this the only known insect species that develops in crude oil, a substance which is normally highly toxic to insects.
Ephydridae (shore fly, sometimes brine fly) is a family of insects in the order Diptera. Shore flies are tiny flies that can be found near seashores or at smaller inland waters, such as ponds. About 2,000 species have been described worldwide, [ 2 ] including Ochthera .
The nymphs of the hemimetabolous orders mayflies, dragonflies and stoneflies, and the larvae of the holometabolous orders megalopterans and caddisflies, possess tracheal gills, which are outgrowths of the body wall containing a dense network of tracheae covered by a thin cuticle through which oxygen in the water can diffuse.

The larvae develop within 38 to 65 days, [17] which allows this migrant dragonfly to reproduce in temporary waters or even in swimming pools. [18] However, the larvae seem to be very sensitive to temperature. [19] The life expectancy is not known and because of their high mobility it is almost impossible to determine.
The larvae of dobsonflies live along the rocky bottoms of streams. Chiefly active during the night , they ambush prey in the middle of riffles which supply plenty of oxygen and stir up prey. [ 12 ] They are generalist predators; dissections have revealed that they primarily eat aquatic immatures of mayflies , caddisflies , stoneflies , and ...
Blackfly Larvae from United Arab Emirates. Simulium is a genus of black flies, which may transmit diseases such as onchocerciasis (river blindness). It is a large genus with almost 2,000 species and 38 subgenera. [1] The flies are pool feeders.
The larvae of the green bottle fly (Lucilia fly) are now used exclusively for this purpose, since they preferentially devour only necrotic tissue, leaving healthy tissue intact. This is an important distinction, as most other major varieties of myiasitic fly larvae attack both live and dead wound tissue indiscriminately, effectively negating ...
