* Most aquatic insects go through nymph stages
  - have roles
  - provide food

  - insects that spend most of their lives in water
  - modified in many ways for life in the water
  - noticeably absent from the undersides of all nest rocks
  - one of the trout's primary diets
  - the most important food of most stream fish
* begin as nymphs then turn into duns and finally die as spinners.
* can be useful indicators of environmental quality
  - breathe underwater
* consume air
  - the stored air while under water or use it to regulate buoyancy
* eat much of the debris from plants
* feed on benthic algae which is enhanced by nutrient additions.
* fly to find water to live in.
* go from being water breathing bottom crawlers to air breathing flies.
* have a short but critical adult stage, during which reproduction occurs
* live most of their lives underwater as nymphs or larva.
* make up the majority of a fish's diet.
* spend most of their life in water.
* transform to their adult forms.
* undergo simple metamorphosis or complete metamorphosis.

Assassin bug
* Most assassin bugs are generalist predators in gardens and fields.
* Some assassin bugs are excellent predators of the large bollworm larvae.
* is an insect

Backswimmer
* are other predators that can also inflict a strong bite.
* fly readily from pond to pond.
* have dark bellies
  - the ability to live on land or water
* swim upside-down on their backs just under the surface of the water.

Bed bug
* All bed bugs mate by traumatic insemination.
* Most bed bugs go through stages
  - have pads
* Most bed bugs live for months
  - several months
* Most bed bugs survive for few months
* Some bed bugs drink blood
  - feed at nights
  - survive years

* are active at night and generally hide during the day
  - mainly at night
  - only at night, usually just before dawn
  - also capable of feeding on animals, including dogs, cats, and other pets
  - attracted to the carbon dioxide emitted by their hosts

  - located in beds
  - nocturnal, that is, they feed at night, often biting people who are asleep

  - small, brownish, flattened insects that feed solely on the blood of animals
  - true bugs
  - very resilient and can easily survive for several months or more without a blood meal
  - wingless bloodsuckers of birds and mammals
* bite hosts.
* can live in almost any crevice or protected location
  - survive many months without a blood meal and they reproduce in an unusual fashion
* evolve in a process called simple metamorphosis.
* have ability
* hide in more than just mattresses.
* infest houses.
  - in folds of mattresses and bed covers
* mate in a bizarre process called traumatic insemination.
* occur throughout the world.
