List of Tiny Insects

By Calia Roberts

Insects are one of the most diverse groups of animals in the world. They live in almost any environment, either alone or in a colony-like setting. Tiny insects live all around us, which are just visible or possibly not visible at all to the naked eye. Some tiny insects such as fleas bite and sting, some are allergy irritants such as dust mites and some are simply an annoyance such as flies.

Biting Midge

A biting midge, the smallest blood-sucking insect known to man, will grow to approximately 1 mm in length. These insects are so tiny they are often are referred to as "no-see-ums" as they are difficult to see with the naked eye. Biting midges are winged insects similar to mosquitoes. They live around lakes and rivers, and the female midges will attack exposed skin, leaving behind an itchy and uncomfortable bite.

Fairy Flies

Fairy flies are one of the smallest insects in the world, measuring less than 3 mm in length. These insects are not truly flies, but actually tiny parasites called Mymaridae wasps, which lay their eggs in the inside of other insect's eggs and are born adults. The main characteristic of this insect is its vein-less paddle-shaped wings, which are edged with long fringe like hairs, much like fairy wings.

Angel Insect

Angel insects, or Zorapterans, are small and delicate, measuring no more than 3 mm in length when fully grown. These tiny insects are much like termites. They live in rotting bark, wood, leaf litter and trees. Angel insects are also fungal spore scavengers and will occasionally eat small mites. Two adult types of Angel insects exist: a pale, wingless, blind adult and a dark, large-winged adult with compound eyes. The winged adult is able to shed its wings when needed. Both adult types have biting mouths and triangular heads.

Pharaoh Ant

The pharaoh ant is one of the smallest of the ant species, measuring approximately 1 1/16 inches in length when fully grown. These ants will nest anywhere, especially in buildings with artificial heat or in dark, undisturbed places. Pharaoh ant infestations are difficult to control as the colony, which is home to several queens, will be moved at the first sign of disturbance. When the colony is disturbed, a queen along with several workers and pre-adults will simply create a new colony at a different location. Professional help is generally necessary when dealing with a pharaoh ant infestation.
