"Aphaniptera includes the fleas, which, despite their minuteness, have made themselves a name in the world. The arterial covering is a horny compound of very distinct segmentsl the wings are four, but nearly rudimentary; the suctional organs consist of a pair of fine, serrated, sword-shaped mandibles, provided with a sharp, needle-like spear for penetrating the skin of the victim." &mdash; Goodrich, 1859

An illustration of a common flea. Once the flea reaches adulthood its primary goal is to find blood - adult fleas must feed on blood in order to reproduce. Adult fleas only have around a week to find food once they emerge, though they can survive two months to a year between meals. A flea population is unevenly distributed, with 50 percent eggs, 35 percent larvae, 10 percent pupae and 5 percent adults. Their total life cycle can take as little as two weeks, but may be lengthened to many months if conditions are unfavorable. Female fleas can lay 500 or more eggs over their life, allowing for phenomenal growth rates.

An illustration of the larva of a common flea. Flea larvae emerge from the eggs to feed on any available organic material such as dead insects, feces and vegetable matter. They are blind and avoid sunlight, keeping to dark places like sand, cracks and crevices, and bedding. Given an adequate supply of food, larvae should pupate within 1-2 weeks. After going through three larval stages they spin a silken cocoon.

An illustration of the pupa of a common flea. After going through three larval stages they spin a silken cocoon. After another week or two the adult flea is fully developed and ready to emerge from the cocoon. They may however remain resting during this period until they receive a signal that a host is near - vibrations (including sound), heat and carbon dioxide are all stimuli indicating the probable presence of a host. Fleas are known to overwinter in the larval or pupal stages.

The chigoe flea (Tunga penetrans) is a parasitic arthropod found in tropical climates, especially South America and the West Indies. At 1 mm long, the chigoe flea is the smallest known flea. Breeding female chigoes burrow into exposed skin and lay eggs, causing intense irritation. After this point, the skin lesion looks like a 5 to 10 mm white spot with a central black dot, which are the flea's exposed hind legs, respiratory spiracles and reproductive organs.

Cheese flies are members of the family Piophilidae of flies (Diptera), including the members of two now-obsolete families, Neottiophilidae and Thyreophoridae. Most are scavengers in animal products and fungi. The best-known member of the family is Piophila casei. It is a small fly, about four mm (1/6 inch) long, found worldwide. The fly's larva infests cured meats, smoked fish, cheeses, and decaying animals. The larva is about 8 mm (1/3 inch) long and is sometimes called the cheese skipper for its leaping ability - when disturbed, this tiny maggot can hop up to 15 cm (6 inches) into the air. Adults are also known as "bacon flies" and their larvae as "bacon skippers", "ham skippers", "cheese maggots", and "cheese hoppers". In Sardinia, Italy the larvae are intentionally introduced into pecorino cheese to produce casu marzu.
