Top to bottom: human flea (Pulex), eyelash mite (Demodex) and a louse (Pediculus)
Here is a great medical entomology website. An ectoparasite is a parasite that lives on or in the skin rather than inside the body. Humans can become infested with many different ectoparasites. Some are pretty much harmless (head lice) and others can transmit disease (ticks, fleas, mites). Some ectoparasites live in the skin. For instance the scabies mite.
Learn more about scabies (mites) here, it's something you could possibly see. You can visit these websites to learn about head lice, ticks that spread Lyme Disease, body lice, and dust mites (not an ectoparasite but a cause of allergy). Here is a paper that discusses eyelash mites (demodex) and rosacea.
Some diseases spread by ectoparasites include: Babesiosis (ticks), Plague (fleas) and scrub typhus (mites).
