This is a photomicrograph of a female ham mite, a species of the suborder Sarcoptiformes. This is a tick of the genus Ixodes in the nymphal stage of its life cycle. This is a male Ixodes ricinus tick (smaller) shown copulating with a female tick (larger). This is a Sarcoptes scabiei var. hominis or “itch mite”, often associated with the transmission of human scabies. This is a female “Lone star tick”, Amblyomma americanum, and is found in the southeastern and midatlantic United States.

This photograph of 2 ticks was taken during a 1972 study of disease carriers and pests found in and around migrant labor camps. This illustration shows the growth stages of the “American dog tick”, Dermacentor variabilis, from eggs to adult insects. This illustration reveals the morphologic characteristics on the ventral surface of the male mite Laelaps nuttalli. This drawing reveals the morphologic features on the ventral surface of the protonymph staged mite, Laelaps nuttalli. This illustration reveals the morphologic characteristics on the dorsal surface of the female mite Dermanyssus gallinae.
