What can cause these very tiny dark red (almost black) insects that bite, jump fast, itch and leave red swellings?

Not sure - A chigger: Is only about 1/60 inch. Sometimes you can see a cluster of small red chiggers together. Chigger's bites often have a small red in the center of a welt & occur in areas where skin is tender like the crotch, armpits, beltline, backs of knees, ankles. They are extremely itchy.
