Applied behavior analysis. Applied behavior analysis (ABA) is a scientific discipline concerned with analyzing the principles of learning and behavioral control, developing usable methods from these principles, and systematically applying these methods to change behavior of social significance.
A botfly, also written bot fly, bott fly or bot-fly in various combinations, is any fly in the family Oestridae. Their lifecycles vary greatly according to species, but the larvae of all species are internal parasites of mammals.
Outside of North America there are a few other bugs that can live under our skin. The only one that I have ever seen in a patient is the human botfly. These flies live in Central and South America. The adult lays eggs in our skin that hatch into larvae that are about 1/2 inch long.
