Engorgement in tick larvae and nymphs is primarily triggered by feeding on blood. During this feeding process, ticks attach themselves to a host and begin to ingest blood. As they consume blood, their bodies swell significantly, leading to engorgement. This process is essential for ticks' life cycle as it provides the necessary nutrients required for growth and development into their next life stage.

Other factors, such as movement, warmth, and environmental changes, do influence tick behavior or activity levels, but they do not directly cause engorgement. Movement can help ticks locate hosts, warmth can make a host more attractive, and environmental changes can affect tick habitats, but it is the actual feeding on blood that initiates the physiological process of engorgement.
