What are newly hatched scale insects referred to as?

Newly hatched scale insects are referred to as "crawlers." This term is used specifically for the first instar nymph stage of scale insects, which emerges from the eggs after hatching. These crawlers are mobile, unlike the adult scale insects and subsequent life stages that are typically sessile and immobile as they attach themselves to plant surfaces.

The term captures their nature of being in a phase where they actively move to find suitable places on plants to settle down and feed. Understanding the terminology related to different life stages of pests like scale insects is crucial for effective pest management and control strategies, especially when applying pesticides or biological controls.
