What is a common characteristic of bed bug nymphs?

Bed bug nymphs share many characteristics with adult bed bugs, but they differ significantly in size and developmental stage. Nymphs are immature forms of bed bugs and resemble adults in body shape and features, such as the flattened, oval-shaped body, but they are smaller and not yet fully developed. This resemblance helps them integrate visually into environments that adults inhabit, making them less likely to be detected.

The other options are not accurate reflections of the characteristics of nymphs. For instance, nymphs do not have the ability to fly, as bed bugs are wingless throughout their life stages. Additionally, since nymphs are not fully grown, they cannot be classified as such. Lastly, all stages of bed bugs, including nymphs, possess distinct body segments, so nymphs do not lack body segments. The defining feature of nymphs being smaller, undeveloped versions of adults is key to understanding their role in bed bug life cycles and control methods.
