How do young bed bugs (nymphs) generally appear?

Young bed bugs, known as nymphs, typically appear translucent or whitish-yellow in color. This coloration is due to their immature state, which makes them less pigmented compared to adult bed bugs. Nymphs undergo several molts before reaching maturity, and during these stages, their body structure remains soft and pliable, contributing to their translucent appearance. As they feed on blood, they may also take on a reddish hue, but initially, they are more pale.

The other options describe features that do not accurately represent young bed bugs. Bright orange and winged does not correspond to nymphs, as these insects are wingless and not brightly colored at that stage. Opaque black might describe some other insects in their adult forms, but it does not match the young bed bugs, which have a more translucent quality. Lastly, the description of being large and brown with a hard exterior better fits the adult bed bug, which is significantly different from the appearance of nymphs.
