What Is The Correct Anatomical Location On A Queen Bee For Applying A Marking Dot? A Guide To Safe Queen Marking

The correct anatomical location for marking a queen bee is the dorsal side of the thorax. Specifically, you must aim for the small, bald area situated directly behind her head and centered between her wings.

Precision is critical when marking a queen to ensure her safety and mobility. Apply the mark exclusively to the thorax—the rigid center section of her body—to provide a stable anchor for the ink without interfering with her vital functions.

Identifying the Exact Target Zone

The Thorax

The queen's body is divided into three sections: the head, the thorax (middle), and the abdomen (rear).

You must focus entirely on the thorax. This is the section where the legs and wings attach.

The Bald Patch

On the top of the thorax, there is a distinct, small area that is relatively hairless.

This spot is located behind the head and strictly between the wings. This is the only safe canvas for your marker or sticker.

Why This Location is Critical

Structural Stability

The thorax provides a hard, rigid surface that does not change shape.

Unlike the abdomen, which expands and contracts for egg production and breathing, the thorax remains static. This ensures the mark does not crack or flake off due to body movement.

Non-Interference with Function

Marking this specific spot ensures the queen retains full physical capability.

As noted in the primary reference, a mark placed here does not interfere with the queen's ability to lay eggs or move throughout the hive. It keeps foreign substances away from her sensory organs and propulsion mechanisms.

Critical Mistakes to Avoid

Avoiding the Wings

You must be extremely careful not to get ink or glue on the wings.

If the wings are glued together or to the body, the queen cannot fly or maintain proper balance. This often leads to the colony rejecting or killing her (supersedure).

Avoiding the Abdomen

Never place a mark on the long, tapered abdomen section.

The abdomen contains spiracles (breathing pores) and needs to stretch significantly. Paint here can block respiration or cause irritation that prompts worker bees to groom the mark—and the queen—too aggressively.

Ensuring a Successful Application

To apply the mark effectively without harming the queen, consider your specific goal:

If your primary focus is safety: Ensure the queen is fully immobilized in a marking cage or plunger so that only the thorax is exposed through the mesh.
If your primary focus is durability: Target the specific bald patch on the thorax, as ink adheres much better to the exoskeleton than to the distinct hairs surrounding it.

Mastering this simple anatomical distinction is the first step toward effective colony management.

Summary Table:

Anatomical Section	Marking Safety	Reason for Success/Risk
Thorax (Center)	Safe & Recommended	Rigid surface; doesn't interfere with breathing or egg-laying.
Bald Patch	Optimal Target	Provides the best adhesion for ink and stickers away from hairs.
Abdomen (Rear)	Dangerous	Contains breathing spiracles and must expand for egg production.
Wings	Dangerous	Glue or ink on wings prevents flight and leads to queen rejection.
Head	Dangerous	Risk of blocking sensory organs and vision.
