The Ant Double Y-Maze is a specialized behavioral testing apparatus designed for investigating decision-making and lateralized behaviors in ants. This miniaturized maze features a unique double Y-shaped configuration with four goal arms, providing researchers with a sophisticated tool for studying ant cognition and behavioral preferences. The maze structure consists of a single longitudinal entrance channel that branches into two symmetrical Y-shaped arms arranged perpendicular to each other.
Adapted from standard Y-maze protocols used in rodent studies, this apparatus enables researchers to examine how sensory asymmetries and nervous system lateralization influence ant behavior. The compact dimensions (10mm arm length, 2mm arm width) are specifically optimized for ant species, while the integrated petri dish design facilitates observation and data collection. This tool is particularly valuable for investigations into spatial memory, choice behavior, and neurobiological mechanisms underlying decision-making in social insects.
How It Works
The Ant Double Y-Maze operates on the principle of forced choice behavioral testing, where individual ants must make sequential decisions between available pathways. The maze design presents subjects with an initial choice point at the entrance, followed by secondary choice points in each arm, creating a hierarchical decision-making scenario. This configuration allows researchers to assess both initial preferences and subsequent behavioral adaptations.
The apparatus exploits ants' natural exploratory behavior and spatial navigation abilities. As subjects traverse the maze, researchers can record arm entries, time spent in each section, and turning preferences to quantify behavioral patterns. The double Y-configuration provides four distinct goal areas, enabling analysis of choice consistency, preference strength, and potential lateralization effects in ant behavior.
Data collection typically involves tracking individual ant movements through video recording or direct observation, with measurements including latency to first choice, total exploration time, and frequency of visits to each arm. The maze's compact scale and transparent construction facilitate accurate behavioral scoring while maintaining naturalistic movement patterns for the test subjects.

Practical Tips
Test ants during their natural active periods (typically early morning or evening) for optimal behavioral responses.
Why: Circadian activity patterns significantly influence exploration and decision-making behaviors in ants.
Inspect maze junctions regularly for debris or damage that could impede ant movement between arms.
Why: Even small obstructions can alter movement patterns and introduce unwanted behavioral variables.
Record ambient temperature and humidity for each testing session to identify environmental influences on behavior.
Why: Ant activity levels and movement speeds are temperature-dependent, affecting choice latencies and exploration patterns.
Use known ant species with documented behavioral preferences to validate maze function before experimental trials.
Why: Establishes baseline performance and confirms the apparatus is producing expected behavioral responses.
If ants show reluctance to enter arms, verify that cleaning agents have completely evaporated and check for static electricity buildup.
Why: Residual chemicals or electrostatic forces can create invisible barriers that deter natural exploratory behavior.
Mark individual ants with non-toxic paint dots for repeated testing while avoiding interference with sensory organs.
Why: Individual identification enables within-subject analysis and tracking of learning or habituation effects across trials.
Handle ants with soft brushes or gentle aspiration to prevent injury and stress responses that could affect behavior.
Why: Physical stress from rough handling can alter normal behavioral patterns and compromise experimental validity.

Protocol and background
Introduction
The Ant Double Y-maze is used to study decision-making and lateralized behaviors of ants. It consists of a Y-shaped cavity that branches into two additional Y-shaped cavities. The Ant Double Y-maze is a modification of the standard Y-maze that is used in rodents and utilizes the same decision-making protocol.
Sensory organs of animals help them gather information about their surroundings. Since sensory organs are part of the nervous system, further examinations reveal how the left and right asymmetries in the nervous system affect the behaviors of animals (Frasnelli, Vallortigara, & Rogers, 2014). The Ant Double Y-maze can be used to observe how ants make a biased choice towards the left or right maze arm. These choices can be used to evaluate behaviors associated with their lateralized nervous system. Essentially, the maze can be applied to observe decision-making behaviors in ants for mating, foraging, and finding shelter under different experimental protocols. Further, the effects of diseases and disorders of the nervous system, brain lesions, pharmacological manipulations on learning, foraging, and mating behaviors can also be evaluated.
Other apparatuses used in the evaluation of ant behaviors include the Ant Binary Tree Maze, the Ant T-Maze, the Ant Double Bifurcation T-Maze, and the Ant Colony Maze.
Apparatus and Equipment
The Ant Double Y-maze is placed in the center of a 50 mm x 75 mm x 1.8 mm. The maze has one longitudinal entrance channel and two symmetrical branching cavities that are perpendicular to each other. Each branch is equipped with a Y-Maze giving a total of 4 goal arms. All the arms of the maze measure 10 mm in length and 2 mm in width. The apparatus also comes with large Petri dishes (230 x 230 x 19 mm) to hold stimuli at the end of the four branches.
Training protocol
Wash the perimeter with water after every trial. Appropriately light the maze. A tracking and recording system such as the Noldus Ethovision XT can be used to assist with observations.
Ant Double Y-maze task
Connect the colony to the Double Y-maze’s entry arm and allow the subjects to enter the maze. Allow the subjects to explore the maze, make their choices and consume the reward (if any) at the ends of the goal arms. Remove the subject from the apparatus once the choice is made and mark the subjects if required. Conduct trials until 7 ants are picked from each branching direction.
The protocol may vary depending on investigatory requirements.
Evaluation of behavioral lateralization in ants
Hunt et al. (2018) studied behavioral lateralization in Temnothorax albipennis on an Ant Double Y-maze. Four ant colonies were assessed for their spatial resolution in connection with their behavioral roles within the colony. Additionally, the possible link between externally observable asymmetries in compound eyes and lateralization was also investigated. When colonies were destroyed and connected to the maze entrance, scouting ants looked for a replacement nest site. After they entered the branching cavity, 7 ants that chose each secondary branch (left and right) were selected. After trials ended, 56 worker ants, 18 queens (10 were from different colonies not used in the experiment), and 4 males were sampled, euthanized, and their heads were sectioned for observation of their ommatidia under a microscope. For the 56 worker ants that were examined 45% had more ommatidia in the right eye, 36% had more ommatidia in the left eye, and 20% had an equal number. It was observed that the ants that turned left had more ommatidia on their right eyes and those that turned right had more ommatidia on their left eyes which showed a significant connection between their asymmetry and turning direction. Furthermore, the males had more ommatidia compared to the worker ants and the queens.
Data Analysis
The following parameters can be observed on an Ant Double Y-maze:
- Number of entries into the left branching cavity
- Number of entries into the right branching cavity
- Number of entries into the right goal arm (via left branching cavity)
- Number of entries into the left goal arm (via left branching cavity)
- Number of entries into the right goal arm (via right branching cavity)
- Number of entries into the left goal arm (via right branching cavity)
Strengths and Limitations
Strengths
The Ant Double Y-maze can be used to study different behavioral assays in ants such as decision-making behaviors for mating, foraging, and finding shelter. It can also be used to study diseases and disorders of the nervous system in ants. It is easy to operate and allows easy acquisition of data. Training of subjects is not required using the Ant Double Y-maze which saves time.
Limitations
Olfactory cues present from previous subjects may affect task performance. Proper cleaning of the apparatus is highly important. Mishandling of the subjects may induce stress or anxiety causing significant disturbance to the subject’s behavior. Task performance may be influenced by age, gender, and strain of the subjects.
