- Results and Discussion
- Different cues are integrated to modulate head orientation
- Body orientation is mainly controlled by gravity and ground orientation

- Introduction
- Methods
- Results
- Black objects are approached independent of distance, but white objects are not attractive
- Camouflaged objects can be detected if they are away from the background
- Walking style does not change when confronted with different objects
- Discussion
- Blowflies employ motion cues to detect camouflaged objects
- Motion cues do not affect distance preferences of walking blowflies within short ranges
- Walking style of blowflies remains largely constant even when detecting camouflaged objects

- Attention is required to explain quick choices in free walking blowflies
- Introduction

- Animals and animal preparation
- Experimental setup
- Experimental procedure
- Modeling: Object Response Addition Model (ORAM)
- Modeling: Attention Model (AM)
- Results
- Object preferences depend on azimuth position.
- When approaching objects flies react quickly, regardless of object position
- Possible determinants of object choice
- Object response addition model (ORAM)
- Attention model
- The Attention Model reproduces the increasing predictive power of the most frontal object along the walk
- Discussion
- Decision time is minimally affected by object position or the possibility to choose between goals
- Attention is required to explain quick choices displayed by walking blowflies
