flyPAD vs FLIC: Comparing Automated Feeding Detection Systems
Both systems automate Drosophila feeding measurement. Here's how they differ in practice.
The flyPAD and FLIC (Fly Liquid-food Interaction Counter) are both automated systems designed to detect and quantify feeding behavior in Drosophila without manual observation. While they share the goal of removing observer bias and providing temporal resolution, their underlying technology, resolution, and extensibility differ in practice.
This comparison helps you determine which platform better fits your experimental needs, budget, and long-term research direction.
Side-by-Side Comparison
| Criterion | flyPAD | FLIC |
|---|---|---|
| Detection method | Capacitance-based sensing | Electrical contact signal |
| Data output rate | 100 Hz (10 ms) | 5 Hz (200 ms) |
| Food types | Solid + liquid | Liquid only |
| Optogenetics | optoPAD — closed-loop (feeding-triggered) | OptoLid — programmable LEDs |
| Software | Bonsai (open-source) | Proprietary |
| Multi-species validated | Mosquito, ant, bee, Drosophila | Drosophila only |
| Publication | Nature Communications, 2014 | PLoS ONE, 2014 |
Automation
You put in flies and food — the system does the rest: publication-grade figures and more than 20 quantitative metrics of feeding behavior, complete with statistical analysis.

Food Flexibility
flyPAD's capacitance detection works with both solid and liquid food, while FLIC requires liquid food. This makes flyPAD more versatile for diet manipulation studies.
Optogenetics Integration
Both platforms support optogenetics. flyPAD's optoPAD runs in closed loop — stimulation is triggered in real time by the fly's own detected feeding, letting you build "virtual taste realities." FLIC's OptoLid delivers programmable LED stimulation on a preset schedule.
Species Versatility
flyPAD has been validated in published research for mosquitoes, ants, and bees in addition to Drosophila. FLIC has been primarily validated for Drosophila use.
