Description

Direct measurement of sugar-water consumption in butterflies by weighing individuals before and after feeding events using high-precision scales. Butterflies fed ad libitum on droplets of 1:3 sugar-water solution.

Typical Equipment

• high-precision 0.1 mg scale (Sartorius AG, Göttingen, Germany)
• forceps
• plastic plates

Output Measurements

• food intake
• sugar water consumption
