Use Of The Mouth Parts Of Orthoptera During Feeding (1960)

You asked for it! The film explores the feeding mechanics of grasshoppers, specifically the species Aria sufuria and Romalia microptera. It details the process known as margin feeding, where grasshoppers cut and chew leaves using their specialized mouth parts: the labrum, mandibles, maxillae, and labium. The mandibles are asymmetrical, allowing for effective cutting and grinding of food. The sequence of feeding involves incision followed by mastication, with the maxillae assisting in food alignment. The film highlights the intricate functions of each mouth part and how they work together during the feeding process.
