This fact was used in designing an apparatus to measure drink duration in flies (Dethier et al., 1956) and it is also the underlying principle of a now described apparatus to monitor feeding. One part of the circuit includes the animal's food and the other part includes the animal itself; thus, when the animal is eating the food the circuit is closed, and when it is not then the circuit is open. This apparatus was designed for use with the tobacco hornworm, but with slight modifications it could be used for many caterpillars and other types of insects. The apparatus (Fig. 1) consists of a round, 9-cmdiameter paraffin platform resting on a shelf(S 1) on a wooden base. Six pin plugs- simple electrical connectors with an insulated base and a single, pointed prong - are arranged at equal intervals around the periphery of the platform. The pins of the pin plugs project into the arena and the plastic insulated bases
