Determining Predator Identity From Attack Marks Left In Model Caterpillars


“The use of model caterpillars to assess relative rates of predation has risen in popularity in recent years. Among the various benefits of the technique is its capacity to provide information on the identity of attackers through the impressions left in the modeling clay from which the model prey is constructed. However, there currently exists no detailed information on how to assign attack marks to particular predators. We…address this gap by collating a comprehensive reference collection of the types of marks made by different predators. This serves as a guide for researchers wanting to identify the predators responsible for attacks.”

NOTE: This data is from Australia, and may not be directly applied to North America. However, it details a great approach to be used.
