Question

Observation 2: Some caterpillar species are camouflaged in their appearance. They are generally very difficult to distinguish from their habitat. Additionally, these species are generally solitary. Based on this information, please answer the following questions 1. Generate a measurable hypothesis to explain these observations. 2. Based on your hypothesis generate a prediction about the behavior of insectivorous birds towards caterpillars. 3. Outline an investigation to test your hypothesis in the space below, identifying the dependent and independent variables. Additionally, make sure you address your controls and replicates!

Explanation / Answer

1. The inconspicuous caterpillars are difficult to locate due to their camouflage.

Hypothesis: The conspicuously colored caterpillars are unpalatable. The inconspicuous caterpillars are palatable. Their camouflage reduces their chance of being preyed upon by predators.
