Foraging behavior of insect pollinators in the presence of ambush predators

In this TIEE experiment, students investigate how ambush predators such as the common ambush bug (Phymata americana) or the common crab spider (Misumena vatia) influence the foraging behavior of insect pollinators on flowers. This project involves an experimental manipulation of predator presence and subsequent pollinator observation over the course of a single or several lab periods. Students read introductory articles and take a pre-project online quiz, collect data in the field, analyze the class data, interpret literature sources and write a major report.

Pedagogical Use Description This field activity could be used in two ways: (1) in upper-level (specialized) ecology courses (e.g. behavioral ecology or field ecology courses) for 12-20 undergraduate students using the instructions outlined in the present document, where students cooperatively collect their data, and (2) in upper-level, two-week summer field course settings as an individual student project. In the latter, the project approach should be more inquiry-based.
