Do different tree species host different types of insects? Flowering trees tend to attract more insects than evergreens. This project compares what lives on three different kinds of trees. You spread a white sheet under a branch and tap it with a stick. Insects fall onto the sheet. You collect up to five from each branch in small vials. After sampling three branches per tree, you chill the insects in a refrigerator to slow them down. Then you examine each one under a magnifying lens and use a dichotomous key (a step-by-step identification chart) to find its order. Compare which trees host the most insects and whether the same orders appear on all three.
