Pea aphids, Acyrthosiphon pisum, are small, wingless, sap-sucking insects that live on plants. They evade predators (such as ladybugs) by dropping off of the plants. A study examined the mechanism of aphid drops. Researchers placed aphids on a leaf positioned at four different heights (in centimeters, cm) above a surface covered with petroleum jelly. When a ladybug was introduced, the aphids dropped, and the petroleum jelly helped capture their landing posture (upright or not). Each aphid performed this experiment only once. The finds are presented in the table.
