Question

behavior. perhaps launching their frass is a way to avoid being found by predators.
to evaluate whether the smell of frass helps predators find and locate silver - spotted skippers, martha conducted an experiment with a wasp predator that eats these caterpillars. she allowed two silver - spotted skippers to build shelters on a leaf and then carefully removed the caterpillars. she then inserted 6 frass pellets into one of the shelters, and 6 beads designed to look like frass but with no smell (control treatment) into the other shelter. she placed the leaf with the two shelters in a cage containing an actively foraging wasp colony (n = 10 wasps). she recorded how many times the wasps visited each shelter (control beads or frass) and how much time the wasps spent exploring each shelter. she expected wasps would spend more time exploring the shelters with the frass than they would the control shelters.
scientific question: why do silver - spotted skippers launch their frass?
what is the hypothesis? find the hypothesis in the research back

Explanation:

A hypothesis is a proposed explanation for a phenomenon. In this experiment, Martha is testing whether the smell of frass helps predators find silver - spotted skippers. The expected outcome (wasps spending more time exploring frass - containing shelters) is based on the idea that the smell of frass aids predators. So, the hypothesis is that launching their frass is a way for silver - spotted skippers to avoid being found by predators (since if the frass smell attracts predators, launching it would remove that attractant).

Answer:

Perhaps launching their frass is a way to avoid being found by predators.
