Preening and immune defense each lowered mean puparium mass significantly (see text for statistics). Asterisks indicate significant differences between bars with Pā<ā0.05. The top bar represents a significant effect of immune priming on puparia mass, comparing puparia produced by flies on birds that have been immunologically primed to those that have not been primed. The lower bar represents a significant effect of preening within the immune primed group.
