Relationship of Lebia grandis mass (newly-emerged carabid adult) versus host mass (Leptinotarsa prepupa). Slope of regression line is significantly different from zero only for Leptinotarsa decemlineata (solid yellow line: y = 6.51 + 0.172X (n = 13, p= 0.008, R2adj = 0.44)); however, slopes for the three hosts do not differ; the significant effect of host is attributable to a reduced mean Lebia mass for those parasitizing Leptinotarsa haldemani, compared to the other two species. Means and standard errors are shown for each host.
