A Mean (± se) Melolontha hippocastani egg-cluster density and B mean (± se) egg density according to the presence-absence of a dense shrub layer. Estimates (± se) indicate coefficients and “P <”, P values from univariable generalized (negative binomial) linear models (egg-cluster and egg density ~ dense shrub presence). “n =” indicates the number of study plots in each category
