Host plant richness and abundance drive populations of a super‐generalist xylem‐feeding insect

open access: yesEcological Entomology, EarlyView.
Philaenus spumarius abundance was assessed across 93 sites and four habitat types (olive groves, vineyards, meadows, and field margins) within eight heterogeneous agricultural landscapes over the year. In spring, nymph abundance was positively associated with herbaceous plant species richness and vegetation cover, highlighting that even super ...
