Plant–animal interactions

Cover Page

On the cover A cocoo wasp Hedychrum gerstaeckeri (Hymenoptera, Chrysididae), feeding on pollen of a daisy fleabane (Erigeron annuus) – an example of complexity of plant–animal interactions. Hedychrum gerstaeckeri is a kleptoparasite laying eggs in the nests of Crabronidae wasps (e.g., Cerceris rybyensis, Philantus triangulum), and exploiting the eggs, larvae and food deposits of the host. The Crabronidae wasps in turn provide their larvae with hunted honey bees (Apis mellifera). All these adult hymenopterans feed on pollen and nectar.
