Abstract

Initial orientation and homing time were recorded in Argogorytes carbonarius after displacement in “open” and “closed” containers during two periods: “first” release dates and “later” release dates. At the later releases “closed” wasps homed much better than at first releases and better than “open” wasps. At the first releases, on the other hand, the “open” wasps homed (slightly) better than the “closed” wasps. An interpretation relates the better homing of “closed” wasps at the later trials to route learning at the first trials and discusses the differences and peculiarities of homing from familiar terrain and of home orientation by path integration.
