| Eoferreola rhombica, a pompilid new to the Dutch fauna, and its remarkable host, Eresus sandaliatus (Hymenoptera: Pompilidae; Araneae: Eresidae) In 1998 a female specimen of Eoferreola rhombica (Christ, 1791) was collected in a road-verge on the Veluwe. The nearest populations of this species are found in northern France and eastern Germany. It is possible that this insect was transported by traffic from one of these populations. However at the collection site a large population of the rare host spider Eresus sandaliatus (Martini & Goeze, 1778) is known to be present for many years. Therefore the presence of a population of E. rhombica cannot be excluded. Future observations have to reveal the status of this spider wasp in the Netherlands. |
