| A new record of Microdon devius in the central part of the province of Limburg (Diptera: Syrphidae) In 1997 a male of the hoverfly Microdon devius (Linnaeus, 1761) was collected near Weert, in the central part of the province of Limburg in the Netherlands. The only other record from the same area was from the Meynweg in 1990. The nearest population in the Netherlands of this rare species is found in the southernmost part of Limburg. The heath vegetation at the site near Weert harbours a relatively large population of the ant Lasius flavus, the possible host of the larvae of M. devius. |

| On the occurrence of Otiorhynchus dieckmanni in the Netherlands (Coleoptera: Curculionidae) In 1994 Otiorhynchus dieckmanni was collected for the first time in the Netherlands in a garden in Helvoirt (Noord-Brabant). Since then the species was recorded from several other localities far apart from each other, in the provinces of Noord-Brabant, Limburg, Flevoland and Noord-Holland. On one locality at Weert (Limburg), the species was collected in two consecutive years; on another locality, Heemstede (Noord-Holland), one teneral specimen was found. These data strongly suggest that O. dieckmanni is now well established in the Netherlands. |
