Margined Vine Chafer Anomala dubia
The Margined Vine Chafer is a very variable species. Usually it looks like the Bracken Chafer: brown shields. But it always shines metallically even through the brown shields: usually green, but sometimes blue or scarlet. And the shields are not always brown! In grass lands the rookworms are extremely devastating. Adult chafers are mainly seen in June and July. The rookworm lives about the same way as the Garden Chafer's. When conditions are good, the development from egg to chafer takes just one year. When conditions are less good the development takes two years. The Margined Vine Chafer is found on sandy soils only. It is very common in our dunes.
