Fifty leafhoppers new to Belgium (Hemiptera: Cicadellidae).
Leafhoppers or Cicadellidae are the largest family of the Auchenorrhyncha in Belgium, however, this family did not yet receive a lot of attention. In a short time-span, 50 species were found that were not previously reported for the Belgian fauna. Three of these are alien species from outside Europe that recently colonised Belgium and another six live on introduced plants and could therefore also be considered as alien species. Several southern species recently colonised Belgium, possibly due to climate changes. For two of these, the present records are even the northernmost so far. However, most species were just overlooked in the past due to the limited attention for leafhoppers in Belgium.
