Purple corn borer ( Pyrausta purpuralis )

The Crambidae, called by some authors Rüsselzünsler, are a family of butterflies. Of them, about 11,700 species are known worldwide until now. Most species have their distribution in tropical regions, while in central Europe, only about 230 species are endemic.


The animals are characterized by a special form of Tympanalorgans and the veins in the fore wings, and thereby of the Zünslern ( Pyralidae ) distinguished. The trunk is often atrophied or absent. Caterpillars are slightly hairy, doll in the cocoon. Most forms are also slightly smaller than the representative of the corn borer.

Way of life

Within the family, a great diversity of life is observed as well in the other family of Pyraloidea, the Zünslern. These include not only the usual storage pests and leaves eaters also groups whose caterpillars have an aquatic lifestyle. They live in the stems of aquatic plants. Also can be found at the Crambidae many caterpillars that feed on roots. Most species feed as leaf miners.


Currently, the family is divided into 17 subfamilies, 12 of which have representatives in Central Europe.
