De veenmol Gryllotalpa gryllotalpa al ruim 100 jaar op texel aanwezig (Orthoptera)

The presence of the mole cricket Gryllotalpa gryllotalpa on the Dutch wadden island Texel (Orthoptera) This note addresses the distribution of the mole cricket (Gryllotalpa gryllotalpa (Linnaeus, 1758)) on the Dutch wadden island Texel. In 1998 and 1999, records of this species were published in a local newspaper. Later, more records got known. Until then, there were no known records of this species of Texel nor from the adjacent mainland. It became known that in the year 1900 large numbers of nests of mole crickets were found in a tree nursery on the island and that a population had been living in the surrounding area all through the 20th century. The large numbers in the nursery may suggest a non-native origin, however, no significant numbers of young trees nor tree lumps are believed to have been imported into Texel. Therefore, it is concluded that the species is most likely native on the island, although a non-native origin on the island can not be ruled out entirely.
