 Mole crickets are relatively common , but because they are nocturnal and spend nearly all their lives underground in extensive tunnel systems , they are rarely seen . They inhabit agricultural fields and grassy areas . They are present in every continent with the exception of Antarctica ; by 2014 , one hundred and seven species had been described and more species are likely to be discovered , especially in Asia . Neoscapteriscus didactylus is a widespread pest species , originating in South America it has spread to the West Indies and New South Wales in Australia . Gryllotalpa africana is a major pest in South Africa ; other Gryllotalpa species are widely distributed in Europe , Asia and Australia . They are native to Britain ( as to western Europe ) , but the former population of G. gryllotalpa may now be extinct in mainland Britain , surviving in the Channel Islands .
