Analysis of a contact zone in the Forficula auricularia L. (Dermaptera: Forficulidae) species complex in the Pyrenean Mountains

A Forficula auricularia L. (Dermaptera: Forficulidae), earwig insect, species-complex contact zone in the Pyrenees Mountains has been analyzed. Two sibling species differ in life history and have diverged at the molecular level. The PCR-RFLP method was used on two mitochondrial regions. Findings show coexistence of the sibling species at an intermediate altitude, but at lower and higher altitudes only one species was seen
