Figure 1

Sampling localities of the sympatric area.
Panel (A): geographic distribution of Aedes mariae (orange) and Ae. zammitii (light grey) along the coasts of the Italian Peninsula. The populations of Ae. mariae (Circeo and Scauri) used in the translocation experiment are also shown. Panels (B–F): sampling localities, years of collection and proportions of Ae. mariae (orange) and Ae. zammitii (light grey) in each locality. The number of Ae. mariae and Ae. zammitii individuals found are also shown (data from ref. 29). The sketch map was drawn using the software Canvas 15 (ACD systems http://www.acdsee.com/de/products/canvas-15) by tracing a map of the Gargano Promontory generated in QGIS 2.12 (http://www.qgis.org/it/site).
