Topographic-climatic map of Israel showing the distribution of morphologically identified <i>Culicoides schultzei</i> complex (<i>n</i> = 217) sampled at 15 collection sites.

<p>Pie diagrams represent proportion of <i>C. oxystoma</i> (white) and <i>C. schultzei</i> gp. (dark gray) that were distinguished based on their ITS-1 sequence size. Arrow - collection site (Yotvata) where <i>C. schultzei</i> complex midges were absent. Numbers represent trap location sites (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0033610#pone-0033610-t001" target="_blank">table 1</a>).
