Figure 1.

Distribution of the pollinator Tegeticula elatella and the cheater T. intermedia in the United States. Pollinators are shown in grey circles and cheaters are shown in black. Site localities are solid circles, and open circles represent known localities that were not included in the present study. The numbers correspond to the site information presented in table 1. The fine dotted line represents a rough approximation of the cheater's host range (all host species combined), and the coarse dotted line is the host range for T. elatella (Y. elata). There are no known cheater populations or T. intermedia hosts in the area between sites 4 and 6.
