During a 2-month field study of sympatric Peromyscus maniculatus (Deer Mouse) and Peromyscus truei (pinyon mouse), 12/152 (7.9 percent) P. maniculatus and 1/45 (2.2 percent) P. truei were parasitized by Cuterebra larvae. Both parasitized P. maniculatus and P. truei and nonparasitized P. maniculatus selected different habitats in the community. Differential parasitism of P. maniculatus and P. truei was possibly caused by host specificity of Cuterebra, whereas differential parasitism of P. maniculatus may have been due to habitat selection.
