Abstract
New records and a re-evaluation of published records of the flower preferences of P. vespoides show that the wasp restricts its flower visits almost exclusively to larger Penstemon species in Colorado. Pseudomasaris marginalis and P. zonalis are also relatively oligotropic species, confining their flower visits almost exclusively to Phacelia.This publication has 0 references indexed in Scilit:
