Title

Specificity in Pollen Consumption of Oligolectic Solitary Bees in Öland, Sweden

Presenter

Jessie Austin

Abstract

Adult solitary bees consume pollen and nectar for their sustenance and females also collect both to feed their young. Oligolectic solitary bees are specialists in terms of what flowers they visit to collect pollen; however, their degree of specialization in the pollen they consume has not been clearly documented. My goal was to determine the species composition of pollen in the digestive tract of four oligolectic bee species in Öland, Sweden. Bees were dissected to obtain a sample of pollen from their gut, and the pollen was identified under the microscope. Dissection of over 20 bees for each species revealed that the composition of gut pollen was over 97% from the bee’s host plants. These findings indicate that the bees display uniform specificity towards pollen (consumption, collection) and that the term “oligolecty” should be expanded to include not only pollen collection for nest provisioning but also pollen consumption by adults.
