Abstract

A snout weevil, Rhopalotria mollis Sharp, is found to complete the reproductive phases of its life cycle upon and within male cones of the cycad, Zamia furfuracea. Larvae of this insect feed upon tissues of the male cone, pupate, and emerge as pollen-coated adults after boring through microsporangia and microsporophylls. Mature weevils visit pollen-receptive female cones but are nondestructive to ovules and seeds. Exclusion experiments show that weevils are capable of effecting the pollination of ovules of Z. furfuracea in the absence of airborne pollen.
