Other claims from this paper (13)

Observation Hymenopterans predominated among major pollinators.
Observation Apis mellifera spent longer on A. syriaca than native hymenopterans and lepidopterans.
Observation Bumblebees visited more A. syriaca plants per bout.
Observation Carpenter bees visited more A. incarnata plants per bout.
Observation Wasps visited more A. verticillata plants per bout.
Observation Insect fidelity varied by season and plant species.
Observation Honeybees foraged with greater relative constancy on A. syriaca.
Observation Lepidopterans foraged with greater relative constancy on A. incarnata.
Observation Sphecid wasps foraged with greater relative constancy on A. verticillata.
Observation Bees and wasps carried more A. incarnata pollinaria than A. syriaca pollinaria.
Observation Bees and wasps carried more A. verticillata pollinaria than A. syriaca pollinaria.
Observation Most insects had higher inferred pollinium transfer rates on A. syriaca than its congeners, particularly sphecid wasps.
Association Indices from pre-contact foraging and pollinium loads were poorly congruent.

Other claims from this paper (4)

Observation Zenobia appears to be weakly self-compatible and partially self-pollinating.
Intervention effect Fruit set of Zenobia was reduced, but not eliminated, by excluding insect floral visitors.
