Food plants and foraging distances for the native bee Lasioglossum sordidum in Christchurch Botanic Gardens

With concerns about declines in pollinating bee species worldwide, there is renewed interest in solitary native bee species and their role in pollination services. We studied the foraging preferences and foraging distances of Lasioglossum sordidum (Halictidae), New Zealand’s smallest solitary bee, in urban Christchurch. Lasioglossum sordidum were abundant within the Christchurch Botanic Gardens. Pollen samples taken from 40 bees at each of two nest sites were identified using a pollen reference collection from the sites.
