Conservation Biology, EarlyView.Abstract Bees play a pivotal role in terrestrial environments. Urbanization can affect these organisms and the ecosystem services they provide. However, knowledge of the global diversity of urban bees is limited. Thus, we summarized data on urban bee species identities and occurrences; compared distributions of all bees with those found in urban ...

Tachinidae (Diptera) as Floral Visitors and Pollinators in Natural and Managed Systems
Entomologia Experimentalis et Applicata, EarlyView.We review the roles of bristle flies (Tachinidae) as pollinators in natural and managed systems. We find that most tachinid genera visit flowers and that floral‐adapted mouthparts have evolved repeatedly many times in the family. We review patterns of floral specificity and assess the efficacy of tachinids as pollinators with case studies.

Entomologia Experimentalis et Applicata, EarlyView.Spanolepis selloanae (Diptera, Cecidomyiidae) infests Cortaderia selloana (pampas grass). It lays eggs in the spikelets, where larvae feed on female parts. The high prevalence of the midge and its combined impact in seed production, condition and viability strongly reduces the reproductive output of C. selloana.
