Tachinidae (Diptera) as Floral Visitors and Pollinators in Natural and Managed Systems

open access: yesEntomologia 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.

Is urbanisation a barrier to genetic diversity in the solitary specialist bee, Melissodes druriellus?

open access: yesInsect Conservation and Diversity, EarlyView.
Bees are integral pollinators commonly found in and supported by urban green spaces; however, their eco‐evolutionary response to urbanisation varies interspecifically. While several studies have explored the population and landscape genetics of bees in response to urbanisation, few have examined solitary or specialist species which may be more ...
