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.

Life Table and Reproductive Traits of Eumerus obliquus (Diptera: Syrphidae) Reared in Captivity

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Age‐stage specific survival rate (above) and daily averages of oviposition and hatching (below) of Eumerus obliquus under captive conditions. The curve illustrates the probability that a newly laid egg will survive to a specific age and stage. The results revealed a positive population growth trend, the larval stage being the most critical phase in the
