Phorid Flies (Insecta: Diptera: Phoridae) of the Nectandra Cloud Forest Reserve in Mid-Elevation Costa Rica Open
The Costa Rican mid-elevation forests have been found to include some of the richest sites in the world for biodiversity per unit area. We used DNA barcodes to study 28,773 phorid fly specimens that were Malaise-trapped in the Nectandra Cl…

Review of wing morphology in fossil and modern species of humpbacked flies (Diptera: Phoridae) Open
Background The wing veins of known fossil and living phorids are reduced, making them difficult to homologise. Consequently, different interpretations have led to much confusion over the years. However, veins are crucial for phylogenetic a…

The stridulatory organ in Opetiidae and Phoridae (Diptera) and phylogenetic implications for the evolution of higher flies Open
Stridulatory sound-making organs evolved in a group of flies—the family Phoridae—by modifications of the microstructure of foreleg segments present in the shared ancestor of the clade (Phoridae + Opetiidae). The opetiids are the only group…

Global invasion risk of Apocephalus borealis, a honey bee parasitoid Open
Apocephalus borealis is a parasitoid of hymenopterans native to North America that also attacks introduced honey bees ( Apis mellifera ). Parasitism by this species has been associated with infested bees absconding the hive and dying outsi…

Announcing Big-Bee: An initiative to promote understanding of bees through image and trait digitization Open
While bees are critical to sustaining a large proportion of global food production, as well as pollinating both wild and cultivated plants, they are decreasing in both numbers and diversity. Our understanding of the factors driving these d…

Response to Zamani et al. (2020): The omission of critical data in the pursuit of “revolutionary” methods to accelerate the description of species Open
Here we respond to the criticisms leveled against a proposal that suggested an efficient solution to the taxonomic impediment. We clarify some of our objectives and demonstrate that many of the criticisms apply more to traditional approach…
