Colombia is the second-most species-rich country in flower fly diversity in the Neotropics after Brazil, and has one of the highest numbers of species per unit area (2.49 per 10,000 km 2), based on a review of literature and national collections. Including new data presented here, a total of 47 genera and 300 species are recorded in Colombia. The genera Scaeva Fabricius and Lycastrirhyncha Bigot, as well as 101 species are recorded here for the first time. The altitudinal range and the distribution of the flower fly genera in Colombia are presented. A preliminary comparison of the fauna of Colombia with that of other Neotropical countries is given. A historical perspective is also provided in order to illustrate how Colombian Syrphidae knowledge has progressed over the last 168 years. Information presented here will be useful for ongoing and future biodiversity research as well as conservation projects on Syrphidae in the Neotropical region.

The immature stages of P. chalconota were compared with the third-stage larva and puparium of the best-studied species in the genus Platycheirus scutatus (Meigen, 1822); as well as with the only known Carposcalis immature stages description available for the Neotropical region namely Platycheirus stegnus (Say, 1829). New data on trophic interactions and larval habitats are given: P. chalconota larvae were found feeding on the aphid's species Uroleucon sonchi (Linnaeus, 1767) (large sow thistle aphid) and Hyperomyzus lactucae (Linnaeus, 1758) (blackcurrant-sow thistle aphid) in low vegetation as Sonchus oleraceus (common sow thistle); the species was also found feeding on Myzus persicae (Sulzer, 1776) (green ...

(Diptera: Syrphidae) is described based on a single male collected in pristine rainforest in the Amazonian region of Colombia (type-locality: Florencia, Caquetá) and two females from a conserved forest in Suriname (Para and Brokopondo). Copestylum enriquei sp. nov. belongs to the C. vagum species group and is similar in appearance to Copestylum vagum (Wiedemann), C. musicanum (Curran), C. tenorium Ricarte & Rotheray, and C. chapadensis (Curran) from which it differs by the gena and face separated by a very broad brown vitta; scutum orange except for the wide medial vitta, which is dark and metallic, ending before the prescutellar region, with the apical margin M-shaped; tibiae dark-brown, except yellow on basal 1/4. The male genitalia of C. enriquei sp. nov. are unique and striking among the C. vagum species group, characterized by the epandrium and cercus black, contrasting with the colour of hypandrium and s...

The medical, ecological and sanitary importance of these flies resides in their feeding and development habits, which occur in excrement, garbage, decomposing organic matter and animal carcasses. In addition, they are mechanical vectors of pathogens and causal agents of myiasis. The objective of this study was to determine the synanthropic index (SI) of adult Calliphoridae in La Pintada-Antioquia, Colombia, through simultaneous monthly samplings in three environments (urban, rural, and forest) using van Someren Rydon traps baited with human excrement, decomposing chicken viscera, fish and onion. Four traps (one for each bait) were placed in each environment for 48 hours each month, making collections every 12 hours. A total of 2406 individuals was captured belonging to 10 species. Chysomya megacephala (SI = + 96.47) showed the strongest preference for dense...
